This is to make life easier for users with customized build of
dnsmasq-full variant. Currently dnsmasq config generated by current
service script will be rejected by dnsmasq build lacking DHCP feature
- Options like --dhcp-leasefile have default values. Deleting them
from uci config or setting them to empty value will make them take on
default value in the end
- Options like --dhcp-broadcast are output unconditionally
Tackle this by
- Check availablility of features from output of "dnsmasq --version"
- Make a list of options guarded by HAVE_xx macros in src/options.c of
dnsmasq source code
- Ignore these options in xappend()
Two things to note in this implementation
- The option list is not exhaustive. Supposedly only those options that
may cause dnsmasq to reject with "unsupported option (check that
dnsmasq was compiled with DHCP/TFTP/DNSSEC/DBus support)" are taken
into account here
- This provides a way out but users' cooperation is still needed. E.g.
option dnssec needs to be turned off, otherwise the service script
will try to add --conf-file pointing to dnssec specific anchor file
which dnsmasq lacking dnssec support will reject

There was an issue with the backport compat layer in yesterday's snapshot,
causing issues on certain (mostly Atom) Intel chips on kernels older than
4.2, due to the use of xgetbv without checking cpu flags for xsave support.
This manifested itself simply at module load time. Indeed it's somewhat tricky
to support 33 different kernel versions (3.10+), plus weird distro
frankenkernels.
If OpenWRT doesn't support < 4.2, you probably don't need to apply this.
But it also can't hurt, and probably best to stay updated.

* tools: add wincompat layer to wg(8)
Consistent with a lot of the Windows work we've been doing this last cycle,
wg(8) now supports the WireGuard for Windows app by talking through a named
pipe. You can compile this as `PLATFORM=windows make -C src/tools` with mingw.
Because programming things for Windows is pretty ugly, we've done this via a
separate standalone wincompat layer, so that we don't pollute our pretty *nix
utility.
* compat: udp_tunnel: force cast sk_data_ready
This is a hack to work around broken Android kernel wrapper scripts.
* wg-quick: freebsd: workaround SIOCGIFSTATUS race in FreeBSD kernel
FreeBSD had a number of kernel race conditions, some of which we can vaguely
work around. These are in the process of being fixed upstream, but probably
people won't update for a while.
* wg-quick: make darwin and freebsd path search strict like linux
Correctness.
* socket: set ignore_df=1 on xmit
This was intended from early on but didn't work on IPv6 without the ignore_df
flag. It allows sending fragments over IPv6.
* qemu: use newer iproute2 and kernel
* qemu: build iproute2 with libmnl support
* qemu: do not check for alignment with ubsan
The QEMU build system has been improved to compile newer versions. Linking
against libmnl gives us better error messages. As well, enabling the alignment
check on x86 UBSAN isn't realistic.
* wg-quick: look up existing routes properly
* wg-quick: specify protocol to ip(8), because of inconsistencies
The route inclusion check was wrong prior, and Linux 5.1 made it break
entirely. This makes a better invocation of `ip route show match`.
* netlink: use new strict length types in policy for 5.2
* kbuild: account for recent upstream changes
* zinc: arm64: use cpu_get_elf_hwcap accessor for 5.2
The usual churn of changes required for the upcoming 5.2.
* timers: add jitter on ack failure reinitiation
Correctness tweak in the timer system.
* blake2s,chacha: latency tweak
* blake2s: shorten ssse3 loop
In every odd-numbered round, instead of operating over the state
x00 x01 x02 x03
x05 x06 x07 x04
x10 x11 x08 x09
x15 x12 x13 x14
we operate over the rotated state
x03 x00 x01 x02
x04 x05 x06 x07
x09 x10 x11 x08
x14 x15 x12 x13
The advantage here is that this requires no changes to the 'x04 x05 x06 x07'
row, which is in the critical path. This results in a noticeable latency
improvement of roughly R cycles, for R diagonal rounds in the primitive. As
well, the blake2s AVX implementation is now SSSE3 and considerably shorter.
* tools: allow setting WG_ENDPOINT_RESOLUTION_RETRIES
System integrators can now specify things like
WG_ENDPOINT_RESOLUTION_RETRIES=infinity when building wg(8)-based init

EAP-pwd missing commit validation
Published: April 10, 2019
Identifiers:
- CVE-2019-9497 (EAP-pwd server not checking for reflection attack)
- CVE-2019-9498 (EAP-pwd server missing commit validation for
scalar/element)
- CVE-2019-9499 (EAP-pwd peer missing commit validation for
scalar/element)
Latest version available from: https://w1.fi/security/2019-4/
Vulnerability
EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP
peer) was discovered not to validate the received scalar and element
values in EAP-pwd-Commit messages properly. This could result in attacks
that would be able to complete EAP-pwd authentication exchange without
the attacker having to know the used password.
A reflection attack is possible against the EAP-pwd server since the
hostapd EAP server did not verify that the EAP-pwd-Commit contains
scalar/element values that differ from the ones the server sent out
itself. This allows the attacker to complete EAP-pwd authentication
without knowing the password, but this does not result in the attacker
being able to derive the session key (MSK), i.e., the attacker would not
be able to complete the following key exchange (e.g., 4-way handshake in
RSN/WPA).
An attack using invalid scalar/element values is possible against both
the EAP-pwd server and peer since hostapd and wpa_supplicant did not
validate these values in the received EAP-pwd-Commit messages. If the
used crypto library does not implement additional checks for the element
(EC point), this could result in attacks where the attacker could use a
specially crafted commit message values to manipulate the exchange to
result in deriving a session key value from a very small set of possible
values. This could further be used to attack the EAP-pwd server in a
practical manner. An attack against the EAP-pwd peer is slightly more
complex, but still consider practical. These invalid scalar/element
attacks could result in the attacker being able to complete
authentication and learn the session key and MSK to allow the key
exchange to be completed as well, i.e., the attacker gaining access to
the network in case of the attack against the EAP server or the attacker
being able to operate a rogue AP in case of the attack against the EAP
peer.
While similar attacks might be applicable against SAE, it should be
noted that the SAE implementation in hostapd and wpa_supplicant does
have the validation steps that were missing from the EAP-pwd
implementation and as such, these attacks do not apply to the current
SAE implementation. Old versions of wpa_supplicant/hostapd did not
include the reflection attack check in the SAE implementation, though,
since that was added in June 2015 for v2.5 (commit 6a58444d27fd 'SAE:
Verify that own/peer commit-scalar and COMMIT-ELEMENT are different').
Vulnerable versions/configurations
All hostapd versions with EAP-pwd support (CONFIG_EAP_PWD=y in the build
configuration and EAP-pwd being enabled in the runtime configuration)
are vulnerable against the reflection attack.
All wpa_supplicant and hostapd versions with EAP-pwd support

hostapd: fix SAE confirm missing state validation
Published: April 10, 2019
Identifiers:
- CVE-2019-9496 (SAE confirm missing state validation in hostapd/AP)
Latest version available from: https://w1.fi/security/2019-3/
Vulnerability
When hostapd is used to operate an access point with SAE (Simultaneous
Authentication of Equals; also known as WPA3-Personal), an invalid
authentication sequence could result in the hostapd process terminating
due to a NULL pointer dereference when processing SAE confirm
message. This was caused by missing state validation steps when
processing the SAE confirm message in hostapd/AP mode.
Similar cases against the wpa_supplicant SAE station implementation had
already been tested by the hwsim test cases, but those sequences did not
trigger this specific code path in AP mode which is why the issue was
not discovered earlier.
An attacker in radio range of an access point using hostapd in SAE
configuration could use this issue to perform a denial of service attack
by forcing the hostapd process to terminate.
Vulnerable versions/configurations

configuration and SAE being enabled in the runtime configuration).

EAP-pwd side-channel attack
Published: April 10, 2019
Identifiers:
- CVE-2019-9495 (cache attack against EAP-pwd)
Latest version available from: https://w1.fi/security/2019-2/
Vulnerability
Number of potential side channel attacks were recently discovered in the
SAE implementations used by both hostapd and wpa_supplicant (see
security advisory 2019-1 and VU#871675). EAP-pwd uses a similar design
for deriving PWE from the password and while a specific attack against
EAP-pwd is not yet known to be tested, there is no reason to believe
that the EAP-pwd implementation would be immune against the type of
cache attack that was identified for the SAE implementation. Since the
EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP
peer) does not support MODP groups, the timing attack described against
SAE is not applicable for the EAP-pwd implementation.
A novel cache-based attack against SAE handshake would likely be
applicable against the EAP-pwd implementation. Even though the
wpa_supplicant/hostapd PWE derivation iteration for EAP-pwd has
protections against timing attacks, this new cache-based attack might
enable an attacker to determine which code branch is taken in the
iteration if the attacker is able to run unprivileged code on the victim
machine (e.g., an app installed on a smart phone or potentially a
JavaScript code on a web site loaded by a web browser). This depends on
the used CPU not providing sufficient protection to prevent unprivileged
applications from observing memory access patterns through the shared
cache (which is the most likely case with today's designs).
The attacker could use information about the selected branch to learn
information about the password and combine this information from number
of handshake instances with an offline dictionary attack. With
sufficient number of handshakes and sufficiently weak password, this
might result in full recovery of the used password if that password is
not strong enough to protect against dictionary attacks.
This attack requires the attacker to be able to run a program on the
target device. This is not commonly the case on an authentication server
(EAP server), so the most likely target for this would be a client
device using EAP-pwd.
The commits listed in the end of this advisory change the EAP-pwd
implementation shared by hostapd and wpa_supplicant to perform the PWE
derivation loop using operations that use constant time and memory
access pattern to minimize the externally observable differences from
operations that depend on the password even for the case where the
attacker might be able to run unprivileged code on the same device.
Vulnerable versions/configurations
All wpa_supplicant and hostapd versions with EAP-pwd support
(CONFIG_EAP_PWD=y in the build configuration and EAP-pwd being enabled
in the runtime configuration).
It should also be noted that older versions of wpa_supplicant/hostapd
prior to v2.7 did not include additional protection against certain
timing differences. The definition of the EAP-pwd (RFC 5931) does not
describe such protection, but the same issue that was addressed in SAE
earlier can be applicable against EAP-pwd as well and as such, that
implementation specific extra protection (commit 22ac3dfebf7b, "EAP-pwd:
Mask timing of PWE derivation") is needed to avoid showing externally
visible timing differences that could leak information about the
password. Any uses of older wpa_supplicant/hostapd versions with EAP-pwd
are recommended to update to v2.7 or newer in addition to the mitigation
steps listed below for the more recently discovered issue.
Possible mitigation steps
- Merge the following commits to wpa_supplicant/hostapd and rebuild:
OpenSSL: Use constant time operations for private bignums
Add helper functions for constant time operations
OpenSSL: Use constant time selection for crypto_bignum_legendre()

SAE side-channel attacks
Published: April 10, 2019
Identifiers:
- VU#871675
- CVE-2019-9494 (cache attack against SAE)
Latest version available from: https://w1.fi/security/2019-1/
Vulnerability
Number of potential side channel attacks were discovered in the SAE
implementations used by both hostapd (AP) and wpa_supplicant
(infrastructure BSS station/mesh station). SAE (Simultaneous
Authentication of Equals) is also known as WPA3-Personal. The discovered
side channel attacks may be able to leak information about the used
password based on observable timing differences and cache access
patterns. This might result in full password recovery when combined with
an offline dictionary attack and if the password is not strong enough to
protect against dictionary attacks.
Cache attack
A novel cache-based attack against SAE handshake was discovered. This
attack targets SAE with ECC groups. ECC group 19 being the mandatory
group to support and the most likely used group for SAE today, so this
attack applies to the most common SAE use case. Even though the PWE
derivation iteration in SAE has protections against timing attacks, this
new cache-based attack enables an attacker to determine which code
branch is taken in the iteration if the attacker is able to run
unprivileged code on the victim machine (e.g., an app installed on a
smart phone or potentially a JavaScript code on a web site loaded by a
web browser). This depends on the used CPU not providing sufficient
protection to prevent unprivileged applications from observing memory
access patterns through the shared cache (which is the most likely case
with today's designs).
The attacker can use information about the selected branch to learn
information about the password and combine this information from number
of handshake instances with an offline dictionary attack. With
sufficient number of handshakes and sufficiently weak password, this
might result in full discovery of the used password.
This attack requires the attacker to be able to run a program on the
target device. This is not commonly the case on access points, so the
most likely target for this would be a client device using SAE in an
infrastructure BSS or mesh BSS.
The commits listed in the end of this advisory change the SAE
implementation shared by hostapd and wpa_supplicant to perform the PWE
derivation loop using operations that use constant time and memory
access pattern to minimize the externally observable differences from
operations that depend on the password even for the case where the
attacker might be able to run unprivileged code on the same device.
Timing attack
The timing attack applies to the MODP groups 22, 23, and 24 where the
PWE generation algorithm defined for SAE can have sufficient timing
differences for an attacker to be able to determine how many rounds were
needed to find the PWE based on the used password and MAC
addresses. When the attack is repeated with multiple times, the attacker
may be able to gather enough information about the password to be able
to recover it fully using an offline dictionary attack if the password
is not strong enough to protect against dictionary attacks. This attack
could be performed by an attacker in radio range of an access point or a
station enabling the specific MODP groups.
This timing attack requires the applicable MODP groups to be enabled
explicitly in hostapd/wpa_supplicant configuration (sae_groups
parameter). All versions of hostapd/wpa_supplicant have disabled these
groups by default.
While this security advisory lists couple of commits introducing
additional protection for MODP groups in SAE, it should be noted that
the groups 22, 23, and 24 are not considered strong enough to meet the
current expectation for a secure system. As such, their use is
discouraged even if the additional protection mechanisms in the
implementation are included.

current security expectations. The groups 22, 23, and 24 are related
to the discovered side channel (timing) attack. The other groups in
the list are consider too weak to provide sufficient security. Note
that all these groups have been disabled by default in all

have to. Before we tried to cheat by giving our own address as the
destination, but this had the unfortunate effect of preventing
loopback from working on our local ip address. We work around this with
yet another kludge: we set the destination address to 127.0.0.1. Since
127.0.0.1 is already assigned to an interface, this has the same effect
of not specifying a destination address, and therefore we accomplish the
intended behavior. Note that the bad behavior is still present in Darwin,
where such workaround does not exist.
* tools: remove unused check phony declaration
* highlighter: when subtracting char, cast to unsigned
* chacha20: name enums
* tools: fight compiler slightly harder
* tools: c_acc doesn't need to be initialized
* queueing: more reasonable allocator function convention
Usual nits.
* systemd: wg-quick should depend on nss-lookup.target
Since wg-quick(8) calls wg(8) which does hostname lookups, we should
probably only run this after we're allowed to look up hostnames.
* compat: backport ALIGN_DOWN
* noise: whiten the nanoseconds portion of the timestamp
This mitigates unrelated sidechannel attacks that think they can turn
WireGuard into a useful time oracle.
* hashtables: decouple hashtable allocations from the main device allocation
The hashtable allocations are quite large, and cause the device allocation in
the net framework to stall sometimes while it tries to find a contiguous
region that can fit the device struct. To fix the allocation stalls, decouple
the hashtable allocations from the device allocation and allocate the
hashtables with kvmalloc's implicit __GFP_NORETRY so that the allocations fall
back to vmalloc with little resistance.
* chacha20poly1305: permit unaligned strides on certain platforms
The map allocations required to fix this are mostly slower than unaligned
paths.
* noise: store clamped key instead of raw key
This causes `wg show` to now show the right thing. Useful for doing
comparisons.
* compat: ipv6_stub is sometimes null
On ancient kernels, ipv6_stub is sometimes null in cases where IPv6 has
been disabled with a command line flag or other failures.
* Makefile: don't duplicate code in install and modules-install
* Makefile: make the depmod path configurable
* queueing: net-next has changed signature of skb_probe_transport_header
A 5.1 change. This could change again, but for now it allows us to keep this
snapshot aligned with our upstream submissions.
* netlink: don't remove allowed ips for new peers
* peer: only synchronize_rcu_bh and traverse trie once when removing all peers
* allowedips: maintain per-peer list of allowedips
This is a rather big and important change that makes it much much faster to do
operations involving thousands of peers. Batch peer/allowedip addition and
clearing is several orders of magnitude faster now.

Currently it seems impossible to configure /etc/config/dhcp to achieve
the following use case
- run dnsmasq with no-resolv
- re-generate /etc/resolv.conf with "nameserver 127.0.0.1"
Before this change, we have to set resolvfile to /tmp/resolv.conf.auto
to achive the 2nd effect above, but setting resolvfile requires noresolv
being false.
A new boolean option "localuse" is added to indicate that we intend to
use dnsmasq as the local dns resolver. It's false by default and to
align with old behaviour it will be true automatically if resolvfile is
set to /tmp/resolv.conf.auto

Opkg treats text after a version number as higher than without:
~# opkg compare-versions "2.80rc1" "<<" "2.80"; echo $?
1
~# opkg compare-versions "2.80rc1" ">>" "2.80"; echo $?
0
This causes opkg not offering final release as upgradable version, and
even refusing to update, since it thinks the installed version is
higher.
This can be mitigated by adding ~ between the version and the text, as ~
will order as less than everything except itself. Since 'r' < 't', to
make sure that test will be treated as lower than rc we add a second ~
before the test tag. That way, the ordering becomes
2.80~~test < 2.80~rc < 2.80
which then makes opkg properly treat prerelease versions as lower.

* tools: curve25519: handle unaligned loads/stores safely
This should fix sporadic crashes with `wg pubkey` on certain architectures.
* netlink: auth socket changes against namespace of socket
In WireGuard, the underlying UDP socket lives in the namespace where the
interface was created and doesn't move if the interface is moved. This
allows one to create the interface in some privileged place that has
Internet access, and then move it into a container namespace that only
has the WireGuard interface for egress. Consider the following
situation:
1. Interface created in namespace A. Socket therefore lives in namespace A.
2. Interface moved to namespace B. Socket remains in namespace A.
3. Namespace B now has access to the interface and changes the listen
port and/or fwmark of socket. Change is reflected in namespace A.
This behavior is arguably _fine_ and perhaps even expected or
acceptable. But there's also an argument to be made that B should have
A's cred to do so. So, this patch adds a simple ns_capable check.

This adds a wrapper (uci_load_validate) for uci_validate_section() that
allows callers (through a callback function) to access the values set by
uci_validate_section(), without having to manually declare a
(potentially long) list of local variables.
The callback function receives two arguments when called, the config
section name and the return value of uci_validate_section().
If no callback function is given, then the wrapper exits with the value
returned by uci_validate_section().
This also updates several init scripts to use the new wrapper function.

The most relevant fix for openwrt is 18eac67 (& my own local f52bb5b
which fixes a missing bracket silly) To quote the patch:
It is possible for a config entry to have one address family specified by a
dhcp-host directive and the other added from /etc/hosts. This is especially
common on OpenWrt because it uses odhcpd for DHCPv6 and IPv6 leases are
imported into dnsmasq via a hosts file.
To handle this case there need to be separate *_HOSTS flags for IPv4 and IPv6.
Otherwise when the hosts file is reloaded it will clear the CONFIG_ADDR(6) flag
which was set by the dhcp-host directive.

The new samba36-hotplug package provides a hotplug.d script for the
"mount" subsystem. It automatically shares every mounted block device.
It works by updating /var/run/config/samba file which:
1) Is read by procd init script
2) Gets wiped on reboot providing a consistent state
3) Can be safely updated without flash wearing or conflicting with user
changes being made in /etc/config/samba

This will allow automation/hotplug.d scripts to store runtime shares in
the /var/run/config/samba. It's useful e.g. for USB drives that user
wants to be automatically shared.
Using /var/run/config/ provides:
1) Automated cleaning on reboots
It's important for consistency (to avoid sharing non-existing drives)
2) Safety for user non-commited changes
Automated scripts should never call "uci [foo] commit" as that could
flush incomplete config.
Another minor gain is avoiding flash wearing for runtime setup.

Interface triggers are installed by the dropbear init script in case an
interface is configured for a given dropbear uci section.
As dropbear is started after network the interface trigger event can be
missed during a small window; this is especially the case if lan is

Fix this by starting dropbear before network so no interface trigger
is missed. As dropbear is started earlier than netifd add a boot function
to avoid the usage of network.sh functions as call to such functions will

This is based on the requirements in the Wifi alliance document
Opportunistic_Wireless_Encryption_Specification_v1.0_0.pdf
The wifi alliance requires ieee80211w for the OWE mode.
This also makes it possible to configure the OWE transission mode which
allows it operate an open and an OWE BSSID in parallel and the client
should only show one network.
This increases the ipkg size by 5.800 Bytes.

This build the full openssl and wolfssl versions with SAE support which
is the main part of WPA3 PSK.
This needs elliptic curve cryptography which is only provided by these
two external cryptographic libraries and not by the internal
implementation.
The WPA3_Specification_v1.0.pdf file says that in SAE only mode
Protected Management Frames (PMF) is required, in mixed mode with
WPA2-PSK PMF should be required for clients using SAE, and optional for
clients using WPA2-PSK. The defaults are set now accordingly.
This increases the ipkg size by 8.515 Bytes.

dnsmasq v2.80test8 adds the ability to ignore dhcp client's requests for
specific hostnames. Clients claiming certain hostnames and thus
claiming DNS namespace represent a potential security risk. e.g. a
malicious host could claim 'wpad' for itself and redirect other web
client requests to it for nefarious purpose. See CERT VU#598349 for more
details.
Some Samsung TVs are claiming the hostname 'localhost', it is believed
not (yet) for nefarious purposes.
/usr/share/dnsmasq/dhcpbogushostname.conf contains a list of hostnames
in correct syntax to be excluded. e.g.
dhcp-name-match=set:dhcp_bogus_hostname,localhost
Inclusion of this file is controlled by uci option dhcpbogushostname
which is enabled by default.
To be absolutely clear, DHCP leases to these requesting hosts are still
permitted, but they do NOT get to claim ownership of the hostname
itself and hence put into DNS for other hosts to be confused/manipulate by.

* Try all combinations of different implementations in selftests, so that

* Self tests and SIMD glue code work with #include, which lets the compiler
optimize these. Previously these files were .h, because they were included,
but a simple grep of the kernel tree shows 259 other files that carry out
this same pattern. Only they prefer to instead name the files with a .c
instead of a .h, so we now follow the convention.
* Support many more platforms in QEMU, especially big endian ones.

OpenWrt used to ship hardcoded defaults for lcp-echo-failure and
lcp-echo-interval in the non-uci /etc/ppp/options file.
These values break uci support for *disabling* LCP echos through
the use of "option keepalive 0" as either omitting the keepalive
option or setting it to 0 will result in no lcp-echo-* flags
getting passed to the pppd cmdline, causing the pppd process to
revert to the defaults in /etc/ppp/options.
Address this issue by letting the uci "keepalive" option default
to the former hardcoded values "5, 1" and by removing the fixed
lcp-echo-failure and lcp-echo-interval settings from the
/etc/ppp/options files.

Update to latest git HEAD in order to support configuring multiple
concurrent Lua prefixes in a single uhttpd instance:
b741dec lua: support multiple Lua prefixes
Additionally rework the init script and update the default configuration
example to treat the lua_prefix option as key=value uci list, similar to
the interpreter extension mapping. Support for the old "option lua_prefix"
plus "option lua_handler" notation is still present.
Finally drop the sed postinstall hack in uhttpd-mod-lua to avoid mangling
files belonging to other packages. Since Lua prefixes have precedence
over CGI prefixes, simply register `/cgi-bin/luci` as Lua handler which
will only become active if both luci-base and uhttpd-mod-lua is installed.

Unauthenticated EAPOL-Key decryption in wpa_supplicant
Published: August 8, 2018
Identifiers:
- CVE-2018-14526
Latest version available from: https://w1.fi/security/2018-1/
Vulnerability
A vulnerability was found in how wpa_supplicant processes EAPOL-Key
frames. It is possible for an attacker to modify the frame in a way that
makes wpa_supplicant decrypt the Key Data field without requiring a
valid MIC value in the frame, i.e., without the frame being
authenticated. This has a potential issue in the case where WPA2/RSN
style of EAPOL-Key construction is used with TKIP negotiated as the
pairwise cipher. It should be noted that WPA2 is not supposed to be used
with TKIP as the pairwise cipher. Instead, CCMP is expected to be used
and with that pairwise cipher, this vulnerability is not applicable in
practice.
When TKIP is negotiated as the pairwise cipher, the EAPOL-Key Key Data
field is encrypted using RC4. This vulnerability allows unauthenticated
EAPOL-Key frames to be processed and due to the RC4 design, this makes
it possible for an attacker to modify the plaintext version of the Key
Data field with bitwise XOR operations without knowing the contents.
This can be used to cause a denial of service attack by modifying
GTK/IGTK on the station (without the attacker learning any of the keys)
which would prevent the station from accepting received group-addressed
frames. Furthermore, this might be abused by making wpa_supplicant act
as a decryption oracle to try to recover some of the Key Data payload
(GTK/IGTK) to get knowledge of the group encryption keys.
Full recovery of the group encryption keys requires multiple attempts
(128 connection attempts per octet) and each attempt results in
disconnection due to a failure to complete the 4-way handshake. These
failures can result in the AP/network getting disabled temporarily or
even permanently (requiring user action to re-enable) which may make it
impractical to perform the attack to recover the keys before the AP has
already changes the group keys. By default, wpa_supplicant is enforcing
at minimum a ten second wait time between each failed connection
attempt, i.e., over 20 minutes waiting to recover each octet while
hostapd AP implementation uses 10 minute default for GTK rekeying when
using TKIP. With such timing behavior, practical attack would need large
number of impacted stations to be trying to connect to the same AP to be
able to recover sufficient information from the GTK to be able to
determine the key before it gets changed.
Vulnerable versions/configurations
All wpa_supplicant versions.
Acknowledgments
Thanks to Mathy Vanhoef of the imec-DistriNet research group of KU
Leuven for discovering and reporting this issue.
Possible mitigation steps
- Remove TKIP as an allowed pairwise cipher in RSN/WPA2 networks. This
can be done also on the AP side.
- Merge the following commits to wpa_supplicant and rebuild:
WPA: Ignore unauthenticated encrypted EAPOL-Key data
This patch is available from https://w1.fi/security/2018-1/
- Update to wpa_supplicant v2.7 or newer, once available
