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.

* ramips: set WAN address in DTS for ASUS RT-AC51U/RT-AC54UAdrian Schmutzler2020-05-183-4/+5
| | | | | | | | | | | | | The location 0x28 in factory partition is the common one used for ethernet address on this architecture. Despite, it contains the label MAC address for the devices at hand. Consequently, this patch moves 0x28 to the &ethernet node in DTS files (setting the WAN MAC address there) and sets up the lan_mac from 0x22 in 02_network. As a benefit, this allows to use label-mac-device in DTS instead of ucidef_set_label_macaddr. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

* mt7621: Make ER-X-SFP factory image compatible with EP-R6Fabian Bläse2020-05-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The version inside the compat file determines, if a firmware supports a specific device. I have not yet fully understood, how this is checked, but it only seems to indicate which devices are supported by a specific version of the combined vendor firmware. Devices assume that subsequent versions, starting with the version that initially added support for a specific device, are always compatible. The first compat version that added support for the EP-R6 was '21001:7', but OpenWrt did use '21001:6' before. This is why the factory image could not be flashed using the vendor software, but only using TFTP. The compat version has been bumped by the vendor a few times, but more devices have been added since (e.g. ER-10X). Because OpenWrt currently only supports the ER-X, ER-X-SFP and EP-R6, the compat version is incremented to the version that first supported the EP-R6, which is '21001:7'. This allows the factory image to be flashed on EP-R6 without TFTP. Signed-off-by: Fabian Bläse <fabian@blaese.de>

They are similar to the TP9343-based TL-WR940N v3/v4 and TL-WR941ND v6. Specifications: SoC: TP9343 Flash/RAM: 4/32 MiB CPU: 750 MHz WiFi: 2.4 GHz b/g/n Ethernet: 1 port (100M) Flashing instructions: Upload the factory image via the vendor firmware upgrade option. Flash instruction (TFTP): 1. Set PC to fixed ip address 192.168.0.66 2. Download *-factory.bin image and rename it to * (see below) 3. Start a tftp server with the image file in its root directory 4. Turn off the router 5. Press and hold Reset button 6. Turn on router with the reset button pressed and wait ~15 seconds 7. Release the reset button and after a short time the firmware should be transferred from the tftp server 8. Wait ~30 second to complete recovery. * The image name for TFTP recovery is wa901ndv4_tp_recovery.bin for both variants. In ar71xx, a MAC address with offset 1 was used for ethernet port. That's probably wrong, but this commit sticks to it until we know the correct value. Like in ar71xx, this builds the default factory.bin with EU country code.

* ramips: add support for Linksys EA7500 v2Davide Fioravanti2020-05-177-0/+259

Hardware -------- SoC: Mediatek MT7621AT (880 MHz, 2 cores 4 threads) RAM: 256M (Nanya NT5CC128M16IP-DI) FLASH: 128MB NAND (Macronix MX30LF1G18AC-TI) ETH: 5x 10/100/1000 Mbps Ethernet (MT7530) WIFI: - 2.4GHz: 1x MT7615N (4x4:4) - 5GHz: 1x MT7615N (4x4:4) - 4 antennas: 3 external detachable antennas and 1 internal USB: - 1x USB 3.0 - 1x USB 2.0 BTN: - 1x Reset button - 1x WPS button LEDS: - 1x White led (Power) - 6x Green leds (link lan1-lan4, link wan, wps) - 5x Orange leds (act lan1-lan4, act wan) (working but unmodifiable) Everything works correctly. Installation ------------ The “factory” openwrt image can be flashed directly from OEM stock firmware. After the flash the router will reboot automatically. However, due to the dual boot system, the first installation could fail (if you want to know why, read the footnotes). If the flash succeed and you can reach OpenWrt through the web interface or ssh, you are done. Otherwise the router will try to boot 3 times and then will automatically boot the OEM firmware (don’t turn off the router. Simply wait and try to reach the router through the web interface every now and then, it will take few minutes). After this, you should be back in the OEM firmware. Now you have to flash the OEM Firmware over itself using the OEM web interface (I tested it using the FW_EA7500v2_2.0.8.194281_prod.img downloaded from the Linksys website). When the router reboots flash the “factory” OpenWrt image and this time it should work. After the OpenWrt installation you have to use the sysupgrade image for future updates. Restore OEM Firmware -------------------- After the OpenWrt flash, the OEM firmware is still stored in the second partition thanks to the dual boot system. You can switch from OpenWrt to OEM firmware and vice-versa failing the boot 3 times in a row: 1) power on the router 2) wait 15 seconds 3) power off the router 4) repeat steps 1-2-3 twice more. 5) power on the router and you should be in the “other” firmware If you want to completely remove OpenWrt from your router, switch to the OEM firmware and then flash OEM firmware from the web interface as a normal update. This procedure will overwrite the OpenWrt partition. Footnotes --------- The Linksys EA7500-v2 has a dual boot system to avoid bricks. This system works using 2 pair of partitions: 1) "kernel" and "rootfs" 2) "alt_kernel" and "alt_rootfs". After 3 failed boot attempts, the bootloader tries to boot the other pair of partitions and so on. This system is managed by the bootloader, which writes a bootcount in the s_env partition, and if successfully booted, the system add a "zero-bootcount" after the previous value. A system update performed from OEM firmware, writes the firmware on the other pair of partitions and sets the bootloader to boot the new pair of partitions editing the “boot_part” variable in the bootloader vars. Effectively it's a quick and safe system to switch the selected boot partition. Another way to switch the boot partition is: 1) power on the router 2) wait 15 seconds 3) power off the router 4) repeat steps 1-2-3 twice more. 5) power on the router and you should be in the “other” firmware In this OpenWrt port, this dual boot system is partially working because the bootloader sets the right rootfs partition in the cmdline but unfortunately OpenWrt for ramips platform overwrites the cmdline so is not possible to detect the right rootfs partition. Because all of this, I preferred to simply use the first pair of partitions and set read-only the other pair. However this solution is not optimal because is not possible to know without opening the case which is the current booted partition. Let’s take for example a router booting the OEM firmware from the first pair of partitions. If we flash the OpenWrt image, it will be written on the second pair. In this situation the router will bootloop 3 times and then will automatically come back to the first pair of partitions containg the OEM firmware. In this situation, to flash OpenWrt correctly is necessary to switch the booting partition, flashing again the OEM firmware over itself. At this point the OEM firmware is on both pair of partitions but the current booted pair is the second one. Now, flashing the OpenWrt factory image will write the firmware on the first pair and then will boot correctly. If this limitation in the ramips platform about the cmdline will be fixed, the dual boot system can also be implemented in OpenWrt with almost no effort.
