![]() ![]() The firmware images are both signed and encrypted with PGP, the signing key is also different from the encryption key. Please make a pull request with the dump if you do! I also found a few hidden firmware rollback and update links assuming that the router is using the 192.168.1.1 IP: & Firmware images/dumpsĬurrently nobody has a NAND dump of the older firmware that could hold the decryption/encryption keys/methods. The 4 CPU UART ports are ZigBee Rolling back your firmware ( creds) There are apparently multiple serial ports named UART0, UART1, UART2, and UART3 In the uBoot logs, the router seems to be opening a rw console on UART0. The debug console is disabled for the UART pins on the router board. ![]() Note that disconnecting the ssh session will require you to repeat the process. The router's ssh server should listen on the wan side port 22222. InternetGatewayDevice.X_D4A928_SSH_Session_Password It will then generate a temporary root ssh password available by querying getParameterValues for To enable the tr-069 backdoor, you need to send this setParameterValues request using the acs server These are the config file encryption/decryption scripts I'm using: You can however change the config file to disable ssl and point it at your own acs server, the config file is aes encrypted but I have some python scripts that can decrypt and re-encrypt the config file so that it can be edited(I had to get some help with reversing the encryption scheme from the assembly for that). Redirecting the router to a local acs server is a bit tricky though, I originally tried to mitm it but that's not possible since the router verifies the acs server ssl certificate. You have to enable ssh using tr-069 on the WAN side(there's a built in remote activate-able root ssh backdoor), I set up a local genieacs server to do that. Link found when searching the model number WPCS7542E A1ĭocumentation: 450337 CS7542/CS7522 Product Brief Current method of getting a root console ( creds) Most of the original info here is from the binwalk issue thread Verizon open source code for adherence to the gpl licence The final goal of this project is to be able to port and install openwrt/lede to the FIOS-G1100, a router that stock firmware is awful for All the current information on reverse engineering the FIOS-G1100 Quantum Gateway router ![]()
