This repository contains an exploit for CVE-2022-25060, a remote command execution vulnerability in the TP-Link WR840N router. The main exploit script (CVE-2022-25060.py) is written in Python and requires the attacker's TFTP server (lhost), the target router's IP, and valid admin credentials. The script crafts a malicious request to the router's /cgi?2 endpoint, injecting a command to download a MIPSLE reverse shell binary (reverse_shell_mipsle.c, to be compiled and hosted by the attacker) via TFTP, set it as executable, and run it. The exploit then triggers the vulnerability via the /cgi?7 endpoint. The reverse shell binary, once executed on the router, connects back to the attacker's machine, providing a remote shell. The repository structure is straightforward: the Python exploit script, a C source file for the reverse shell (to be compiled for MIPSLE), and a brief README. The exploit is operational, requiring some setup (TFTP server, compilation of the payload) but provides a working remote shell if successful.
