CVE-2023-31756 is a command injection vulnerability in the administrative web portal of TP-Link Archer VR1600V devices running firmware versions <= 0.1.0.0.9.1 v5006.0 Build 220518 Rel.32480n. Authenticated attackers with administrator access can exploit the 'X_TP_IfName' parameter to inject arbitrary commands, resulting in the execution of operating system-level commands on the device.

This repository contains a Python proof-of-concept exploit for CVE-2023-31756, a remote command execution vulnerability affecting TP-Link Archer VR1600V V1/V2 routers. The main file, 'CVE-2023-31756-Longbow.py', is a standalone exploit script that requires the attacker to have authenticated access to the router's web interface (JSESSIONID cookie). The script interacts with the router's HTTP CGI endpoints to manipulate WAN interface objects and injects a command (by default, starting a telnet daemon with a root shell) via the 'X_TP_IfName' parameter. If successful, the attacker can connect to the router's telnet port (23) and obtain a root shell. The exploit allows for custom commands (up to 13 characters) to be injected as well. The repository also includes a README.md with detailed usage instructions and context. No framework is used; the exploit is a standalone Python script targeting a specific router model and firmware version.
