This repository provides a Python proof-of-concept exploit for CVE-2017-11519, targeting TP-Link Archer C9 routers. The exploit consists of two main code files: 'tplink.py' (the main exploit script) and 'utils.py' (helper functions for cryptography and random number generation). The exploit automates the process of resetting the admin password by predicting the router's verification code using a PRNG seeded from the router's HTTP Date header. After resetting the password, it logs in as admin and exploits a command injection vulnerability in the USB sharing feature by creating a new user account with a crafted username and password. This allows the attacker to execute arbitrary shell commands on the router, such as fetching and executing a reverse shell from a provided URL. The exploit interacts with the router's web interface over HTTP, targeting endpoints under '/cgi-bin/luci/'. The repository is operational and provides a working exploit chain for both admin password reset and remote code execution.
