CVE-2018-11714 is an authentication-bypass vulnerability in the web management interfaces of TP-Link TL-WR840N v5 firmware 0.9.1 3.16 v0001.0 Build 170608 Rel.58696n and TL-WR841N v13 firmware 0.9.1 4.16 v0001.0 Build 170622 Rel.64334n. Improper session handling for CGI resources permits unauthenticated requests when the attacker supplies a Referer header indicating the router's main management frame. This bypass applies to actions exposed through the CGI directory or CGI files.

This repository contains a proof-of-concept exploit for CVE-2018-11714, targeting TP-Link TL-WR840N routers. The exploit leverages improper session handling in the router's web interface, specifically for endpoints under /cgi/. By sending a GET request to the /cgi/conf.bin endpoint with a crafted Referer header, the script bypasses authentication and downloads the router's configuration file. The script then processes the file by removing the first 144 bytes and decrypts the remainder using DES-ECB with a hardcoded key, outputting the plaintext configuration. The repository consists of a README.md describing the vulnerability and a single Python script (poc.py) implementing the exploit. The attack vector is network-based, requiring access to the router's web interface. Several file and HTTP endpoints are fingerprintable, including the specific URLs and output files used in the exploit process.
