This repository contains operational exploit code for CVE-2023-26067, a command injection vulnerability affecting Lexmark printers. The main exploit script (CVE-2023-26067.py) enables attackers to check for vulnerability, execute arbitrary commands, exfiltrate the printer's credential database (auth.db), and dump both LDAP and local credentials. It sets up a local HTTP server to receive exfiltrated files and a TCP listener to capture command output. The Print4Shell.py script provides a reverse shell exploit, using socat to connect back to the attacker's machine. BitConductor.py is a utility to play music on the printer's beeper by generating specific command sequences. The README.md provides detailed usage instructions, technical background, and mitigation advice. The exploit targets the /cgi-bin/fax_change_faxtrace_settings endpoint on Lexmark printers and leverages network access to achieve remote code execution and credential theft. The code is written in Python and is operational, providing real-world attack capabilities against unpatched devices.
