This repository provides a proof-of-concept exploit for CVE-2018-0886, a vulnerability in Microsoft's CredSSP protocol used in RDP authentication. The exploit consists of Python scripts and installation files. The main script, 'bin/gen_cmd.py', generates a malicious certificate and private key that embed an attacker-supplied command. The installation script ('install/install.sh') sets up the required environment, including a patched version of OpenSSL (with the patch provided in 'install/openssl_diff_file.diff') and necessary Python dependencies. The exploit is used in conjunction with a forked version of the 'rdpy' project to perform a man-in-the-middle attack on RDP sessions, allowing the attacker to execute arbitrary commands on the target Windows system. The README provides detailed setup and usage instructions, including how to generate the malicious certificate and run the MITM attack. The exploit targets unpatched Windows systems vulnerable to CVE-2018-0886 and requires the attacker to have access to a valid server authentication certificate.
