This repository contains a working exploit for CVE-2021-31760, targeting Webmin version 1.973. The exploit leverages a CSRF vulnerability in the /proc/run.cgi endpoint to achieve remote command execution as root. The main file, RCE_eXploit.py, is a Python script that guides the user through entering the target Webmin URL, the attacker's IP and port, and the desired reverse shell type (Bash, PHP, Python, Perl, or Ruby). It then generates a CSRF proof-of-concept HTML file (CSRF_POC.html) that, when visited by a logged-in Webmin admin, will send a POST request to the vulnerable endpoint with a reverse shell payload. The script also provides a function to start a netcat listener for the incoming shell. The README.md provides context, usage instructions, and references to the vulnerability and affected product. The exploit is operational and provides a customizable reverse shell payload, but is not part of a larger framework.
This repository contains a Python exploit script (RCE_eXploit.py) and a README.md for CVE-2021-31760, a CSRF-to-RCE vulnerability in Webmin 1.973. The exploit automates the creation of a malicious CSRF HTML file (CSRF_POC.html) that, when visited by a Webmin admin, sends a POST request to the /proc/run.cgi endpoint on the target Webmin server. The attacker can select from several reverse shell payloads (Bash, PHP, Python, Perl, Ruby), which are injected as the 'cmd' parameter in the POST request. The script also offers to start a netcat listener for the attacker's reverse shell. The README provides context, usage instructions, and references. The main attack vector is remote (network) via browser-based CSRF, targeting authenticated Webmin administrators. The only code file is RCE_eXploit.py, which is the entry point and contains all exploit logic.
