Loading vulnerability…
In Webmin through version 1.920, the rpc.cgi script is vulnerable to authenticated remote code execution. The vulnerability arises from the use of the unserialise_variable function, which makes an unsafe eval call on user-supplied data. An authenticated attacker can exploit this by sending a crafted object name, leading to arbitrary code execution on the server.

This repository contains a Python exploit script (CVE-2019-15642.py) and a README for CVE-2019-15642, an authenticated remote code execution vulnerability in Webmin (<=1.930). The exploit requires valid Webmin credentials and targets the /rpc.cgi endpoint, sending a crafted POST request with a malicious payload that executes arbitrary system commands on the server. The script prompts the user for credentials, encodes them in Base64 for HTTP Basic Authentication, and allows the attacker to specify any command to run on the target. The README provides usage instructions, example output, and setup guidance for a vulnerable Webmin instance using Docker. The main attack vector is network-based, requiring access to the Webmin management interface. The only code file is the exploit script, written in Python, and the repository is focused solely on demonstrating and exploiting this specific vulnerability.
