Loading vulnerability…
CVE-2019-9624 is a remote code execution vulnerability in Webmin 1.900 and earlier. Authenticated users with access to the 'Java file manager', 'Upload and Download', and 'Running Processes' features can upload a crafted .cgi file via the /updown/upload.cgi endpoint. The uploaded file can then be executed, allowing arbitrary commands to be run as root. The vulnerability is exploitable over HTTP/HTTPS and has a public Metasploit module (exploit/unix/webapp/webmin_file_upload_exec).

This repository contains an exploit for CVE-2019-9624, an authenticated remote code execution vulnerability in Webmin 1.900. The exploit consists of a single Python script (exploit.py) and a detailed README.md. The script automates the process of logging into a Webmin instance using provided credentials, then sends a specially crafted multipart/form-data POST request to the /shell/index.cgi endpoint to execute arbitrary system commands as root. The output of the command is parsed and displayed to the user. The exploit requires valid administrative credentials and network access to the Webmin service (typically on port 10000). The code is operational and allows the attacker to specify any command to be executed, making it a practical post-authentication RCE tool. No hardcoded payloads are present; the command is supplied at runtime. The repository is well-structured, with clear separation between documentation and exploit code.
This repository contains a single Metasploit module (webmin_upload_exec.rb) that exploits an authenticated remote command execution vulnerability in Webmin versions 1.900 and below (CVE-2019-9624). The exploit targets the 'Upload and Download' module, allowing an authenticated user to upload a malicious Perl CGI script and execute arbitrary commands as root. The module requires valid Webmin credentials and can optionally guess the upload directory if the user lacks 'proc' privileges. The exploit is weaponized, supporting customizable command payloads, and leverages several Webmin HTTP(S) endpoints for authentication, file upload, and payload execution. The code is written in Ruby and is structured as a standard Metasploit exploit module, making it easy to use within the Metasploit framework.
