Xymon useradm Command Execution
Posted on 12 July 2019
This Metasploit module exploits a command injection vulnerability in Xymon versions before 4.3.25 which allows authenticated users to execute arbitrary operating system commands as the web server user. When adding a new user to the system via the web interface with useradm.sh, the user's username and password are passed to htpasswd in a call to system() without validation. This module has been tested successfully on Xymon version 4.3.10 on Debian 6.
