critical Nessus Plugin ID 57578


The remote web server hosts a PHP application that is vulnerable to arbitrary command execution.


The version of op5 Config hosted on the remote web server is earlier than 2.0.3. As such, it contains a flaw on its welcome page that allows a remote, unauthenticated attacker to run arbitrary commands with root privileges simply by enclosing them in backticks in the password field.


Upgrade op5 Config to version 2.0.3 or later.
