op5 Portal Arbitrary Command Execution

critical Nessus Plugin ID 57576


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 1.6.2. As such, it contains a flaw in the 'license.php' script that allows a remote, unauthenticated attacker to run arbitrary commands with the privileges of the web user simply by enclosing them in backticks in the timestamp field.


Upgrade op5 Portal to version 1.6.2 or later.
