Vvveb CMS 1.0.8.2 contains a remote code execution vulnerability in its media upload handler that allows authenticated attackers to execute arbitrary operating system commands by uploading a PHP webshell with a .phtml extension. Attackers can bypass the extension deny-list and upload malicious files to the publicly accessible media directory, then request the file over HTTP to achieve full server compromise.
