Monsta FTP versions 2.11 and earlier contain a vulnerability that allows unauthenticated arbitrary file uploads. This flaw enables attackers to execute arbitrary code by uploading a specially crafted file from a malicious (S)FTP server.

This detection template works by sending a GET request to the target URL, checking if the response contains <title>Monsta FTP with a 200 status code, extracting the version from the title tag using regex, and then comparing it against version 2.11 to identify vulnerable instances.
