V-CMS PHP File Upload and Execute

Description

This module exploits a vulnerability found on V-CMS's inline image upload feature. The problem is due to the inline_image_upload.php file not checking the file type before saving it on the web server. This allows any malicious user to upload a script (such as PHP) without authentication, and then execute it with a GET request. The issue is fixed in 1.1 by checking the extension name. By default, 1.1 only allows jpg, jpeg, png, gif, bmp, but it is still possible to upload a PHP file as one of those extension names, which may still be leveraged in an attack.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
