Description

Chamilo LMS is a free software e-learning and content management system. In versions prior to <= v1.11.24 a webshell can be uploaded via the bigload.php endpoint. If the GET request parameter `action` is set to `post-unsupported` file extension checks are skipped allowing for attacker controlled .php files to be uploaded to: `/main/inc/lib/javascript/bigupload/files/` if the `/files/` directory already exists - it does not exist by default.

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.
