| Title | CMS Made Simple 2.2.21 Arbitrary File Upload |
|---|
| Description | CMS Made Simple Version 2.2.21 upload-photo.php file contains a critical arbitrary file upload vulnerability. There is a lack of proper validation for the extracted files from compressed archives. Attackers can bypass restrictions to upload compressed files containing malicious PHP scripts and extract them after upload. The uploaded files are stored in a publicly accessible directory, and these scripts can then be accessed and executed via a web browser, enabling the attacker to fully compromise the server environment. |
