Detection Guidance

This vulnerability can be detected by attempting to access private files through manipulation of the 'id' parameter in the download request to process.php. A simple test command would be to send a GET request to the endpoint `/process.php?do=download&id=[file_id]` with different file IDs to check if unauthorized files can be downloaded. For example, using curl: `curl -v "http://targetsite/process.php?do=download&id=1"` and changing the id value to see if files belonging to other users are accessible without authentication. [1, 2]

Mitigation Strategies

Immediate mitigation steps include restricting access to the download functionality by implementing proper authorization checks on the 'id' parameter to ensure users can only download their own files. Until a patch is applied, consider disabling the download feature or restricting access to authenticated and authorized users only. Monitoring and logging download requests for suspicious activity is also recommended. [2]
