A vulnerability in Light0011 CMS version c774dce31c6df0055568a8d5c53d964d99be199d/f72cf46f601efb2a0618c3814cc2f61380b38930 has been identified. The issue arises in the Uploadify component, specifically within the 'check-exists.php' file. The vulnerability is related to the 'file_exists' function, where the 'filename' argument can be manipulated to expose file and directory information. This issue can be exploited remotely, and the public exploit is available.
It is recommended to remove the legacy 'check-exists.php' endpoint if it is not in use. If it is needed, implement measures such as using server-generated file identifiers, normalizing file paths to prevent traversal attacks, ensuring that canonical paths remain within the intended directory, and requiring proper authorization before access.
