Technical details

An arbitrary file upload vulnerability exists in UniSharp Laravel File Manager v2.0.0-alpha7 and v2.0. The flaw is located in the upload endpoint, where the application fails to properly validate file extensions when the 'type' parameter is set to 'Files'. An authenticated attacker can send a multipart/form-data POST request containing a PHP shell. By specifying a 'working_dir' and accessing the uploaded file via its web-reachable path, the attacker can achieve remote code execution (RCE) with the privileges of the web server user. Public exploits are available for this vulnerability.
