Details

This affects versions of the package unisharp/laravel-filemanager before 2.6.2. The upload() function does not sufficiently validate the file type when uploading.

An attacker may be able to reproduce the following steps:

  1. Install a package with a web Laravel application.
  2. Navigate to the Upload window
  3. Upload an image file, then capture the request
  4. Edit the request contents with a malicious file (webshell)
  5. Enter the path of file uploaded on URL - Remote Code Execution

Note: Prevention for bad extensions can be done by using a whitelist in the config file(lfm.php). Corresponding document can be found in here.
