Name of the Vulnerable Software and Affected Versions SourceCodester Online Course Registration version 1.0

Description A File Upload issue allows remote attackers to achieve Remote Code Execution (RCE) on the hosting webserver by uploading a crafted PHP web-shell that bypasses the image upload filters. An attack uses the "my-profile.php" endpoint with the photo parameter.

Recommendations For version 1.0, consider disabling the file upload feature or restricting the types of files that can be uploaded to prevent exploitation until a fix is available. Restrict access to the "my-profile.php" endpoint to minimize the risk of exploitation. Avoid using the photo parameter in the affected endpoint until the issue is resolved.
