Name of the Vulnerable Software and Affected Versions Ulearn version a5a7ca20de859051ea0470542844980a66dfc05d

Description The issue allows an attacker with administrator permissions to obtain remote code execution on the server through the image upload functionality. This occurs because the application does not validate that the uploaded image is actually an image.

Recommendations For Ulearn version a5a7ca20de859051ea0470542844980a66dfc05d, consider disabling the image upload functionality until a patch is available to prevent remote code execution. Restrict access to the image upload feature to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
