Name of the Vulnerable Software and Affected Versions Open eClass versions prior to 4.2

Description The Open eClass platform, previously known as GUnet eClass, is a course management system. A security issue exists where an unauthenticated remote attacker can access personal files belonging to other users. This is possible by directly requesting predictable user identifiers, exploiting an Insecure Direct Object Reference (IDOR). An IDOR occurs when an application uses user-supplied input to directly access objects based on that input. In this case, the application fails to properly validate the user's authorization before granting access to files. The user identifiers are predictable, allowing attackers to enumerate and access files they should not have permission to view.

Recommendations Update to version 4.2 or later.
