Summary

ATutor is vulnerable to authentication bypass. Although a token validation check is present in the auto-login functionality, the values required for token validation remain uninitialized in certain code paths. An unauthenticated attacker who can determine a user's identifier and registration timestamp can generate a valid token and authenticate as an existing user, including administrator, without knowing the password. The product is no longer actively supported and the vulnerabilities have not been fixed; only version 2.2.4 was tested and confirmed as vulnerable.

Risk Assessment

The risk is critical because an attacker can gain full access to the system as an administrator, which could lead to complete compromise of confidentiality, integrity, and availability of data.

Recommendation

It is recommended to immediately disable or replace ATutor with a more secure solution, as the product is unsupported and no patches are available. If necessary, restrict access to the system and monitor logs for unusual activity.
