Technical details

A vulnerability exists in ManageEngine ADSelfService Plus, RecoveryManager Plus, M365 Manager Plus, and ADAudit Plus when deployed as integrated components within ManageEngine AD360. The root cause is the use of insufficiently random values (CWE-330) and predictable identifiers (CWE-340) during the generation of Single Sign-On (SSO) tickets. An unauthenticated remote attacker can predict valid SSO tickets to bypass authentication (CWE-287) and obtain a targeted user's identity and role information. This leads to full account takeover. The vulnerability is addressed in ADSelfService Plus 6529, RecoveryManager Plus 6321, M365 Manager Plus 4817, and ADAudit Plus 8703.
