Authenticated user account impersonation

Published Aug 28, 2024 · Updated Oct 6, 2025

Improper privilege management in NetIQ Access Manager before 5.0.4.1 and before 5.1 allows remote authenticated users to impersonate accounts. OpenText has not published the affected MFA configuration, vulnerable component, or privilege-assignment operation that enables impersonation. Exploitation requires valid access, user interaction, and the undisclosed MFA configuration; successful abuse compromises the impersonated account's confidentiality and integrity.
