Account takeover via misbound FIDO authenticator enrollment
Published Apr 3, 2024 · Updated Aug 21, 2024
Improper authentication in Veridium Software VeridiumAD before 3.5.0 allows remote attackers to take over victim accounts via WebAuthn. The WebAuthn enrollment flow associates an attacker-controlled FIDO authenticator with a victim account without authenticating the attacker as that account owner. Exploitation requires internal network access, successful enrollment verification, and permission to enroll a FIDO key; the registered key then grants control of the victim account.
