Technical details
This vulnerability is an authentication bypass in Delinea's FIDO2 credential management. The root cause appears to be insufficient validation or authorization checks during FIDO2 credential registration, allowing an attacker to associate an attacker-controlled credential with a target account. Once registered, the attacker can authenticate as the target user. The attack vector and preconditions are not fully detailed in the advisory, but the issue is specific to on-premises deployments. Patches or mitigations should be available from Delinea's security advisory page.
