Detection & IOCs extracted from sources · hover to see the quote

• → Monitor for successful authentication to FortiGate using credentials belonging to admin accounts that have been deleted in FortiManager — the vulnerability allows deleted accounts to persist and remain usable for access. ↗
• → Audit FortiGate admin account lists against FortiManager's current active account list; any FortiGate admin account that no longer exists in FortiManager but can still authenticate represents exploitation of this vulnerability. ↗

• · Affected versions are FortiManager 6.4.12 through 7.4.0; verify your FortiManager version falls within this range before applying detections or mitigations. ↗
• · The vulnerability is rooted in CWE-672 (Operation on a Resource after Expiration or Release), meaning deleted admin accounts are not properly invalidated — access control enforcement on FortiGate does not reflect account deletion events from FortiManager. ↗
