    Field note · TruePositive EditorialCurated

    A pre-authentication path traversal in the FortiOS SSL VPN lets an attacker read system files, including session files that hold usernames and passwords in plain text. Years after disclosure, attackers were still dumping and reselling credential lists from unpatched FortiGate devices, which is why this keeps causing breaches.

    Who is affected: FortiGate SSL VPN on vulnerable FortiOS versions.

    Very important: patching does not undo a past leak. If your device was exposed and unpatched, treat those VPN credentials as already stolen.

    Commonly flagged by: Nessus, Qualys, Rapid7.

    Remediation · TruePositive EditorialCurated

    Patch FortiOS to a fixed version, then reset all VPN user passwords, because leaked credentials stay valid after patching. Turn on multi-factor authentication for the VPN so a stolen password alone is not enough, and review logs for earlier access.
