Summary
A relative path traversal vulnerability (CWE-23) in Fortinet FortiOS (7.2.0–7.2.3, 7.0.0–7.0.8, 6.4.0–6.4.11, 6.2.0–6.2.12) and FortiProxy (7.2.0–7.2.1, 7.0.0–7.0.7, 2.0.0–2.0.11, 1.2, 01.02, 1.1, 01.01) allows privileged VDOM administrators to escalate to super admin via crafted CLI requests.
Risk Assessment
A VDOM administrator can gain full administrative control of the FortiGate or FortiProxy device, potentially altering security configuration and intercepting network traffic.
Recommendation
Update FortiOS and FortiProxy to patched versions and limit the number of VDOM administrator accounts.
