Summary
An improper authorization vulnerability (CWE-285) in Fortinet FortiOS and FortiProxy allows an authenticated attacker to access static files of other VDOMs via crafted HTTP or HTTPS requests. Affects multiple versions of FortiOS (7.4.0-7.4.1, 7.2.0-7.2.8, 7.0.0-7.0.11) and FortiProxy (7.4.0-7.4.8, 7.2, 7.0, 2.0).
Risk Assessment
An attacker with valid credentials can access static files belonging to other VDOMs, potentially leading to information disclosure. This may compromise data confidentiality in multi-domain environments.
Recommendation
Update FortiOS and FortiProxy to the latest versions containing the fix. Restrict access to management interfaces and monitor for unusual HTTP/HTTPS requests.
