Impact

Critical risk (CVSS 9.8, EPSS 88.2%). FortiWeb is a WAF protecting web applications. Compromising the WAF allows attackers to bypass all web application security controls and access protected applications.

Exploit ScenarioDerived

An attacker sends crafted requests with path traversal to FortiWeb, reaching admin command endpoints. Administrative command execution provides full control of the WAF, enabling disabling of security policies and accessing protected backend applications.

Emergency Immediate action required. Why: CRITICAL + in CISA KEV (actively exploited), no patch available.
Exploited in the wild (CISA KEV) No patch listed yet 88.2% exploitation probability (EPSS)
