CVE-2024-55594Network attack vector

Unauthenticated code execution via malformed HTTP requests

Published Mar 14, 2025 · Updated Mar 14, 2025

Improper handling of invalid HTTP structures in Fortinet FortiWeb allows remote attackers to execute unauthorized code or commands. Fortinet states that crafted HTTP/S requests trigger improper handling of syntactically invalid structures, but it has not disclosed the affected parser or erroneous operation. The network attack requires no authentication or user interaction, while high attack complexity constrains reachability.
