Unauthenticated FGFM daemon crash via buffer over-read
Published May 28, 2025 · Updated May 28, 2025
Buffer over-read in affected FortiOS releases allows remote attackers to crash the FGFM daemon through a crafted network request. The FGFM daemon reads beyond a buffer boundary while processing the request; Fortinet has not disclosed the exact parsing operation or request field. No authentication is required, but exploitation depends on rare conditions outside attacker control and only interrupts the FGFM service.
