CVE-2024-21758

Privileged code execution via crafted CLI commands

Published Jan 14, 2025 · Updated Feb 18, 2025

Stack overflow in Fortinet FortiWeb 7.2.0 through 7.2.7 and 7.4.0 through 7.4.1 allows local users to execute code via CLI. Fortinet has not disclosed which CLI command handler copies attacker-controlled data beyond a stack buffer. The user must already hold privileged CLI access and bypass FortiWeb stack protections; successful exploitation grants arbitrary code execution.
