CVE-2022-40679

Authenticated command execution via crafted command arguments

Published Apr 11, 2023 · Updated Oct 23, 2024

OS command injection in Fortinet FortiADC, FortiDDoS, and FortiDDoS-F allows local users to execute unauthorized commands. The GUI log and report module fails to neutralize shell-significant elements in crafted arguments supplied to existing commands. An authenticated low-privilege appliance session is required; Fortinet does not identify the exposed commands or their execution context.
