CVE-2022-33873

Unauthenticated shell commands via console login injection

Published Oct 10, 2022 · Updated Oct 25, 2024

OS command injection in Fortinet FortiTester console login allows physically proximate attackers to execute commands in the underlying shell. The login path fails to neutralize shell metacharacters in attacker-controlled console input before invoking an operating-system command. Access requires the appliance console but no authenticated account; successful exploitation runs commands with the affected process's privileges.
