CVE-2023-34986Network attack vector

Authenticated command execution via HTTP GET parameters

Published Oct 10, 2023 · Updated Sep 19, 2024

OS command injection in Fortinet FortiWLM 8.5.0 through 8.5.4 and 8.6.0 through 8.6.5 allows remote authenticated users to run commands. The web interface passes crafted HTTP GET parameter values into an operating-system command without neutralizing command syntax. Low-privileged access is required; Fortinet has not disclosed the affected endpoint or parameter, and successful injection permits code execution with the service's privileges.
