CVE-2023-34991Network attack vector

Unauthenticated code execution via SQL injection

Published Nov 14, 2023 · Updated Dec 16, 2025

SQL injection in affected Fortinet FortiWLM releases allows remote attackers to execute unauthorized code via a crafted HTTP request. FortiWLM processes attacker-controlled special elements from the request in an SQL command without neutralization; Fortinet has not identified the endpoint or parameter. No authentication or user interaction is required, and successful exploitation permits code or command execution affecting stored data and service operation.
