CVE-2022-26116Network attack vector

Authenticated command execution via SQL injection

Published May 11, 2022 · Updated Oct 25, 2024

SQL injection in Fortinet FortiNAC affected releases allows remote authenticated users to execute unauthorized code or commands. Fortinet states that multiple crafted string parameters are not properly neutralized before use in SQL commands, but it does not identify the affected component, endpoints, or parameter names. Exploitation requires high-privilege access to a network-facing interface and no user interaction; successful command execution can compromise the appliance.
