Administrator-to-root escalation via sudo abuse
Published May 10, 2021 · Updated Oct 25, 2024
Privilege escalation in Fortinet FortiNAC 8.8.1 and earlier allows remote authenticated users to gain root access through sudo. Fortinet identifies abused sudo privileges as the mechanism but has not disclosed the permitted command, sudoers rule, or input handling that enables the escalation. Administrative access is required, and successful exploitation converts that product-level authority into root control of the FortiNAC appliance.
