Fortinet FortiOS Privilege Escalation (FG-IR-20-131)

high Nessus Plugin ID 156783

Language:

Synopsis

The remote host is affected by a privilege escalation vulnerability.

Description

The remote host is running a version of FortiOS prior or equal to 6.0.12, 6.2.x prior or equal to 6.2.9, 6.4.x prior or equal to 6.4.6, 7.0.0 or FortiOS-6K7K version prior or equal to 6.2.6, 6.4.2. It is, therefore, affected by a privilege escalation vulnerability in FortiOS autod daemon, which may allow an authenticated low-privileged attacker to escalate their privileges to super_admin via a specific crafted configuration of fabric automation CLI script and auto-script features.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

See vendor advisory.
