medium Nessus Plugin ID 179503

Language:

Synopsis

Fortinet Firewall is missing one or more security-related updates.

Description

The version of Fortigate installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the FG-IR-23-149 advisory.

 - A stack-based buffer overflow vulnerability [CWE-121] in Fortinet FortiOS before 7.0.3 allows a privileged attacker to execute arbitrary code via specially crafted CLI commands, provided the attacker were able to evade FortiOS stack protections. (CVE-2023-29182)

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

Solution

Please upgrade to FortiOS version 6.4.15/7.0.4/7.2.0/7.4.0 or later.
