medium Nessus Plugin ID 241567

Language:

Synopsis

Fortinet Firewall is affected by a privilege escalation.

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-25-026 advisory.

 - A heap-based buffer overflow in Fortinet FortiOS 7.6.0 through 7.6.2, FortiOS 7.4.0 through 7.4.7, FortiOS 7.2.4 through 7.2.12 allows an attacker to escalate its privileges via a specially crafted CLI command (CVE-2025-24477)

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

Solution

For 7.4.x, upgrade to Fortigate version 7.4.8 or later. For 7.6.x, upgrade to Fortigate version 7.6.3 or later.
