Security Summary

CVE-2025-24472 is an Authentication Bypass Using an Alternate Path or Channel vulnerability (CWE-288) with a CVSS v3.1 base score of 8.1 (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H). It affects FortiOS versions 7.0.0 through 7.0.16 and FortiProxy versions 7.2.0 through 7.2.12 as well as 7.0.0 through 7.0.19.

A remote unauthenticated attacker with prior knowledge of the serial numbers of upstream and downstream devices can exploit the vulnerability if Security Fabric is enabled. By sending crafted CSF proxy requests, the attacker may gain super-admin privileges on the downstream device.

MITRE ATT&CK Enterprise Techniques

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
Why these techniques?

The vulnerability is a remote unauthenticated authentication bypass in FortiOS/FortiProxy (public-facing network security devices) via crafted requests when Security Fabric is enabled, directly enabling exploitation of a public-facing application for initial access and admin privileges.
