AI description

Automated description summarized from trusted sources.

CVE-2025-64446 is a relative path traversal vulnerability affecting Fortinet FortiWeb versions 8.0.0 through 8.0.1, 7.6.0 through 7.6.4, 7.4.0 through 7.4.9, 7.2.0 through 7.2.11, and 7.0.0 through 7.0.11. It can be exploited by sending crafted HTTP or HTTPS requests. This vulnerability allows remote, unauthenticated attackers to gain administrative access to the web application firewall appliances. Specifically, the vulnerability can be exploited by sending an HTTP POST request to `/api/v2.0/cmdb/system/admin%3f/../../../../../cgi-bin/fwbcgi` with a payload designed to create an administrative account. Successful exploitation allows an attacker with no prior access to gain administrator-level access to the FortiWeb Manager panel and websocket command-line interface.

This exploit was picked up by Defused as early as October 2nd where it was thought to be a variant of CVE-2022-40684. However, Fortinet have confirmed that this is a new vulnerability and have assigned this CVE to the vulnerability. This vulnerability takes advantage of both a path traversal (/api/v2.0/cmdb/system/admin%3f/../../../../../cgi-bin/fwbcgi) and an auth bypass via the cookie CGIINFO.

Fortinet offer little information within their disclosure, and until today there was no patching information as mentioned within watchTowr's article. The infosec community has collated some IOC's which can be found here. This vulnerability has been actively exploited to create a new administrative user, any instances of Fortiweb that have exposed the web GUI to the internet should be considered compromised.
