FortiWeb CVE-2025-64446: Exploited Unauthenticated Takeover
Any FortiWeb still below the fixed builds with its web GUI reachable from the internet should be presumed compromised and rebuilt, not just patched.
Must act: Operators of FortiWeb 7.0 through 8.0.1 (and unsupported 6.x) appliances, especially with HTTP/HTTPS management exposed.
Can relax: FortiAppSec Cloud customers, organizations without FortiWeb, and FortiWeb fleets that were upgraded in November 2025 and audited for rogue admins.
- Upgrade to FortiWeb 8.0.2, 7.6.6, 7.4.11, 7.2.12 or 7.0.12 or later
- Until upgraded, disable HTTP/HTTPS administrative access on internet-facing interfaces
- Audit local administrator accounts and remove any you did not create
