Fortinet FortiWeb v8.0.1 – Auth Bypass
# Titles:Fortinet FortiWeb v8.0.1 - Auth Bypass # Author: nu11secur1ty # Date: 11/15/2025 # Vendor: https://www.fortinet.com/ # Software: v8.0.1 # Reference: https://nvd.nist.gov/vuln/detail/CVE-2025-64446 ## Description: CVE-2025-64446 is a critical path traversal vulnerability affecting multiple versions of Fortinet FortiWeb, a Web Application Firewall (WAF) used to protect web applications and APIs. The vulnerability allows an unauthenticated remote attacker to send specially crafted HTTP/HTTPS requests that may result in administrative access bypass on vulnerable FortiWeb systems. ## Severity - CVSS v3.1 Score: 9.8 (Critical) - Attack Vector: Network - Privileges Required: None (Unauthenticated) - User Interaction: None - Impact: High (Authentication bypass, configuration exposure, potential full administrative access) ## Affected Products & Versions The following FortiWeb versions are confirmed vulnerable: | Product | Affected Versions | |--------|--------------------| | FortiWeb 8.0.x | 8.0.0 – 8.0.1 | | FortiWeb 7.6.x | 7.6.0 – 7.6.4 | | FortiWeb 7.4.x | 7.4.0 – 7.4.9 | | FortiWeb 7.2.x | 7.2.0 – 7.2.11 | | FortiWeb 7.0.x | 7.0.0 – 7.0.11 | ## Fixed Versions Fortinet has released patched versions that fully address CVE-2025-64446: | Product | Fixed Version | |---------|----------------| | FortiWeb 8.0.x | 8.0.2 or later | | FortiWeb 7.6.x | 7.6.5 or later | | FortiWeb 7.4.x | 7.4.10 or later | | FortiWeb 7.2.x | 7.2.12 or later | | FortiWeb 7.0.x | 7.0.12 or later | ## Technical Description The vulnerability stems from insufficient path normalization in HTTP/HTTPS request handling, allowing externally controlled paths to bypass directory restrictions. This may result in: - Unauthorized access to backend administrative endpoints - Exposure of sensitive configuration - Potential manipulation of management interfaces ## Impact If successfully exploited, attackers may achieve: - Authentication bypass - Administrative access - Ability to view/modify configuration - Possible service disruption ## Mitigation If immediate patching is not possible: 1. Disable public HTTP/HTTPS administrative access. 2. Restrict admin interfaces to trusted internal networks. 3. Use firewall rules to limit admin-port access. 4. Monitor logs for traversal-like patterns. ## Remediation **Upgrade to the nearest patched version as soon as possible.** ## Disclosure Timeline | Date | Event | |------|--------| | 2025-XX-XX | Vulnerability discovered | | 2025-XX-XX | Vendor notified | | 2025-XX-XX | Patch development | | 2025-XX-XX | Advisory published | | 2025-XX-XX | CVE assigned | # STATUS: HIGH - CRITICAL [+]Payload: ``` No!
