Fortinet FortiWeb v8.0.1 - Auth Bypass
Fortinet FortiWeb v8.0.1 - Auth Bypass
AI Analysis
Technical Summary
Fortinet FortiWeb version 8.0.1 is affected by an authentication bypass vulnerability that allows an attacker to circumvent authentication mechanisms. Exploit code written in Perl has been published, demonstrating the feasibility of exploiting this vulnerability. No details on affected sub-versions or patch availability are provided.
Potential Impact
Successful exploitation could allow an attacker to bypass authentication controls on FortiWeb v8.0.1, potentially gaining unauthorized access to the system or its management interface. The exact impact depends on the privileges granted post-bypass but could lead to unauthorized configuration changes or access to sensitive data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, monitor vendor communications for updates and consider implementing compensating controls such as restricting access to FortiWeb management interfaces to trusted networks.

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!
