Author: Laxmikant sharad Hire.
Fortinet has issued an urgent security patch for a critical SQL injection vulnerability affecting its FortiWeb web application firewall, tracked as CVE-2025-25257. With a CVSS score of 9.6, this flaw demands immediate attention from users and administrators.
🔍 What Is CVE-2025-25257?
The vulnerability stems from improper neutralization of SQL elements (CWE-89) in FortiWeb’s Fabric Connector component, particularly in the function get_fabric_user_by_token, which interacts with various API endpoints:
/api/fabric/device/status/api/v[0-9]/fabric/widget/[a-z]+/api/v[0-9]/fabric/widget
This security gap allows unauthenticated attackers to inject arbitrary SQL commands via specially crafted HTTP/HTTPS requests using a manipulated Bearer token in the Authorization header.
⚙️ Impacted FortiWeb Versions
The following versions are vulnerable and must be upgraded:
| Affected Version Range | Secure Version to Upgrade To |
|---|---|
| 7.6.0 – 7.6.3 | 7.6.4 or higher |
| 7.4.0 – 7.4.7 | 7.4.8 or higher |
| 7.2.0 – 7.2.10 | 7.2.11 or higher |
| 7.0.0 – 7.0.10 | 7.0.11 or higher |
Security researcher Kentaro Kawane (GMO Cybersecurity) was credited for the discovery. His prior reports also uncovered major flaws in Cisco ISE products.
🛡️ How the Exploit Works
Attackers exploit the flawed function to directly inject harmful SQL queries into the database without sanitization. This opens the door to:
- Unauthorized data access
- Database manipulation
- Remote Code Execution via
SELECT ... INTO OUTFILEand Python execution
🔧 Fortinet’s Fix and Recommendations
To remediate the issue, Fortinet has:
- Replaced vulnerable query strings with prepared SQL statements
- Issued patches for all affected versions
Until patches are deployed, users should disable the HTTP/HTTPS administrative interface as a precaution.
⚠️ Why It Matters
Fortinet products have been actively targeted by threat actors in past breaches. Delaying updates could result in serious risks like data theft or system compromise.
