CVE-2025-11690
📋 TL;DR
An Insecure Direct Object Reference (IDOR) vulnerability in the vehicleId parameter allows attackers to bypass authorization and access sensitive data from other users' vehicles. This affects users of the vulnerable vehicle management system, exposing their GPS locations, encryption keys, and vehicle statistics. The vulnerability stems from missing server-side authorization checks.
💻 Affected Systems
- Vehicle management system referenced in NCSC advisory
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Mass data breach exposing real-time GPS locations, encryption keys, and sensitive vehicle data for all users, enabling physical tracking, vehicle theft, or manipulation of vehicle systems.
Likely Case
Unauthorized access to multiple users' vehicle data including location history, fuel statistics, and model information, leading to privacy violations and potential targeted attacks.
If Mitigated
Limited impact with proper authorization controls, restricting users to only their own vehicle data as intended.
🎯 Exploit Status
Exploitation requires authenticated access but minimal technical skill; detailed write-up available in Medium article demonstrating impact on 100,000 vehicles
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in references
Vendor Advisory: https://advisories.ncsc.nl/2025/ncsc-2025-0350.html
Restart Required: No
Instructions:
1. Review NCSC advisory for vendor-specific patch details 2. Apply server-side authorization fix as described 3. Validate that vehicleId parameter checks user permissions before returning data
🔧 Temporary Workarounds
Implement server-side authorization middleware
allAdd authorization layer that validates user has permission to access requested vehicleId before processing
Use indirect reference maps
allReplace direct object references with indirect, unpredictable identifiers that are mapped server-side
🧯 If You Can't Patch
- Implement WAF rules to detect and block suspicious vehicleId parameter patterns
- Enable detailed logging of all vehicleId access attempts and monitor for unauthorized patterns
🔍 How to Verify
Check if Vulnerable:
Test with authenticated user account by modifying vehicleId parameter in API requests to access other users' vehicle dataCheck Version:
Check application version through admin interface or vendor documentationVerify Fix Applied:
Attempt same IDOR test after patch; should receive authorization error or only own vehicle data📡 Detection & Monitoring
Log Indicators:
- Multiple vehicleId access attempts from single user account
- VehicleId parameter values outside user's authorized range
- Failed authorization checks for vehicleId
Network Indicators:
- API requests with sequential or predictable vehicleId patterns
- Unusual volume of vehicle data requests from single IP/user
SIEM Query:
source="vehicle_api" AND (vehicleId NOT IN authorized_vehicles OR vehicleId pattern matching /\d{5,}/)
