CVE-2025-68930
📋 TL;DR
This CVE describes a Cross-Site WebSocket Hijacking vulnerability in Traccar GPS tracking system versions up to 6.11.1. Attackers can bypass Same Origin Policy to establish WebSocket connections using stolen user credentials, potentially intercepting real-time GPS data or sending malicious commands. All users running vulnerable Traccar versions are affected.
💻 Affected Systems
- Traccar GPS Tracking System
📦 What is this software?
Traccar by Traccar
⚠️ Risk & Real-World Impact
Worst Case
Attackers intercept real-time GPS tracking data, manipulate device commands, track user locations, and potentially compromise the entire tracking infrastructure.
Likely Case
Attackers hijack WebSocket sessions to monitor GPS data streams, inject false location data, or disrupt tracking operations.
If Mitigated
With proper origin validation, only legitimate same-origin requests can establish WebSocket connections, preventing cross-site hijacking.
🎯 Exploit Status
Exploitation requires tricking authenticated users into visiting malicious sites that initiate WebSocket connections.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://github.com/traccar/traccar/security/advisories/GHSA-69x6-wcx2-vghp
Restart Required: Yes
Instructions:
Monitor the Traccar GitHub repository for security updates. When available, update to the patched version and restart the Traccar service.
🔧 Temporary Workarounds
Origin Header Validation
allImplement server-side validation of Origin headers during WebSocket handshake
Modify WebSocket endpoint code to validate Origin header matches expected domains
WebSocket CSRF Tokens
allAdd CSRF tokens to WebSocket connection requests
Implement token validation for WebSocket upgrade requests
🧯 If You Can't Patch
- Implement a reverse proxy with strict Origin header validation
- Restrict WebSocket endpoint access to trusted IP addresses only
🔍 How to Verify
Check if Vulnerable:
Check if Traccar version is 6.11.1 or earlier and WebSocket endpoint accepts connections without Origin validationCheck Version:
Check Traccar web interface or server logs for version informationVerify Fix Applied:
Test WebSocket connections with different Origin headers - only same-origin requests should succeed📡 Detection & Monitoring
Log Indicators:
- WebSocket connections from unexpected origins
- Multiple failed WebSocket handshake attempts
Network Indicators:
- WebSocket traffic from non-legitimate domains
- Suspicious WebSocket upgrade requests
SIEM Query:
websocket AND (origin NOT IN allowed_domains) OR (websocket AND status_code=101 AND suspicious_user_agent)
