CVE-2016-6545
📋 TL;DR
This vulnerability in iTrack Easy allows attackers to intercept and replay user credentials since passwords are transmitted with every request instead of using secure session cookies. Affected users are anyone using iTrack Easy tracking devices with vulnerable firmware. The design flaw makes session termination impossible without password changes.
💻 Affected Systems
- iTrack Easy tracking devices
📦 What is this software?
Itrackeasy by Ieasytec
⚠️ Risk & Real-World Impact
Worst Case
Complete account takeover and tracking data exposure, allowing attackers to monitor user locations, steal personal data, and potentially compromise associated accounts.
Likely Case
Credential theft leading to unauthorized access to tracking data and location information, enabling stalking or theft of tracked assets.
If Mitigated
Limited impact if strong network segmentation and monitoring are in place, though credential exposure risk remains.
🎯 Exploit Status
Exploitation requires intercepting BLE communications or network traffic to capture credentials. Public research and tools exist for BLE traffic analysis.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Firmware updates from vendor (specific version unknown)
Vendor Advisory: https://www.kb.cert.org/vuls/id/974055
Restart Required: Yes
Instructions:
1. Contact iTrack vendor for firmware updates. 2. Apply firmware updates to all affected devices. 3. Force password changes for all users after update. 4. Verify implementation uses proper session management.
🔧 Temporary Workarounds
Network segmentation and monitoring
allIsolate tracking devices on separate network segments and monitor for unusual BLE traffic patterns.
Frequent password rotation
allImplement mandatory frequent password changes to limit credential exposure window.
🧯 If You Can't Patch
- Discontinue use of affected iTrack Easy devices for sensitive tracking purposes
- Implement network-level encryption and strict access controls for device communications
🔍 How to Verify
Check if Vulnerable:
Monitor network traffic or BLE communications for base64-encoded passwd parameters in POST requests. Check if session cookies are properly implemented.Check Version:
Check device firmware version through manufacturer's app or management interface (vendor-specific command).Verify Fix Applied:
Verify firmware version is updated and test that passwords are no longer transmitted with each request. Confirm proper session cookie usage.📡 Detection & Monitoring
Log Indicators:
- Repeated authentication failures
- Unusual location data access patterns
- Multiple sessions from same credentials
Network Indicators:
- Base64 encoded passwd fields in POST requests over BLE/HTTPS
- Lack of session cookie usage in authentication flows
SIEM Query:
search source="network_traffic" (http_method=POST AND http_uri CONTAINS "auth" AND http_body CONTAINS "passwd=") OR (protocol="ble" AND data CONTAINS "passwd")🔗 References
