CVE-2019-11014
📋 TL;DR
This vulnerability allows attackers to spoof VStarCam camera servers on local networks, intercept client connections, and steal camera login credentials. It affects users of the Eye4 application on Android, iOS, and Windows that communicate with vulnerable VStarCam devices. Attackers can perform man-in-the-middle attacks to capture credentials and potentially take control of cameras.
💻 Affected Systems
- VStarCam cameras using vstc.vscam.client library
- Eye4 application for Android
- Eye4 application for iOS
- Eye4 application for Windows
📦 What is this software?

⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full control of security cameras, access live feeds, manipulate recordings, disable security monitoring, and potentially pivot to other network devices using stolen credentials.
Likely Case
Attackers intercept camera credentials, access live video feeds, and potentially disable legitimate camera connections, compromising privacy and security monitoring.
If Mitigated
With network segmentation and proper authentication, impact is limited to isolated camera networks with no access to sensitive systems.
🎯 Exploit Status
Exploitation requires local network access; attack tools can be built using published technical details from security researchers.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown specific version - check vendor updates
Vendor Advisory: No official vendor advisory URL found in references
Restart Required: Yes
Instructions:
1. Update Eye4 application to latest version from official app stores. 2. Update camera firmware if available from manufacturer. 3. Restart both application and camera after updates.
🔧 Temporary Workarounds
Network Segmentation
allIsolate camera network from other devices to limit attack surface
Disable Broadcast Discovery
allConfigure cameras with static IPs and disable automatic discovery features
🧯 If You Can't Patch
- Segment camera network using VLANs or separate physical network
- Implement network monitoring for unusual broadcast traffic or spoofing attempts
🔍 How to Verify
Check if Vulnerable:
Check if using VStarCam cameras with Eye4 application; test if camera responds to broadcast discovery requests with unencrypted credentials.Check Version:
Check app version in application settings; camera firmware typically checked via manufacturer's management interface.Verify Fix Applied:
Verify application and firmware versions are updated; test that camera discovery no longer broadcasts sensitive information in clear text.📡 Detection & Monitoring
Log Indicators:
- Multiple camera discovery responses from same IP
- Failed authentication attempts from unexpected IPs
- Camera connection drops followed by new connections
Network Indicators:
- Excessive UDP broadcast traffic on port 8600 (typical discovery port)
- Multiple devices responding to single discovery request
- Unencrypted credential transmission in network captures
SIEM Query:
source_ip=* AND (udp.port=8600 OR protocol="VStarCam") AND event_count>10 WITHIN 5min
