CVE-2018-12670
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary operating system commands on SV3C L-SERIES HD CAMERA devices through command injection. Attackers can gain full control of affected cameras, potentially compromising the entire device. Organizations using these specific camera models and firmware versions are affected.
💻 Affected Systems
- SV3C L-SERIES HD CAMERA
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device takeover leading to persistent backdoor installation, lateral movement to other network devices, data exfiltration, and use in botnets or as pivot points for further attacks.
Likely Case
Camera compromise allowing video stream interception, device manipulation (disabling/redirecting feeds), credential theft, and use as foothold for network reconnaissance.
If Mitigated
Limited impact if cameras are isolated in separate VLANs with strict network segmentation and no internet exposure.
🎯 Exploit Status
Exploitation details published in Bishop Fox research. Attack requires network access to camera web interface.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Contact SV3C for updated firmware. Consider replacing affected devices with patched alternatives.
🔧 Temporary Workarounds
Network Segmentation
allIsolate cameras in separate VLAN with strict firewall rules blocking all inbound traffic except from authorized management systems.
Access Control Lists
allImplement IP-based restrictions to allow only authorized management IPs to access camera web interface.
🧯 If You Can't Patch
- Remove internet exposure: Ensure cameras are not directly accessible from the internet
- Implement strict network segmentation and monitor for unusual outbound connections
🔍 How to Verify
Check if Vulnerable:
Check firmware version via camera web interface: Settings > System > Version Information. Look for affected version strings.Check Version:
curl -s http://[CAMERA_IP]/cgi-bin/version.cgi (if available) or check web interfaceVerify Fix Applied:
Verify firmware has been updated to a version not listed in affected versions. No known patched version exists.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in system logs
- Multiple failed login attempts followed by successful access
- Changes to system configuration files
Network Indicators:
- Unusual outbound connections from camera
- Traffic to known malicious IPs
- Unexpected port scans originating from camera
