CVE-2020-7879
📋 TL;DR
CVE-2020-7879 is an OS command injection vulnerability in ipTIME C200 IP cameras when synchronized with ipTIME NAS devices. Attackers can execute arbitrary commands on the camera by manipulating cookie values sent from the NAS without authentication. This affects organizations using vulnerable ipTIME camera/NAS combinations.
💻 Affected Systems
- ipTIME C200 IP Camera
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the IP camera allowing persistent access, lateral movement to other network devices, and use as a foothold for further attacks.
Likely Case
Remote code execution leading to camera compromise, surveillance disruption, and potential credential harvesting.
If Mitigated
Limited impact if cameras are isolated on separate VLANs with strict network segmentation.
🎯 Exploit Status
Exploitation requires network access to the camera and knowledge of the synchronization mechanism.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor for latest firmware
Vendor Advisory: https://www.boho.or.kr/krcert/secNoticeView.do?bulletin_writing_sequence=36365
Restart Required: Yes
Instructions:
1. Download latest firmware from ipTIME website. 2. Access camera web interface. 3. Navigate to firmware update section. 4. Upload and apply new firmware. 5. Reboot camera.
🔧 Temporary Workarounds
Disable NAS synchronization
allPrevent the vulnerable synchronization feature from being used
Access camera web interface -> Settings -> NAS Sync -> Disable
Network segmentation
allIsolate cameras on separate VLAN from critical systems
🧯 If You Can't Patch
- Disable remote access to cameras and restrict to internal network only
- Implement strict firewall rules blocking unnecessary ports and protocols
🔍 How to Verify
Check if Vulnerable:
Check if camera is synchronized with ipTIME NAS and examine firmware version against known vulnerable versionsCheck Version:
Check camera web interface -> System Information -> Firmware VersionVerify Fix Applied:
Verify firmware version has been updated and test synchronization feature for command injection📡 Detection & Monitoring
Log Indicators:
- Unusual wget commands in system logs
- Unexpected cookie values in HTTP requests
- Abnormal process execution
Network Indicators:
- Suspicious HTTP requests to camera with manipulated cookie headers
- Unexpected outbound connections from camera
