CVE-2013-2568
📋 TL;DR
This is a critical command injection vulnerability in Zavio IP Cameras that allows remote attackers to execute arbitrary commands on affected devices. Attackers can exploit this by sending specially crafted requests to the wireless configuration CGI script, potentially gaining full control of the camera. All Zavio IP Camera users running firmware version 1.6.3 or earlier are affected.
💻 Affected Systems
- Zavio IP Cameras
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the IP camera allowing attackers to execute arbitrary commands, pivot to internal networks, install persistent backdoors, or use the device as part of a botnet.
Likely Case
Remote code execution leading to camera compromise, video stream interception, device repurposing for malicious activities, or denial of service.
If Mitigated
Limited impact if cameras are isolated in separate network segments with strict firewall rules preventing external access to management interfaces.
🎯 Exploit Status
Exploitation requires no authentication and has been publicly documented with proof-of-concept code available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Firmware versions after 1.6.3
Vendor Advisory: https://www.coresecurity.com/advisories/zavio-ip-cameras-multiple-vulnerabilities
Restart Required: Yes
Instructions:
1. Download latest firmware from Zavio support site. 2. Log into camera web interface. 3. Navigate to System > Maintenance > Firmware Upgrade. 4. Upload firmware file. 5. Wait for automatic reboot.
🔧 Temporary Workarounds
Network Segmentation
allIsolate IP cameras in separate VLAN with strict firewall rules blocking external access to management interfaces.
Access Control
allImplement strict network access controls to prevent unauthorized access to camera management interfaces.
🧯 If You Can't Patch
- Segment cameras on isolated network with no internet access
- Implement strict firewall rules blocking all access to /cgi-bin/mft/wireless_mft.cgi
🔍 How to Verify
Check if Vulnerable:
Check firmware version in camera web interface under System > Information. If version is 1.6.3 or earlier, device is vulnerable.Check Version:
curl -s http://[CAMERA_IP]/cgi-bin/hi3510/param.cgi?cmd=getserverinfo | grep FirmwareVerify Fix Applied:
After firmware update, verify version shows higher than 1.6.3 and attempt to access /cgi-bin/mft/wireless_mft.cgi with test payloads to confirm patched.📡 Detection & Monitoring
Log Indicators:
- Unusual CGI script access patterns
- Multiple failed authentication attempts to camera interface
- Suspicious commands in web server logs
Network Indicators:
- HTTP requests to /cgi-bin/mft/wireless_mft.cgi with shell metacharacters
- Outbound connections from cameras to unusual destinations
- Sudden traffic spikes from camera devices
SIEM Query:
source="camera_logs" AND (uri="/cgi-bin/mft/wireless_mft.cgi" AND (query="*;*" OR query="*|*" OR query="*`*"))🔗 References
