CVE-2018-7233
📋 TL;DR
This vulnerability allows remote command execution on Schneider Electric Pelco Sarix Professional cameras by exploiting insufficient input validation of shell meta characters in 'model_name' or 'mac_address' parameters. Attackers can execute arbitrary commands with system privileges. All organizations using affected firmware versions are at risk.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands, install malware, pivot to internal networks, or render cameras inoperable.
Likely Case
Remote code execution leading to camera compromise, surveillance disruption, or credential theft from connected systems.
If Mitigated
Limited impact with proper network segmentation and access controls preventing external exploitation.
🎯 Exploit Status
Exploitation requires network access to camera interface but no authentication. Simple HTTP requests with crafted parameters can trigger the vulnerability.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 3.29.67 or later
Vendor Advisory: https://www.schneider-electric.com/en/download/document/SEVD-2018-058-01/
Restart Required: Yes
Instructions:
1. Download firmware version 3.29.67 or later from Schneider Electric portal. 2. Backup camera configuration. 3. Upload firmware via web interface. 4. Wait for automatic reboot. 5. Verify firmware version after update.
🔧 Temporary Workarounds
Network segmentation
allIsolate cameras on separate VLAN with strict firewall rules blocking external access
Access control restrictions
allImplement IP whitelisting and strong authentication for camera management interfaces
🧯 If You Can't Patch
- Implement strict network segmentation to isolate cameras from internet and critical internal networks
- Deploy intrusion detection systems to monitor for exploitation attempts and anomalous camera behavior
🔍 How to Verify
Check if Vulnerable:
Check firmware version via camera web interface: Settings > System > Firmware VersionCheck Version:
Check via HTTP request to camera interface or web interface navigationVerify Fix Applied:
Verify firmware version shows 3.29.67 or higher in web interface📡 Detection & Monitoring
Log Indicators:
- Unusual HTTP requests containing shell meta characters in parameters
- Multiple failed authentication attempts followed by successful access
- Unexpected system commands in camera logs
Network Indicators:
- HTTP requests with crafted model_name or mac_address parameters
- Unusual outbound connections from cameras
- Traffic to camera management ports from unexpected sources
SIEM Query:
source="camera_logs" AND ("model_name" OR "mac_address") AND ("$" OR "|" OR ";" OR "&" OR "`")
