CVE-2023-3272
📋 TL;DR
This vulnerability in SICK ICR890-4 industrial cameras allows attackers to intercept unencrypted network traffic containing sensitive information. Any organization using these devices with default configurations is affected, particularly those in industrial environments where the cameras transmit data over networks.
💻 Affected Systems
- SICK ICR890-4 industrial camera
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers intercept authentication credentials, configuration data, or sensitive operational information, leading to unauthorized access, industrial espionage, or disruption of industrial processes.
Likely Case
Attackers on the same network segment capture unencrypted data, potentially exposing device credentials, configuration details, or operational data that could be used for further attacks.
If Mitigated
With proper network segmentation and encryption controls, attackers cannot access the traffic, limiting exposure to authorized personnel only.
🎯 Exploit Status
Exploitation requires network access to intercept traffic but no authentication to the device itself.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check SICK PSIRT for specific firmware versions
Vendor Advisory: https://sick.com/psirt
Restart Required: Yes
Instructions:
1. Download latest firmware from SICK support portal. 2. Backup current configuration. 3. Apply firmware update via web interface or maintenance tool. 4. Verify encryption is enabled in network settings.
🔧 Temporary Workarounds
Network Segmentation
allIsolate ICR890-4 cameras on separate VLAN with strict access controls
VPN Tunnel
allRoute all camera traffic through encrypted VPN tunnels
🧯 If You Can't Patch
- Implement strict network segmentation to isolate cameras from untrusted networks
- Deploy network encryption solutions like IPsec or TLS proxies for all camera communications
🔍 How to Verify
Check if Vulnerable:
Use network sniffing tools (Wireshark) on same network segment to check if camera traffic is unencryptedCheck Version:
Check firmware version in device web interface or via SICK maintenance softwareVerify Fix Applied:
After patching, verify network traffic shows encrypted protocols (TLS/HTTPS) instead of cleartext📡 Detection & Monitoring
Log Indicators:
- Unusual network connections to camera ports
- Multiple failed authentication attempts
Network Indicators:
- Unencrypted traffic on camera ports (typically 80/443)
- ARP spoofing or MITM activity near camera network
SIEM Query:
source_ip IN (camera_ips) AND protocol = 'HTTP' AND NOT is_encrypted = true
