CVE-2025-0592
📋 TL;DR
This vulnerability allows remote attackers with low privileges to execute arbitrary shell commands by uploading a manipulated firmware file to affected SICK devices. It affects industrial control systems and IoT devices running vulnerable firmware versions. Attackers could gain full control of compromised devices.
💻 Affected Systems
- SICK industrial devices with vulnerable firmware
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete device takeover leading to industrial process disruption, data theft, or lateral movement into operational technology networks.
Likely Case
Unauthorized command execution allowing data exfiltration, device manipulation, or persistence establishment.
If Mitigated
Limited impact with proper network segmentation and firmware validation controls in place.
🎯 Exploit Status
Requires attacker to have low-privileged access and ability to upload firmware files. No public exploit code available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check SICK advisory for specific patched versions
Vendor Advisory: https://sick.com/psirt
Restart Required: No
Instructions:
1. Download latest firmware from SICK support portal. 2. Backup current configuration. 3. Upload new firmware via device management interface. 4. Verify successful update.
🔧 Temporary Workarounds
Disable firmware upload functionality
allRemove or restrict firmware upload capabilities for low-privileged users
Device-specific configuration commands; consult SICK documentation
Implement firmware validation
allAdd digital signature verification for all firmware uploads
Configure device to only accept signed firmware updates
🧯 If You Can't Patch
- Network segmentation: Isolate affected devices in separate VLAN with strict access controls
- Implement application allowlisting to prevent unauthorized command execution
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against SICK advisory. Review if low-privileged users can upload firmware.Check Version:
Device-specific command; typically via web interface or CLI 'show version' equivalentVerify Fix Applied:
Verify firmware version matches patched version from SICK advisory. Test firmware upload with low-privileged account.📡 Detection & Monitoring
Log Indicators:
- Unexpected firmware upload events
- Shell command execution from firmware process
- Authentication from unusual accounts for firmware operations
Network Indicators:
- Firmware upload traffic to unexpected destinations
- Outbound connections from devices post-firmware update
SIEM Query:
