CVE-2026-22916
📋 TL;DR
This vulnerability allows low-privileged attackers to trigger critical system functions like reboot or factory reset without proper authorization. It affects systems running vulnerable versions of SICK products where privilege escalation controls are insufficient. This could lead to service disruption or configuration loss.
💻 Affected Systems
- SICK industrial automation and sensor products
📦 What is this software?
⚠️ 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 system disruption through unauthorized factory reset, requiring full reconfiguration and extended downtime.
Likely Case
Service disruption through unauthorized reboots affecting operational continuity.
If Mitigated
Minimal impact with proper access controls and monitoring in place.
🎯 Exploit Status
Exploitation requires some level of system access but minimal technical skill once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Consult vendor advisory for specific patched versions
Vendor Advisory: https://sick.com/psirt
Restart Required: Yes
Instructions:
1. Check vendor advisory for affected products. 2. Download and apply recommended firmware updates. 3. Restart affected devices. 4. Verify proper privilege controls are in place.
🔧 Temporary Workarounds
Implement strict access controls
allRestrict user privileges to prevent low-privileged users from accessing critical functions
Network segmentation
allIsolate affected systems from general network access
🧯 If You Can't Patch
- Implement strict role-based access control (RBAC) to limit who can access critical functions
- Monitor system logs for unauthorized reboot or reset attempts and implement alerting
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against vendor advisory and test if low-privileged users can trigger reboot/reset functionsCheck Version:
Device-specific; consult product documentation for version check commandsVerify Fix Applied:
Verify firmware version is updated and test that low-privileged users cannot trigger critical functions📡 Detection & Monitoring
Log Indicators:
- Unauthorized reboot commands
- Factory reset attempts from non-admin accounts
- Privilege escalation attempts
Network Indicators:
- Unexpected device restarts
- Configuration changes from unauthorized sources
