CVE-2026-22920
📋 TL;DR
This vulnerability affects devices where passwords are stored without proper salting, allowing attackers to more easily extract and crack passwords through offline attacks. It impacts systems using vulnerable password storage mechanisms, particularly in industrial control systems and embedded devices. Organizations using affected SICK devices should assess their exposure.

- 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
Attackers gain administrative access to critical systems, potentially compromising industrial processes, stealing sensitive data, or disrupting operations.
Likely Case
Attackers with physical or network access extract password hashes and crack them offline, gaining unauthorized access to device management interfaces.
If Mitigated
With proper network segmentation and access controls, attackers cannot reach vulnerable systems to extract password data.
🎯 Exploit Status
Exploitation requires access to password storage (files/database) and ability to perform offline password cracking. No public exploits known at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown - check vendor advisory
Vendor Advisory: https://www.sick.com/.well-known/csaf/white/2026/sca-2026-0001.json
Restart Required: Yes
Instructions:
1. Check SICK advisory for affected products. 2. Download and apply vendor-provided firmware updates. 3. Restart devices after patching. 4. Change all passwords after update.
🔧 Temporary Workarounds
Enforce Strong Password Policy
allRequire complex, unique passwords to make cracking more difficult even without proper salting
Network Segmentation
allIsolate vulnerable devices from untrusted networks to prevent access to password storage
🧯 If You Can't Patch
- Implement strict network access controls to limit who can access affected devices
- Enable multi-factor authentication if supported, or implement compensating controls like jump hosts
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against vendor advisory. Examine password storage implementation if possible.Check Version:
Device-specific - consult vendor documentation for version checking commandsVerify Fix Applied:
Verify firmware version is updated to patched version. Test that new passwords are stored with proper salting.📡 Detection & Monitoring
Log Indicators:
- Unusual access to password files or databases
- Multiple failed authentication attempts
- Unauthorized configuration changes
Network Indicators:
- Unexpected connections to device management interfaces
- Traffic patterns suggesting password hash extraction
