CVE-2026-22644
📋 TL;DR
This vulnerability allows attackers to steal authentication tokens when they are passed in URL query parameters, potentially enabling session hijacking and unauthorized access. It affects systems that handle authentication tokens insecurely via URLs, particularly those exposed to logging mechanisms like server logs, proxy logs, or Referer headers.
💻 Affected Systems
- SICK products with vulnerable authentication implementations
📦 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
Attackers gain full unauthorized access to user accounts, potentially compromising sensitive data, performing malicious actions, or escalating privileges within affected systems.
Likely Case
Session hijacking leading to unauthorized access to user accounts, with potential data exposure or manipulation depending on application functionality.
If Mitigated
Limited impact with proper token handling and logging controls, potentially only exposing non-sensitive information or requiring additional exploitation steps.
🎯 Exploit Status
Exploitation requires access to logs containing URL parameters or ability to capture Referer headers through user interaction with malicious links.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Consult SICK advisory for specific patched versions
Vendor Advisory: https://sick.com/psirt
Restart Required: Yes
Instructions:
1. Review SICK advisory at provided URL. 2. Identify affected products and versions. 3. Apply vendor-provided patches or updates. 4. Restart affected services after patching. 5. Verify authentication tokens are no longer passed in URLs.
🔧 Temporary Workarounds
Disable URL parameter logging
allConfigure web servers and proxies to exclude query parameters from logs to prevent token exposure.
# Apache: Set LogFormat to exclude query string
# Nginx: Use $request_uri without $query_string in log_format
Implement secure token handling
allMove authentication tokens from URL parameters to secure HTTP headers or secure cookies.
# Application code modification required
# Use Authorization headers or HttpOnly, Secure cookies
🧯 If You Can't Patch
- Implement network segmentation to restrict access to systems handling sensitive authentication
- Deploy web application firewall rules to block requests with authentication tokens in URLs
🔍 How to Verify
Check if Vulnerable:
Inspect application traffic to see if authentication tokens appear in URL query parameters during requests.Check Version:
Consult product documentation for version checking; typically via web interface or administrative commands specific to SICK products.Verify Fix Applied:
Confirm authentication tokens are no longer visible in URL parameters and are instead in secure headers or cookies.📡 Detection & Monitoring
Log Indicators:
- URLs containing authentication tokens in query parameters in server/proxy logs
- Referer headers containing authentication tokens
Network Indicators:
- HTTP requests with authentication tokens visible in URL query strings
SIEM Query:
source="web_logs" AND url="*token=*" OR url="*auth=*" OR url="*session=*"🔗 References
