CVE-2026-22912
📋 TL;DR
This vulnerability allows attackers to redirect authenticated users to malicious websites through improper validation of a login parameter. It affects systems using SICK products with vulnerable authentication implementations. The primary risk is credential theft through phishing-style attacks.
💻 Affected Systems
- SICK industrial automation and sensor products with web interfaces
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers steal user credentials via malicious redirects, leading to account compromise and potential lateral movement within affected systems.
Likely Case
Users are redirected to phishing sites that capture login credentials or install malware.
If Mitigated
Proper input validation and URL filtering prevent redirects to untrusted domains, limiting impact to failed attempts.
🎯 Exploit Status
Exploitation requires user interaction (authentication) and knowledge of vulnerable parameter; no public exploits known
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific fixed versions
Vendor Advisory: https://sick.com/psirt
Restart Required: Yes
Instructions:
1. Review SICK PSIRT advisory. 2. Identify affected products. 3. Apply vendor-provided patches or firmware updates. 4. Restart affected devices.
🔧 Temporary Workarounds
Implement URL validation
allAdd server-side validation to reject redirect URLs to untrusted domains
Use Content Security Policy
allImplement CSP headers to restrict redirect destinations
🧯 If You Can't Patch
- Isolate affected systems from internet access
- Implement network monitoring for suspicious redirect patterns
🔍 How to Verify
Check if Vulnerable:
Test authentication flows with malicious redirect parameters; check if redirects to external domains are allowedCheck Version:
Check device firmware version via web interface or vendor toolsVerify Fix Applied:
Verify patches prevent redirects to untrusted domains; test with same malicious parameters📡 Detection & Monitoring
Log Indicators:
- Unusual redirect patterns in authentication logs
- Requests with external URLs in redirect parameters
Network Indicators:
- HTTP 302/303 redirects to unfamiliar domains post-authentication
SIEM Query:
source="web_logs" AND (status=302 OR status=303) AND url CONTAINS "redirect=" AND NOT url CONTAINS "trusted-domain.com"🔗 References
