CVE-2025-27448
📋 TL;DR
This cross-site scripting (XSS) vulnerability allows attackers to inject malicious JavaScript into dashboard names in a web application. When users view these dashboards, the injected code executes in their browsers, potentially stealing session cookies or performing actions on their behalf. Any organization using the vulnerable web application with dashboard creation functionality is affected.
💻 Affected Systems
- Unknown web application from SICK or Endress+Hauser based on references
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attacker steals administrator session cookies, gains full administrative access to the web application, and potentially compromises the entire system or network.
Likely Case
Attacker steals user session cookies, performs unauthorized actions as authenticated users, or redirects users to malicious sites.
If Mitigated
With proper input validation and output encoding, the attack fails to execute, resulting in no impact beyond failed exploitation attempts.
🎯 Exploit Status
Requires ability to create dashboards (some level of authentication). XSS exploitation is well-understood with many available frameworks.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://sick.com/psirt
Restart Required: No
Instructions:
1. Check vendor advisory at sick.com/psirt
2. Apply recommended patch or update
3. Verify fix by testing dashboard name input validation
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to reject or sanitize JavaScript in dashboard names
Implementation specific to application framework
Output Encoding
allEncode dashboard names before rendering in HTML to prevent script execution
Use framework-specific encoding functions (e.g., HTML entities)
🧯 If You Can't Patch
- Disable dashboard creation functionality for non-administrative users
- Implement web application firewall (WAF) rules to block XSS payloads in dashboard names
🔍 How to Verify
Check if Vulnerable:
Test by creating a dashboard with name containing <script>alert('XSS')</script> and check if alert executesCheck Version:
Check application version via admin interface or configuration filesVerify Fix Applied:
Repeat vulnerability test - script should not execute and should be displayed as plain text📡 Detection & Monitoring
Log Indicators:
- Unusual dashboard creation events
- Dashboard names containing script tags or JavaScript patterns
Network Indicators:
- HTTP requests with JavaScript in dashboard name parameters
SIEM Query:
