🔍 How to Verify
Check if Vulnerable:
Test by accessing /dpw/scripts/cgiip.exe/WService?tabfields=<script>alert('XSS')</script> and checking if script executes in browser.Check Version:
Check application version in admin interface or configuration files.Verify Fix Applied:
After patching, repeat the test; the script should not execute and input should be sanitized.📡 Detection & Monitoring
Log Indicators:
- HTTP requests to /dpw/scripts/cgiip.exe/WService with tabfields parameter containing script tags or JavaScript keywords.
Network Indicators:
- Unusual outbound traffic from application server to external domains following suspicious requests.
SIEM Query:
source="web_server" AND uri="/dpw/scripts/cgiip.exe/WService" AND query CONTAINS "tabfields" AND (query CONTAINS "<script>" OR query CONTAINS "javascript:")
