Check application version in admin interface or via vendor documentation.Verify Fix Applied:
After patching, attempt the same test - JavaScript should be displayed as plain text without execution.📡 Detection & Monitoring
Log Indicators:
- Unusual comment entries containing script tags or JavaScript code
- Multiple failed login attempts followed by comment creation
Network Indicators:
- HTTP requests with JavaScript payloads in comment parameters
- Unexpected outbound connections from user browsers after viewing logs
SIEM Query:
source="web_logs" AND (uri="*/comment*" OR uri="*/history*") AND (message="*<script>*" OR message="*javascript:*")
