✅ Official Fix
Patch Version: Not available
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a newer version of baseweb JSite if available, or implement workarounds.
🔧 Temporary Workarounds
Restrict Access to /druid/index.html
allBlock or restrict access to the vulnerable endpoint using web server configuration or network controls.
# Apache: <Location /druid/index.html> Require all denied </Location>
# Nginx: location /druid/index.html { deny all; }
Implement Authentication
allAdd authentication requirements to access the Druid monitoring console.
# Add basic auth to Apache: <Location /druid> AuthType Basic AuthName "Restricted" AuthUserFile /path/to/.htpasswd Require valid-user </Location>
🧯 If You Can't Patch
- Implement network segmentation to isolate the vulnerable system from critical assets
- Deploy a web application firewall (WAF) with rules to block unauthorized access to /druid/index.html
🔍 How to Verify
Check if Vulnerable:
Attempt to access http://[target]/druid/index.html without authentication. If accessible, the system is vulnerable.Check Version:
Check baseweb JSite configuration files or documentation for version information, typically in package.json or similar manifest files.Verify Fix Applied:
After implementing workarounds, verify that unauthorized access to /druid/index.html is blocked and proper authentication is required.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to /druid/index.html
- Successful access to /druid/index.html without authentication logs
Network Indicators:
- HTTP requests to /druid/index.html from unauthorized IPs
- Unusual traffic patterns to the Druid monitoring endpoint
SIEM Query:
source="web_server_logs" AND (uri="/druid/index.html" OR uri="/druid/") AND (response_code=200 OR auth_failure=false)
