Vendor Advisory: https://docs.payara.fish/community/docs/Release%20Notes/Release%20Notes%206.2024.10.html
Restart Required: Yes
Instructions:
1. Download the patched version from Payara's official website. 2. Backup current configuration and deployments. 3. Stop the Payara Server. 4. Install the patched version. 5. Restore configurations and deployments. 6. Restart the server.
🔧 Temporary Workarounds
Disable Admin Console
allTemporarily disable the Admin Console to prevent exploitation until patching is possible.
asadmin set configs.config.server-config.admin-service.property.adminConsoleEnabled=false
Restrict Admin Console Access
allLimit access to the Admin Console using network controls or authentication mechanisms.
Configure firewall rules to restrict access to Admin Console port (typically 4848)
🧯 If You Can't Patch
- Implement strict input validation and output encoding for all Admin Console inputs.
- Use a web application firewall (WAF) with XSS protection rules enabled.
