AI-suggested
- Apply official patches or updates from Liferay as soon as they become available to address the vulnerability directly.
- In the absence of patches, implement strict input validation and output encoding on the _com_liferay_portal_language_override_web_internal_portlet_PLOPortlet_selectedLanguageId parameter to neutralize malicious scripts.
- Deploy or tune Web Application Firewalls (WAFs) to detect and block suspicious requests containing script injection attempts targeting this parameter.
- Conduct user awareness training to educate users about the risks of clicking unknown or suspicious links, especially those purporting to change language settings or similar features.
- Review and restrict the exposure of Liferay portals to only necessary user groups and networks, employing network segmentation and access controls.
- Monitor web server and application logs for unusual request patterns or error messages related to the vulnerable parameter.
- Consider implementing Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers.
- Regularly audit and test web applications for XSS vulnerabilities using automated scanners and manual penetration testing.
