AI-suggested
1. Immediately review and restrict user privileges to ensure that only necessary personnel have high-level authenticated access to Liferay portals. 2. Implement strict input validation and output encoding on the affected parameters at the web application firewall (WAF) or reverse proxy level to block malicious scripts before they reach the application. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts within the portal environment. 4. Monitor logs for unusual activity related to the vulnerable parameters, including repeated or anomalous requests that may indicate exploitation attempts. 5. Educate users with high privileges about the risks of phishing and social engineering attacks that could trigger reflected XSS payloads. 6. Stay updated with Liferay vendor advisories and apply patches or updates as soon as they become available. 7. Consider deploying runtime application self-protection (RASP) solutions that can detect and block XSS attacks in real time. 8. Conduct regular security assessments and penetration testing focused on web application vulnerabilities, including reflected XSS scenarios.
