Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Restrict public access to Adobe Experience Manager instances (author/publish servers and management interfaces) using network controls (firewall rules, VPNs, and ACLs) so only trusted IPs and internal users can reach them.
- Compensating control
Deploy or tune a Web Application Firewall (WAF) or proxy to detect and block DOM-based XSS payloads and suspicious script injections targeting AEM endpoints, and create rules to block known malicious request patterns.
- Operational
Inform and train users and administrators that exploitation requires visiting a crafted webpage; advise avoiding clicking unknown links and opening untrusted pages while authenticated to AEM.
- Operational
Monitor application and web server logs for indications of DOM-based XSS attempts or anomalous script-injection requests, investigate any suspicious activity, and remediate affected sessions or accounts.
