Adobe Experience Manager server-side input validation and output encoding for form fields = enabled - Compensating control
Deploy a Web Application Firewall (WAF) or request-filtering layer to block common XSS payloads and script tags in form submissions, and apply content filtering rules for POST data to vulnerable endpoints.
- Compensating control
Restrict access to pages and endpoints that accept user-submitted content: require authentication/authorization for submission, restrict submission endpoints to trusted IP ranges where feasible, and limit low-privileged users' ability to create content.
- Operational
Scan existing stored content (form submissions, database entries, attachments) for malicious script payloads, remove or neutralize any found, and remediate affected pages to remove stored XSS content.
- Operational
Monitor Adobe security advisories for this issue and apply vendor-provided fixes or patches as soon as they are made available; plan for timely patching once a fixed release is published.
