Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Require authentication for submitting data to forms or disable anonymous form submission and any unnecessary form fields that accept user-supplied content to prevent low-privileged users from injecting scripts into stored fields.
Adobe Experience Manager form submission / anonymous input handling = require-authentication or disable - Compensating control
Deploy and tune a Web Application Firewall (WAF) or input-filtering layer to detect and block XSS payloads, and restrict access to AEM authoring/management interfaces to trusted IPs or VPNs until a vendor fix is available.
- Operational
Audit existing AEM content and form-submitted data for embedded scripts or suspicious HTML, remove or sanitize any discovered stored XSS payloads, and monitor logs for indicators of exploitation (suspicious form submissions or script injections).
