Check if Vulnerable:

Check AEM version via /system/console/status-productinfo endpoint or CRX Package Manager

Check Version:

curl -u admin:password http://aem-host:port/system/console/status-productinfo | grep 'Adobe Experience Manager'

Verify Fix Applied:

Verify version is 6.5.23 or later and test form fields with XSS payloads

📡 Detection & Monitoring

Log Indicators:

  • Unusual content modifications by low-privileged users
  • JavaScript payloads in request logs
