Adobe Experience Manager Misconfiguration
Description
Adobe Experience Manager (AEM) is an enterprise content management platform used for building websites, mobile applications, and forms.
This vulnerability identifies a misconfiguration in your AEM installation that exposes administrative interfaces, sensitive endpoints, or debugging features to unauthenticated users. Common misconfigurations include exposed servlets, unrestricted access to the CRX/DE development environment, accessible user enumeration endpoints, or improperly secured dispatcher configurations.
These misconfigurations allow remote attackers to access sensitive system information, enumerate users, or interact with administrative functions without authentication.
Remediation
1. Apply the latest Adobe Experience Manager security hotfixes and patches as documented in Adobe Security Bulletin APSB16-05 and subsequent security advisories for your AEM version.
2. Review and restrict access to sensitive AEM endpoints by configuring your dispatcher or web server to block unauthenticated access to:
- /crx/de (CRX/DE Lite development interface)
- /system/console (Felix/OSGi console)
- /crx/explorer (CRX Explorer)
- /.json and .infinity.json selectors on sensitive paths
- /etc/replication.html and other administrative servlets
3. Implement proper authentication and authorization controls for all administrative interfaces. Ensure default credentials are changed immediately and enforce strong password policies requiring complex, unique passwords of at least 12 characters.
4. Configure the AEM Dispatcher with appropriate filters to deny access to sensitive paths and file extensions. Review the dispatcher.any configuration file to ensure proper security rules are in place.
5. Disable or remove any unnecessary servlets, especially in production environments. Review OSGi configurations to deactivate debugging and development features.
6. Conduct a comprehensive security audit of your AEM instance using Adobe's security checklist and consider implementing IP-based access restrictions for administrative interfaces.
