Aug 05, 2025
Applies to: AEM 6.5 Forms Service Pack 23
Setup instructions: Mitigating XXE, Configuration, and Remote Code Execution (CVE-2025-49533) Vulnerabilities for AEM Forms on JEE

  • Enhanced security by addressing a Remote Code Execution (RCE) vulnerability in Adobe Experience Manager (AEM) Forms. The issue was related to Struts development mode in the admin user interface (UI), which allowed arbitrary Object-Graph Navigation Language (OGNL) evaluation through debug functionality. This fix ensures that Struts development mode is disabled and appropriate security filters are applied to prevent unauthorized access.

  • Improved protection against Extensible Markup Language (XML) External Entity (XXE) vulnerabilities in the Electronic Document Component (EDC) module of Adobe Experience Manager (AEM) Forms. The vulnerabilities were due to improper handling of XML documents without XXE protections, which could lead to local file reads. The fix includes:

    • Ensuring that the DocumentBuilderFactory used in the SecurityCheckHandler class is configured to prevent XXE attacks.
    • Updating the EDC web service to handle XML documents securely, preventing unauthorized access to local files.
