MA-1377.082025: MyCERT Advisory - Critical Zero - Day Vulnerabilities in Adobe Experience Manager (AEM)


1.0 Introduction
Recently, Adobe released and emergency security updates to address two critical zero-day vulnerabilities in AEM Forms on JEE tracked as CVE-2025-54253: Arbitrary Code Execution and CVE-2025-54254: XML External Entity (XXE) Injection.

2.0 Impact
These vulnerabilities allow attackers to bypass security mechanisms and execute arbitrary code on affected systems. Exploitation does not require user interaction, and the scope of impact is elevated, making it especially dangerous for internet-facing or internal AEM instances. Furthermore, attackers can exploit this flaw to read arbitrary files from the local file systems, potentially exposing sensitive data such as credentials, configuration files, or internal documentation.

  • Adobe AEM Forms on JEE versions 6.5.23.0 and earlier.
