Adobe Experience Manager versions 6.5.23 and earlier are affected by an Improper Restriction of XML External Entity Reference ('XXE') vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files on the local file system, scope is changed. Exploitation of this issue does not require user interaction.

  • Target the SOAP endpoint /edcws/services/urn:EDCLicenseService via HTTP POST; look for XML payloads containing an <EDCSecurity> element combined with an XXE ENTITY declaration (<!ENTITY ) — no authentication is required for exploitation.
  • The PCRE pattern in the Snort rule matches XXE entity declaration variants including percent-encoded parameter entities (%25 / &#x25;) and bare % — flag any of these patterns immediately following <!ENTITY in the POST body to the target endpoint.
  • Monitor for unauthenticated POST requests to AEM Forms on JEE SOAP services; successful exploitation results in local file disclosure (e.g., win.ini) — look for file content in HTTP responses.
  • Restrict or alert on inbound internet access to AEM Forms endpoints as a compensating control if patching is not immediately possible.
  • Public PoC exploit chain is available; treat any exploitation attempt as high-confidence given the low complexity and no-auth-required nature of the attack.
  • ·The Snort rule (sid:2064046) requires TLS decryption to be effective against HTTPS-protected AEM Forms deployments, as indicated by the tls_state:TLSDecrypt metadata.
  • ·CVE-2025-54254 affects Adobe Experience Manager Forms on JEE versions 6.5.23 and earlier only; cloud/SaaS deployments may have a different exposure profile.
  • ·CVE-2025-54254 is part of a chained exploit alongside CVE-2025-54253 (auth bypass + RCE) and CVE-2025-49533 (Java deserialization RCE); detection and patching should address all three vulnerabilities together.
