CVE-2018-12809
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAdobe Experience Manager versions 6.4 and earlier have a Server-Side Request Forgery vulnerability. Successful exploitation could lead to sensitive information disclosure.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA Server-Side Request Forgery (SSRF) vulnerability in Adobe Experience Manager versions 6.4 and earlier allows unauthenticated attackers to make the server perform requests to internal or external resources, potentially exposing sensitive data from internal services or the local network.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify AEM installation and versionLocate the AEM installation directory and check the version.properties file or use the AEM Web Console (access /system/console/status-productinfo) to determine the installed versionAffected if The installed version is 6.4.0 or any version earlier than 6.4.0 (6.3.x, 6.2.x, 6.1.x, 6.0.x, or earlier)
-
Confirm AEM is accessible over the networkDetermine if the AEM publish or author instance ports (typically 4502, 4503, or 80/443) are reachable from untrusted networks by reviewing firewall rules, load balancer configurations, or network ACLsAffected if AEM is directly exposed to the internet or accessible from untrusted internal networks without proper network segmentation
-
Identify web endpoints accepting external URLsReview deployed applications and custom code for servlets, filters, or components that accept URL parameters and could trigger server-side requests. Check the AEM Sling servlet registrations under /bin, /apps, and /system/pathsAffected if Any web interface, API endpoint, or custom component that accepts URL input and makes server-side requests is exposed and accessible to unauthenticated users
-
Check for unauthenticated access to vulnerable interfacesTest whether anonymous or unauthenticated access is permitted to the AEM instance by attempting to reach common endpoints without providing credentialsAffected if Anonymous or unauthenticated users can access AEM web interfaces or APIs that handle URL-based requests
A user is affected if their AEM installation is version 6.4.0 or earlier, is network-accessible to untrusted parties, and exposes any unauthenticated web interface that processes external URL requests.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to Adobe Experience Manager 6.5 or later and apply available security patches. Additionally, enforce strict network segmentation and restrict outbound connections from the AEM server to mitigate SSRF impact.
