CVE-2024-43720
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 6.5.21 and earlier are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability that could be exploited to execute arbitrary code in the context of the victim's browser session. By manipulating the DOM environment in the victim's browser, an attacker can inject malicious scripts that are executed by the victim's browser. Exploitation of this issue requires user interaction, typically in the form of following a malicious link.
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 · high confidenceAdobe Experience Manager versions 6.5.21 and earlier are affected by a DOM-based Cross-Site Scripting vulnerability. Attackers can manipulate the DOM environment in victim's browsers to inject malicious scripts that execute within the user's session, requiring victim interaction (clicking a malicious link).

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.
-
Confirm AEM installation and locate version fileLocate the AEM installation directory and find the version.properties file (typically in crx-quickstart/conf or app/cq author), or access the AEM System Information console at /system/console/configMgr or check the AEM welcome page footer for version displayAffected if The file cannot be found or AEM is not running, meaning AEM is not present in this environment
-
Determine installed AEM versionRead the version number from version.properties or the AEM welcome page. Look for a version string in the format 6.5.x.x or 2024.x.xAffected if The installed version is lower than 6.5.22.0 or lower than 2024.11.0, placing it within the affected range
-
Verify AEM is accessible and serving contentConfirm the AEM instance is running by accessing the author or publish instance URLs (typically port 4502 for author, 4503 for publish) and checking that pages load successfullyAffected if The instance is not accessible, meaning the vulnerability cannot be exploited against this deployment at this time
-
Identify if user-generated content features are in useReview enabled AEM components and templates, particularly any that accept and render user-supplied HTML or JavaScript, such as custom components, comment systems, or form submissions that store data in AEMAffected if Components accepting unsanitized user input are present and accessible without authentication, creating potential DOM XSS injection points
The environment is affected if AEM is installed and the installed version falls below 6.5.22.0 or 2024.11.0, with accessible features that allow script injection into the DOM.

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.
dbcve · scoped6.5.22.02024.11.0
Apply the vendor patch by updating Adobe Experience Manager to version 6.5.22 or later to remediate the DOM-based XSS vulnerability.
AEM 6.5.22.0 (on-premise) or AEM as a Cloud Service 2024.11.0
- Identify your current Adobe Experience Manager version and deployment type (AEM 6.5.x on-premise or AEM as a Cloud Service)
- For AEM 6.5.x on-premise: Upgrade to version 6.5.22.0 or later
- For AEM as a Cloud Service: Ensure your environment is updated to the 2024.11.0 release or later
- After upgrading, verify the DOM-based XSS vulnerability is resolved by testing the previously vulnerable endpoints
- Review Adobe's release notes for 6.5.22.0 or 2024.11.0 for any additional security hardening applied
