CVE-2024-52839
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 by an attacker to execute arbitrary code in the context of the victim's browser session. By manipulating a DOM element through a crafted URL or user input, the attacker can inject malicious scripts that run when the page is rendered. This type of attack requires user interaction, as the victim would need to visit a malicious link or input data into a compromised form.
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 DOM-based Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager versions 6.5.21 and earlier allows attackers to inject malicious scripts through manipulated DOM elements via crafted URLs or user input, which execute in the victim's browser session when the page renders.

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 the installed AEM versionLocate the AEM version information in the product About page (Help > About Adobe Experience Manager) or check the version.properties file in the crx-quickstart folder. Compare the version number to the affected ranges: below 6.5.22.0 or below 2024.11.0.Affected if The installed version is AEM 6.5.21 or earlier, or any version before 2024.11.0, and the application handles user input in DOM elements.
-
Determine if user input flows into DOM manipulationReview custom components, Sightly/JSP templates, and client-side JavaScript that accept URL parameters or user-submitted data and render them directly into HTML without output encoding. Search codebase for patterns where request parameters or resource API responses are appended to innerHTML, outerHTML, or document.write().Affected if The application contains components that render user-supplied data into the DOM without proper sanitization or encoding.
-
Audit custom OSGi bundles or third-party integrationsExamine any custom OSGi bundles or integrations that handle DOM operations. Check if these bundles expose endpoints that accept user input and manipulate DOM elements on rendered pages.Affected if Custom code or third-party integrations process and render user input into DOM elements without input validation or output encoding.
-
Review content validation and input filtering configurationsCheck the OSGi Configuration Manager for any custom input validation filters or Content Security Policy (CSP) configurations. Identify if there are gaps in input validation for fields that feed into DOM rendering.Affected if Input validation rules are absent, disabled, or do not filter script injection patterns, and CSP headers are not enforced.
A system is affected if it runs any AEM version below 6.5.22.0 or below 2024.11.0 and contains custom components or configurations that render user-supplied data directly into the DOM without encoding or validation.

dbcve · scoped6.5.22.02024.11.0
Apply the Adobe vendor patch for AEM 6.5.21 or later, and implement output encoding and input validation for all user-supplied data before DOM manipulation.
AEM 6.5.22.0 (or later) / AEM Cloud Service 2024.11.0 (or later)
- 1. Identify the current Adobe Experience Manager version in use (check /system/console/about or the welcome screen)
- 2. If running AEM 6.5.x: Plan upgrade to version 6.5.22.0 or later
- 3. If running AEM as a Cloud Service: Plan upgrade to version 2024.11.0 or later
- 4. Perform a full backup of the AEM instance (repository, database, and configuration files)
- 5. Test the upgrade in a staging or development environment first
- 6. Execute the upgrade following Adobe's official upgrade documentation for your deployment type
- 7. After upgrade, verify the new version is installed correctly (check /system/console/about)
- 8. Validate that the DOM-based XSS vulnerability is resolved by testing the previously vulnerable vectors
