CVE-2024-36227
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 6.5.20 and earlier are affected by a DOM-based Cross-Site Scripting (XSS) vulnerability. This vulnerability could allow an attacker to execute arbitrary JavaScript code in the context of the victim's browser session. Exploitation of this issue typically requires user interaction, such as convincing a user to click on a specially crafted link or to submit a malicious 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 · high confidenceAdobe Experience Manager versions 6.5.20 and earlier contain a DOM-based Cross-Site Scripting (XSS) vulnerability. The issue occurs when client-side JavaScript improperly handles user input from URL parameters or DOM elements, allowing an attacker to inject malicious scripts that execute in the victim's browser session.

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.
-
Determine installed AEM versionLocate the version file in the AEM installation directory (typically in crx-quickstart/conf or check the manifest file), or access the AEM Web Console (Help > System Information > Version) to identify the exact version numberAffected if The version is 6.5.20 or earlier, or the version is earlier than the 2024.5 release train (e.g., versions like 2024.1, 2024.2, 2024.3, 2024.4)
-
Identify client-side URL parameter handlingReview custom client-side JavaScript code that reads values from URL parameters (such as location.search, URLSearchParams, or document.referrer) and outputs them to the DOM without proper sanitizationAffected if Custom or third-party JavaScript code processes URL parameters and renders them directly into HTML elements without encoding or validation
-
Check for DOM element manipulation from untrusted sourcesAudit client-side scripts that extract data from DOM elements (such as input fields, data attributes, or JSON stored in HTML) and insert that content into other parts of the page using innerHTML, outerHTML, or similar methodsAffected if Scripts take values from user-accessible DOM sources and insert them into the page using unsafe methods without sanitization
-
Verify CSP header configurationInspect the HTTP response headers for Content-Security-Policy headers. Check AEM core configuration (Adobe Granite CSRF Filter and Adobe Granite CSP Filter) or custom dispatcher configurations for CSP rulesAffected if No CSP header is present, or the CSP allows unsafe-inline scripts, which would permit the XSS payload to execute even if the vulnerable code path exists
You are affected if your AEM version is 6.5.20 or earlier, or below 2024.5, and your application processes URL parameters or DOM data client-side without sanitization and lacks CSP protection.
Generated from the published advisory. Verify against your own configuration.
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 · scoped6.5.212024.5
Upgrade to Adobe Experience Manager version 6.5.21 or later to obtain the vendor patch. Additionally, implement Content Security Policy (CSP) headers to provide defense-in-depth protection against XSS attacks.
AEM 6.5.21 or AEM 2024.5 (depending on your release line)
- Identify your current Adobe Experience Manager version by checking the AEM product information in the system console or version.properties file
- Determine which release line you are on: AEM 6.5.x or the 2024.x release train
- For AEM 6.5.x users: Plan upgrade to version 6.5.21 or later
- For AEM 2024.x users: Plan upgrade to version 2024.5 or later
- Review Adobe's official upgrade documentation for AEM before proceeding
- Apply the upgrade in a non-production environment first and verify all custom components function correctly
- After testing, schedule a maintenance window and deploy the upgrade to production
- Verify the XSS vulnerability is remediated by confirming the fix is applied
