CVE-2024-43733
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 confidenceDOM-based Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager versions 6.5.21 and earlier allows attackers to inject malicious scripts into DOM elements via crafted URLs or user input. Exploitation requires user interaction such as clicking a malicious link or submitting compromised form data, with scripts executing in the victim's browser session context.

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 installed AEM versionAccess the AEM welcome page or execute: curl -s http://localhost:4502/crx/packmgr/service.jsp?cmd=version to retrieve the version number. Alternatively, check the product.info in the system console at /system/console/systeminfo.Affected if The displayed version is lower than 6.5.22.0 or lower than 2024.11.0 (for cloud/2024 releases).
-
Verify DOM reflection of URL parametersTest AEM pages by injecting common XSS probe strings (such as <script>alert(1)</script> or javascript:alert(1)) into URL parameters and form input fields. Observe if these strings appear unmodified in the page's HTML source without encoding.Affected if User-supplied input is rendered directly into the DOM without server-side output encoding or client-side sanitization.
-
Inspect Content Security Policy headersSend a request to your AEM instance (e.g., curl -I http://localhost:4502) and examine response headers for Content-Security-Policy or X-Content-Security-Policy headers.Affected if No CSP headers are present, or existing CSP allows inline scripts (unsafe-inline), indicating lack of defense-in-depth controls against DOM XSS.
You are affected if your AEM version is below 6.5.22.0 or below 2024.11.0 AND user input or URL parameters are reflected into the DOM without encoding, especially if no CSP headers are configured.
Generated from the published advisory. Verify against your own configuration.

dbcve · scoped6.5.22.02024.11.0
Upgrade Adobe Experience Manager to a version newer than 6.5.21 and implement output encoding/sanitization for all user-supplied data before rendering in the DOM. Consider adding Content Security Policy (CSP) headers as an additional defense-in-depth measure.
6.5.22.0 (for AEM 6.5) or 2024.11.0 (for AEM as a Cloud Service)
- Backup your Adobe Experience Manager instance and verify all data is properly backed up
- Review the Adobe Experience Manager 6.5.22.0 or 2024.11.0 release notes for any breaking changes or migration requirements
- Test the upgrade in a non-production/staging environment before applying to production
- Follow Adobe's official upgrade documentation to apply the upgrade to your AEM instance
- Verify the upgrade was successful and test critical workflows
