CVE-2024-53963
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 a low privileged 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 access a manipulated link or input data into a vulnerable page.
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 confidenceDOM-based Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager versions 6.5.21 and earlier allows low-privilege attackers to inject malicious scripts through manipulated DOM elements via crafted URLs or user input, executing in victims' browser sessions when pages render.

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 product versionAccess the AEM system information console at /system/console/status-productinfo or check the version.properties file in the AEM installation directory to retrieve the installed version numberAffected if The displayed version is below 6.5.22 or below 2024.11.0
-
Confirm AEM edition and buildVerify the exact version string includes the build number and hotfix pack level if applicable, as shown in the AEM Welcome page footer or via the CRXDE Lite package manager version displayAffected if Version shows 6.5.21 or earlier, or shows a 2024 version prior to the November 2024 release
-
Determine exposure to user input vectorsReview whether the AEM instance uses Forms, Community features, or any custom components that accept and render user-submitted content in the DOM without sanitizationAffected if User-generated content or URL parameters are rendered directly in page output without proper encoding
The environment is affected if the installed AEM version is below 6.5.22 or below 2024.11.0 and the instance renders user input or URL parameters in the DOM without sanitization.

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 · scoped6.5.222024.11.0
Apply Adobe's vendor patch by upgrading AEM to version 6.5.22 or later to address the DOM-based XSS vulnerability.
Adobe Experience Manager 6.5.22 (or later) for 6.5.x branch; 2024.11.0 (or later) for 2024.x cloud branch
- Upgrade Adobe Experience Manager to version 6.5.22 or later for the 6.5.x on-premise release line
- If using the cloud-based 2024 release line, upgrade to version 2024.11.0 or later
- After upgrading, verify that the XSS vulnerability is resolved by testing with crafted URLs or inputs that previously triggered the issue
- Ensure proper testing in a staging environment before deploying the upgrade to production
