CVE-2024-43743
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 stored Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim’s browser when they browse to the page containing the vulnerable field.
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 confidenceAdobe Experience Manager versions 6.5.21 and earlier are affected by a stored Cross-Site Scripting (XSS) vulnerability in form fields. Attackers can inject malicious JavaScript into vulnerable form inputs, which persists on the server. When legitimate users browse to pages containing these compromised fields, the malicious script executes in their browsers.

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 versionNavigate to AEM Welcome page > Tools > Operations > Diagnosis, or access /system/console/systeminfo to view the version. Alternatively, check the jar file name or version.properties in the crx-quickstart folder.Affected if The installed version is 6.5.21 or earlier, or below 2024.11.0 for the newer release track.
-
Locate Form components in useCheck /apps for custom form components (form, textfield, textarea, dropdown, datepicker) in your project. Review the HTL/JSP templates in /apps/your-project/components to identify where form fields are rendered.Affected if Custom form components exist that may not implement proper output encoding for all input fields.
-
Examine form field submission handlingReview the form submission servlets and models in your codebase. Check how form data is handled - look for getParameter calls and how values are stored to repositories or databases.Affected if Form inputs are stored without sanitization or validation before persistence.
-
Review existing stored form dataQuery the repository using CRXDE Lite or AEM Developer Mode. Navigate to /content or /etc/forms to inspect stored form submissions. Check for any unusual script tags in field values.Affected if Any stored form data contains unencoded HTML/script content that could execute.
You are affected if your AEM version is below 6.5.22.0 or below 2024.11.0 AND you have custom form components that accept user input without proper output encoding.
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 · scoped6.5.22.02024.11.0
Implement strict input validation and output encoding for all form fields in AEM. Consider adding Content Security Policy (CSP) headers to mitigate XSS execution. Upgrade to AEM version 6.5.22 or later if a patch is available.
Adobe Experience Manager 6.5.22.0 or later, or 2024.11.0 or later
- Upgrade Adobe Experience Manager to version 6.5.22.0 or later for the 6.5.x release line
- Alternatively, upgrade to version 2024.11.0 or later for the newer release line
- After upgrade, verify that the stored XSS vulnerability in form fields is remediated by testing malicious script injection in affected form fields
