CVE-2024-43740
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 · high confidenceA stored Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager versions 6.5.21 and earlier allows authenticated attackers to inject malicious JavaScript into vulnerable form fields. The malicious payload persists in the system and executes when other users browse to pages containing the compromised form fields.

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.
-
Check your AEM versionAccess the AEM Welcome page or check the system/console info to identify the installed Adobe Experience Manager versionAffected if Version is below 6.5.22.0 or below 2024.11.0
-
Identify forms that accept user inputReview your AEM instance for any form components or Adaptive Forms that collect user-submitted dataAffected if Forms accepting user input are present in the system
-
Check form field input validation settingsInspect the configuration of form fields to determine if input validation and output encoding are implemented on submitted dataAffected if Form fields lack input validation or output encoding on stored data
-
Review custom form component codeExamine any custom form components or overlays for proper server-side output encoding when rendering stored form dataAffected if Custom components render user-submitted content without encoding
You are affected if running AEM version below 6.5.22.0 or below 2024.11.0 AND your forms store and display user input without proper validation and 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
Update Adobe Experience Manager to version 6.5.22 or later. Additionally, implement input validation and output encoding on form fields as a defense-in-depth measure.
AEM 6.5.22.0 or AEM as a Cloud Service 2024.11.0
- Identify the current Adobe Experience Manager version in use
- If running AEM 6.5.x, upgrade to version 6.5.22.0 or later
- If running AEM as a Cloud Service, upgrade to version 2024.11.0 or later
- After upgrade, verify the XSS vulnerability is resolved by testing form fields that previously allowed script injection
