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 · unedited
Adobe Experience Manager versions 6.5.20 and earlier are affected by a reflected Cross-Site Scripting (XSS) vulnerability. If an attacker is able to convince a victim to visit a URL referencing a vulnerable page, malicious JavaScript content may be executed within the context of the victim's browser.

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 confidence

Adobe Experience Manager versions 6.5.20 and earlier contain a reflected XSS vulnerability where malicious JavaScript can be injected through URL parameters. When a victim is tricked into visiting a specially crafted URL pointing to a vulnerable AEM page, the attacker's JavaScript executes within the victim's browser context.

MitigationUpdate Adobe Experience Manager to version 6.5.21 or later to receive the security patch. As a temporary measure, implement URL parameter validation and output encoding on affected endpoints.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Determine AEM version installed
    Access the AEM Welcome page or check the product version via the system information console at /system/console/configMgr or by reviewing the crx-quickstart folder for version files
    Affected if The installed version is before 6.5.21 or before the 2024.5 release (versions prior to the fixed releases)
  2. Identify exposed AEM web endpoints
    Review the AEM publish and author instances for publicly accessible pages that process URL parameters (common paths include content/dam, content/geometrixx, or custom servlet endpoints)
    Affected if URL parameter handling endpoints are exposed without proper validation on unpatched versions
  3. Test for reflected parameter reflection
    Use a browser or curl to request a suspected endpoint with a test parameter value such as ?testparam=<script>alert(1)</script> and observe if the value is reflected back in the response without encoding
    Affected if The parameter value is reflected verbatim in the HTML response without being sanitized or encoded
  4. Verify default CSP or XSS protections
    Check AEM Dispatcher configuration and any custom filter configurations at /system/console/config for XSS protection filters, and review the Content Security Policy headers on responses
    Affected if No XSS protection filters are active and the server returns unencoded user input in URL parameters

A user is affected if their AEM installation is version 6.5.20 or earlier (or pre-2024.5) and URL parameters from requests are reflected in responses without sanitization, allowing script injection.

Upgrade available Upgrade to 6.5.21 / 2024.5 or later
Fixed in 6.5.212024.5
Interim mitigation

Update Adobe Experience Manager to version 6.5.21 or later to receive the security patch. As a temporary measure, implement URL parameter validation and output encoding on affected endpoints.

Recommended fix High confidence

Adobe Experience Manager 6.5.21 or later, or 2024.5 release or later

  1. 1. Back up the current Adobe Experience Manager instance including all content and configurations
  2. 2. Review the Adobe Experience Manager 6.5.21 release notes for any required pre-upgrade steps or migration tasks
  3. 3. Download Adobe Experience Manager 6.5.21 (or newer 6.5.x version) from the Adobe distribution portal
  4. 4. Install the new version following Adobe's standard upgrade documentation for your deployment type (jar file or combined jar)
  5. 5. Apply any additional hotfixes or service packs released after 6.5.21
  6. 6. Verify the upgrade by logging into AEM and confirming all custom applications function correctly
  7. 7. Test that the reflected XSS vulnerability is no longer exploitable by attempting the previously vulnerable URL pattern
Caveat Review AEM 6.5.21 release notes for any compatibility breaking changes with custom code or third-party integrations before upgrading
