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 version 6.5.14 (and earlier) is affected by a reflected Cross-Site Scripting (XSS) vulnerability. If a low-privileged 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

Reflected Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager version 6.5.14 and earlier allows low-privileged attackers to inject malicious JavaScript via URL parameters. When victims are convinced to visit a crafted URL referencing a vulnerable page, the malicious script executes within the context of the victim's browser.

MitigationUpgrade to Adobe Experience Manager version 6.5.15 or later which contains the patched version. Additionally, implement robust input validation and output encoding on user-supplied parameters before rendering them in HTML responses.

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. Check AEM version number
    Access the AEM System Information console at /system/console/vmstat or query the /crx/packmgr/service.jsp version endpoint. Alternatively, check the manifest file in the AEM installation directory for the exact version string.
    Affected if The installed version is lower than 6.5.15.0 (for AEM 6.x) or the version string indicates a release older than the October 2022 Cloud Service update (before 2022.10.0).
  2. Identify reflected URL parameters in responses
    Manually test your AEM pages by appending test values to URL parameters (such as ?test=123) and inspecting the page source to verify whether the parameter values appear unmodified in the HTML response without proper encoding.
    Affected if Any user-supplied URL parameter values are reflected in the rendered HTML page without being HTML-encoded, indicating a potential XSS vector.
  3. Verify low-privileged user access
    Confirm that unauthenticated or low-privilege users (such as those with standard content-author or read-only roles) can access the pages that accept URL parameters.
    Affected if Low-privilege users can access pages that accept and reflect URL parameters in the response, allowing the attack to be carried against victims with higher privileges.

You are affected if your AEM installation is version 6.5.14.0 or earlier (or AEM Cloud Service pre-dating the 2022.10.0 release) AND your pages reflect URL parameters in the HTML response without encoding, enabling attackers to execute malicious JavaScript in victim browsers via crafted URLs.

Upgrade available Upgrade to 6.5.15.0 / 2022.10.0 or later
Fixed in 6.5.15.02022.10.0
Interim mitigation

Upgrade to Adobe Experience Manager version 6.5.15 or later which contains the patched version. Additionally, implement robust input validation and output encoding on user-supplied parameters before rendering them in HTML responses.

Recommended fix High confidence

Adobe Experience Manager 6.5.15.0 (on-premise) or AEM Cloud Service 2022.10.0

  1. Plan and schedule the upgrade to avoid business disruption
  2. Review Adobe Experience Manager 6.5.15.0 release notes for any changes or known issues
  3. Back up the current AEM instance and database
  4. Test the upgrade in a staging or development environment before applying to production
  5. Upgrade Adobe Experience Manager to version 6.5.15.0 or later (for on-premise)
  6. For Cloud Service customers, verify the environment is on version 2022.10.0 or later
  7. Validate the fix by testing that the reflected XSS vulnerability is no longer exploitable
  8. Deploy the upgraded version to production
Caveat Point releases typically have minimal breaking changes, but review release notes and test in non-production first
