CVE-2022-42356
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 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 confidenceAdobe Experience Manager version 6.5.14 and earlier is affected by a reflected Cross-Site Scripting (XSS) vulnerability. User-supplied input in the URL is not properly sanitized before being returned to the victim's browser, allowing execution of arbitrary JavaScript code within the context of the victim's session.

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 version via welcome page or system informationAccess the AEM welcome page (/) and locate the version number typically displayed in the footer, or access the System Information console at /system/console/systeminfo if you have administrative accessAffected if The displayed version is 6.5.14.0 or earlier, or the version cannot be confirmed as 6.5.15.0 or later
-
Query AEM package manager for version detailsAccess /crx/packmgr/service.jsp or /libs/granite/package/content.jsp to retrieve detailed package and product version informationAffected if The returned version information shows a build version lower than 6.5.15.0
-
Check AEM Cloud Service release versionIf running AEM as a Cloud Service, check the Cloud Manager environment details or the Adobe IMS version metadata for the release date and version identifierAffected if The Cloud Service version is older than the 2022.10.0 release (October 2022)
-
Verify the XSS vector exists via URL parameter reflectionTest a non-sensitive AEM URL by appending a harmless test string such as ?testparam=<script>alert(1)</script> and observe whether the parameter value is reflected unescaped in the response HTMLAffected if The URL parameter value is reflected directly in the page source without HTML encoding
You are affected if your AEM version is below 6.5.15.0 (for AEM 6.5) or below 2022.10.0 (for AEM Cloud Service) AND URL parameters are being reflected without sanitization in your environment.
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 · scoped6.5.15.02022.10.0
Apply Adobe security patch (upgrade to AEM 6.5.15 or later) to remediate the vulnerability; alternatively, implement URL parameter validation and output encoding as a compensating control until patching is feasible.
AEM 6.5.15.0 (on-premise) or AEM Cloud Service 2022.10.0
- Identify the current Adobe Experience Manager version in use (on-premise or Cloud Service)
- For Experience Manager on-premise: Upgrade to version 6.5.15.0 or later
- For Experience Manager Cloud Service: Ensure the version is 2022.10.0 or later
- After upgrade, verify the XSS vulnerability is resolved by testing that URL parameters are properly sanitized
- Confirm normal AEM functionality works as expected post-upgrade
