CVE-2022-42366
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 · moderate confidenceReflected XSS vulnerability in Adobe Experience Manager 6.5.14 and earlier allows a low-privilege attacker to inject malicious JavaScript into a URL parameter. When a victim clicks the crafted URL, the malicious content is reflected back and executed in the victim's browser context.

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 Adobe Experience Manager versionLog into AEM as admin and navigate to the AEM Welcome page, or access the System Console at /system/console/bundles and look for the version information in the bundle details or the productinfo endpointAffected if The installed version is below 6.5.15.0 for AEM on-premise or below 2022.10.0 for AEM Cloud Service
-
Verify AEM Cloud Service release versionIf using AEM Cloud Service, check the release version through the Cloud Manager UI or Adobe Admin Console to confirm the specific release numberAffected if The Cloud Service release is earlier than the 2022.10.0 release
-
Identify accessible URL parametersReview custom AEM components, sling selectors, or extensions that process URL parameters. Check any custom servlets or JSP files that read request parameters and render them in outputAffected if Custom code or extensions handle URL parameters without proper output encoding
-
Inspect XSS filter configurationNavigate to the XSSAPI configuration in AEM at /system/console/configMgr and review the XSS protection rules. Check if the 'Reflected XSS' protection is enabled and properly configuredAffected if XSS filters are disabled or misconfigured, allowing unencoded parameter reflection
Your environment is affected if you are running AEM on-premise version below 6.5.15.0 or AEM Cloud Service below the 2022.10.0 release, especially if custom URL parameters are processed without 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 · scoped6.5.15.02022.10.0
Apply Adobe security patch (6.5.15 or later) to address the vulnerability. For immediate workarounds, implement URL parameter validation and output encoding on affected endpoints, or deploy a WAF rule to filter malicious XSS payloads.
Adobe Experience Manager 6.5.15.0 (on-premise) or AEM Cloud Service 2022.10.0+
- 1. Identify your current Adobe Experience Manager deployment type (on-premise or Cloud Service)
- 2. For on-premise AEM: Schedule maintenance window and backup current instance
- 3. For on-premise AEM: Download and install AEM 6.5.15.0 or later from Adobe Software Distribution
- 4. For AEM Cloud Service: Ensure deployment pipeline uses version 2022.10.0 or later
- 5. After upgrade, verify the XSS vulnerability is resolved by testing the previously vulnerable endpoint
- 6. Validate that custom code and integrations function correctly post-upgrade
