CVE-2023-29304
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 6.5.16.0 (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 confidenceReflected Cross-Site Scripting (XSS) vulnerability in Adobe Experience Manager versions 6.5.16.0 and earlier. An attacker can craft a malicious URL containing JavaScript payload that gets reflected back and executed in victim's browser when convinced to visit the vulnerable page.

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 if Adobe Experience Manager is deployedCheck your environment for AEM instances by reviewing installed web applications, checking for 'adobe' or 'aem' in application names, or inspecting running processes on application servers.Affected if AEM is present in the environment
-
Determine the installed AEM versionAccess the AEM System Information console at /system/console/bundles or check the version.properties file in the AEM installation directory. For AEM Cloud Service, review the version information in the Cloud Manager or release notes.Affected if The version is < 6.5.17.0 for AEM or < 2023.4 for AEM Cloud Service
-
Verify the affected component is accessibleConfirm that the AEM web application is accessible over HTTP/HTTPS and that public-facing or internal endpoints are reachable.Affected if The AEM instance is accessible and the vulnerable endpoint can be reached
-
Identify if user input reflection is possibleTest whether URL parameters or form inputs are reflected in the response without proper encoding. Craft a test request with a benign payload (such as ?test=<script>alert(1)</script>) and observe if the script tag appears unencoded in the response.Affected if User-supplied input is reflected back in the HTTP response without sanitization
You are affected if Adobe Experience Manager is running with version < 6.5.17.0 (AEM) or < 2023.4 (Cloud Service) and the application reflects URL parameters or other user input in responses without encoding.

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 · scoped6.5.17.02023.4
Apply available Adobe security patches for AEM; implement proper input validation and output encoding on affected endpoints; deploy Content-Security-Policy headers as defense-in-depth.
AEM on-prem: 6.5.17.0+ | AEM Cloud Service: 2023.4+
- Identify the Adobe Experience Manager deployment type (AEM on-premises or AEM Cloud Service)
- For AEM on-premises: Upgrade Adobe Experience Manager to version 6.5.17.0 or later
- For AEM Cloud Service: Upgrade to version 2023.4 or later
- After upgrade, verify the patch was applied by checking the AEM version information
- Test that the reflected XSS vulnerability is no longer present in the updated version
