CVE-2019-8084
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, 6.4, 6.3 and 6.2 have a reflected cross site scripting vulnerability. Successful exploitation could lead to sensitive information disclosure.
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 confidenceThis is a reflected cross-site scripting (XSS) vulnerability in Adobe Experience Manager versions 6.2 through 6.5. The vulnerability allows attackers to inject malicious scripts through crafted URLs that are reflected back by the server without proper sanitization, potentially leading to session hijacking or sensitive information disclosure via cookie theft or credential harvesting.

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 installed Adobe Experience Manager versionAccess the AEM Web Console by navigating to /system/console/status-productinfo or check the 'About Adobe Experience Manager' section in the AEM welcome page. The version number will be displayed in the product information.Affected if The installed version matches 6.2, 6.3, 6.4, or 6.5 exactly.
-
Confirm AEM is accessible and runningVerify the AEM instance is reachable by attempting to access the login page or any public-facing AEM path. If the server responds normally, the application is active.Affected if The server responds and AEM is running, combined with being on an affected version from step 1.
-
Test for reflected XSS in URL parametersSubmit a benign test payload such as a simple script tag or alert command as a query parameter to various AEM endpoints (for example: ?test=<script>alert(1)</script>). Observe whether the payload is reflected back in the response without encoding or sanitization.Affected if The submitted payload appears verbatim in the HTML response without being escaped or encoded.
-
Review HTTP response headers for security controlsCapture the HTTP response headers from AEM pages using browser developer tools or a tool like curl. Look for presence or absence of X-XSS-Protection header and Content-Security-Policy headers that might mitigate XSS.Affected if No anti-XSS headers are present or they are configured permissively, making reflected XSS more likely to succeed.
If the installed AEM version is exactly 6.2, 6.3, 6.4, or 6.5 and URL parameters are reflected in responses without sanitization, the environment is affected by CVE-2019-8084.

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.
From vendor dataApply the official Adobe security patch for CVE-2019-8084 when available, and implement output encoding and input validation on affected endpoints as an interim measure. Consider deploying a WAF rule to block XSS attack patterns.
