CVE-2022-34218
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 6.5.13.0 (and earlier) is affected by a reflected Cross-Site Scripting (XSS) vulnerability. If an 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. Exploitation of this issue requires low-privilege access to AEM.
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 XSS vulnerability in Adobe Experience Manager where malicious JavaScript can be injected via URL parameters. When victims visit a crafted URL referencing a vulnerable page, the script executes within their browser context. Exploitation requires low-privilege authenticated access to AEM.

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 AEM versionAccess the AEM welcome page or check the version via the system console (e.g., /system/console/bundles or /crx/packmgr/service.jsp) to retrieve the exact AEM version numberAffected if The installed version is 6.5.13.0 or any earlier version, or if it is any version below 6.5.14.0 where patches have not been applied
-
Confirm URL parameter reflectionReview the application logs or use a testing proxy to capture HTTP responses while submitting various URL parameters to AEM pages. Examine whether submitted parameter values are reflected back in the HTML response without proper encodingAffected if URL parameters are echoed back in responses without encoding, indicating the vulnerability is present
-
Identify unauthenticated or low-privilege access pathsCheck the AEM permission configuration for user groups and evaluate which endpoints accept unauthenticated or low-privilege (e.g., contributor, reader) requests. Test whether such requests can include custom URL parametersAffected if Low-privilege authenticated users can access pages that process URL parameters without validation, enabling the XSS attack vector
-
Test for reflected XSS in common parameter handlersUsing an authorized testing account, craft URLs with script payloads in common parameters (such as 'redirect', 'url', or 'path') and observe if the payload executes when the page loads in a browserAffected if The crafted JavaScript payload executes in the browser, confirming the reflected XSS vulnerability is exploitable
-
Verify security patch statusCheck the AEM package manager or hotfix list for installed security patches related to CVE-2022-34218. Look for patches in the version history or release notesAffected if No specific security patch for CVE-2022-34218 is installed, and the AEM version falls within the affected range
A user is affected if running Adobe Experience Manager version 6.5.13.0 or earlier with URL parameter reflection present and accessible to low-privilege authenticated users without the CVE-2022-34218 security patch applied.

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 dataImplement input validation and output encoding on all user-supplied URL parameters to neutralize script injection. Apply AEM security patches to version 6.5.13.0 or later.
