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 Dynamics 365 Customer Engagement versionAccess the Dynamics 365 Administration Center (for online) or check the About page in the Dynamics 365 web client (Navigate to Settings > About). Alternatively, use PowerShell with the Dynamics 365 Admin module: Get-CrmOrganization -DeploymentType Online or check the installed version through the server's Programs and Features.Affected if The installed version is Microsoft Dynamics 365 version 9.0 exactly (9.0.x).
-
Verify web client access is enabledConfirm that the Dynamics 365 Web Client service is running and accessible. For on-premise deployments, check that the Dynamics 365 Website is published and accessible via IIS Manager or by attempting to access the organization's URL in a browser.Affected if The web client interface is accessible and users can interact with Dynamics 365 pages where XSS could be injected.
-
Check for suspicious web resources or custom scriptsReview custom web resources in Dynamics 365 (Navigate to Settings > Customizations > Customize the System > Web Resources). Look for any custom JavaScript web resources that may contain malicious scripts or have been modified. Export and inspect custom script files for unfamiliar code.Affected if Unrecognized or malicious JavaScript web resources exist, or if custom scripts contain suspicious encoding patterns typical of XSS payloads.
Your environment is affected if you are running Microsoft Dynamics 365 Customer Engagement version 9.0 and the web client interface is accessible to users.
