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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Microsoft Partner Center usage
    Identify if your organization uses Partner.Microsoft.com for partner account management, CSP (Cloud Solution Provider) operations, or partner portal access. Check saved credentials, browser bookmarks, or SSO configurations for references to Partner.Microsoft.com.
    Affected if Your organization has an active Microsoft Partner Center account or uses the partner portal for business operations.
  2. Review sign-in logs for unauthorized access
    Access Microsoft Partner Center admin portal and navigate to the Activity Log or Sign-in Logs section. Look for sign-in events from IP addresses or locations that do not match your organization's known users or locations, particularly those occurring outside normal business hours.
    Affected if There are successful sign-in events from unrecognized accounts or suspicious IP addresses that you cannot attribute to legitimate partner users.
  3. Check for privilege escalation indicators
    In Partner Center, navigate to User management or Account settings. Review audit logs for role changes, permission modifications, or administrative actions performed by accounts that previously had lower privilege levels. Look for entries where the actor does not match your known administrator roster.
    Affected if Role or permission changes exist in the audit log that were performed by accounts lacking prior administrative privileges, or by unknown users.
  4. Identify unexpected user accounts or role assignments
    Review the full list of user accounts and their assigned roles in Partner Center user management. Cross-reference against your organization's documented partner user list. Look for newly added users, particularly those with Admin Agent or Global Admin roles.
    Affected if There are user accounts present in Partner Center that your organization did not create, or role assignments that were not authorized by your internal processes.

Your organization is affected if it uses Microsoft Partner Center and evidence shows unauthorized access, privilege escalation, or unexpected administrative changes in the portal.
