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 Mi Connect Service APP is installedCheck device/application inventory for Xiaomi Mi Connect Service APP. On Android, go to Settings > Apps > All Apps and search for Mi Connect or Xiaomi Connect. On iOS, check installed apps for Mi Connect.Affected if Mi Connect Service APP is present on the device or system
-
Determine installed application versionOpen the Mi Connect Service APP, go to Settings > About > Version info, or view the app in the app store/Google Play Store to see the current installed version. Record the version number.Affected if Version number cannot be determined or is lower than vendor-published patched version (check Xiaomi security advisory for specific version)
-
Check if service is network-exposedReview network configuration and firewall rules. Check if Mi Connect Service is bound to external/network interfaces or if port forwarding/DMZ is configured on router for Xiaomi device management ports (commonly 18888, 54321, or vendor-specific ports).Affected if Service is accessible from external networks without VPN or proper network segmentation
-
Verify authentication configurationWithin Mi Connect Service APP settings, review account binding, login verification, and authentication settings. Check if any test mode or debug features are enabled that may bypass authentication.Affected if Authentication is disabled, in test mode, or improperly configured allowing unauthenticated access
User is affected if Mi Connect Service APP is installed AND (running an unpatched version OR exposed to untrusted networks with weak authentication settings).
