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.
-
Check if ZTE uSmartview or Zxcloud Irai is installedLook for uSmartview application in installed programs on Windows (Control Panel > Programs and Features) or search for 'uSmartview' in the system. Also check for 'Zxcloud Irai' in program listings.Affected if The application is present on the system
-
Locate the installed version of ZTE uSmartview or Zxcloud IraiRight-click the application shortcut and select 'Properties', then check the 'Details' tab for the version number. Alternatively, navigate to the installation directory (commonly C:\Program Files\ZTE\uSmartview or similar) and look for a version file or check the executable properties.Affected if Version cannot be determined or is not visible
-
Compare your installed version against the affected rangeIf you found a version number, verify whether it falls within the range: version >= 7.23.20 AND version < 7.25.43. Any version in this range is affected.Affected if Installed version is 7.23.20 or higher but lower than 7.25.43
-
Verify if the uSmartview service is runningOpen Task Manager or Services console (services.msc) and look for 'uSmartview' or 'ZTE Cloud PC' related services. Check if the process is active.Affected if The uSmartview service is currently running and exposed on the network
You are affected if ZTE uSmartview or Zxcloud Irai is installed with a version between 7.23.20 and 7.25.43 (inclusive of 7.23.20, exclusive of 7.25.43) and the service is running and network-accessible.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped7.25.43
Restrict network exposure of systems running uSmartview (e.g., firewall rules, network segmentation) and monitor for vendor security updates. Consider disabling uSmartview if not critically required until a patch is available.
7.25.43 or later
- Upgrade Zxcloud Irai to version 7.25.43 or later to remediate the vulnerability.
- Verify the upgrade by checking the client version through the uSmartview interface or support.zte.com.cn documentation.
- Test the upgraded client to confirm normal operation and that the memory corruption issue is resolved.
