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.
-
Verify Intel Unite Cloud Service client is installedCheck the system for Intel Unite Cloud Service client installation. Look in standard program directories or use system inventory tools (e.g., Add/Remove Programs on Windows, package manager on Linux).Affected if The software is installed on the system
-
Identify installed version of Intel Unite Cloud Service clientLocate the application and retrieve its version information. Common methods include: right-clicking the application icon and selecting 'Properties' > 'Details', checking the executable file properties, or using command-line tools like 'wmic product get name,version' on Windows.Affected if The version cannot be determined or the software appears to be installed without clear version metadata
-
Compare installed version against vulnerable rangeTake the identified version number and compare it numerically to 4.2.12212. For version comparison, ensure you compare the full version string (e.g., 4.2.10000 is less than 4.2.12212).Affected if The installed version is less than 4.2.12212 (e.g., 4.2.10000, 4.1.x, 4.0.x)
-
Confirm local user authentication contextVerify that local user accounts exist on the system and that the Intel Unite Cloud Service client is accessible to authenticated local users. Check user account types and group memberships.Affected if Local authenticated users can access and interact with the Intel Unite client application
The environment is affected if Intel Unite Cloud Service client is installed with a version lower than 4.2.12212 and local authenticated users can access the application.
