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.
-
Confirm Dell SupportAssist is installedOpen Programs and Features in Control Panel or use 'Get-ItemProperty' in PowerShell to query the registry under HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall for entries containing 'SupportAssist', or run 'wmic product get name,version' to list installed software.Affected if Dell SupportAssist is not present on the system, the vulnerability does not apply.
-
Identify the SupportAssist variantReview the software name in Programs and Features or the uninstall registry entry. Look for 'Dell SupportAssist for Business PCs' or 'Dell SupportAssist for Home PCs' in the displayed name.Affected if The variant must be identified to apply the correct version threshold.
-
Retrieve the installed version numberIn Programs and Features, note the version column for the SupportAssist entry. Alternatively, run 'wmic product where "name like '%SupportAssist%'" get name,version' or check the Uninstall registry key for the Version value.Affected if The version number is required to determine if it falls within the affected range.
-
Compare version against affected rangesFor Business PCs: check if version is <= 3.2.0. For Home PCs: check if version is <= 3.11.4. If the exact version cannot be determined, inspect the program's About or Help section within the application.Affected if Version <= 3.2.0 for Business PCs or <= 3.11.4 for Home PCs indicates the system is affected by this privilege escalation vulnerability.
The system is affected if Dell SupportAssist is installed and the installed version falls within the vulnerable ranges (3.2.0 and prior for Business PCs, 3.11.4 and prior for Home PCs).
