dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Dell SupportAssist is installedCheck Windows Programs and Features for 'Dell SupportAssist' or look in C:\Program Files\Dell\SupportAssist for installation directory. On Linux, check /opt/Dell/SupportAssist or use package manager.Affected if Dell SupportAssist is present on the system
-
Determine installed SupportAssist versionRight-click the application in Programs and Features to view version, or check the version file in the installation directory (often version.txt or in the main executable properties).Affected if Version is blank or cannot be determined for comparison
-
Compare version against vulnerable rangesIf SupportAssist for Business PCs is installed, check if version < 3.3.0. If SupportAssist for Home PCs is installed, check if version < 3.12.3. Note the product type from the program name in Programs and Features.Affected if Version is below 3.3.0 for Business PCs or below 3.12.3 for Home PCs
-
Check if screen sharing support feature is configuredOpen SupportAssist and navigate to settings or check if the screenmeet/screen sharing component is listed as enabled in the application or its configuration files.
