CVE-2021-33095
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnquoted search path in the installer for the Intel(R) NUC M15 Laptop Kit Keyboard LED Service driver pack before version 1.0.0.4 may allow an authenticated user to potentially enable escalation of privilege via local access.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceAn unquoted search path vulnerability exists in the Intel NUC M15 Laptop Kit Keyboard LED Service driver pack installer before version 1.0.0.4. When a service executable path contains spaces and isn't properly quoted, Windows may attempt to execute a malicious binary from an intermediate path directory, allowing an authenticated local user to escalate privileges.

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 the Keyboard LED Service is installedRun 'sc query' or query the Windows registry at HKLM\SYSTEM\CurrentControlSet\Services for a service related to Intel NUC M15 Keyboard LEDAffected if No service named 'IntelNUC15KeyboardLEDService' or similar is found - the system is not affected because the vulnerable service is not installed
-
Query the service binary pathRun 'sc qc <service_name>' to retrieve the service configuration and examine the BINARY_PATH_NAME fieldAffected if The BINARY_PATH_NAME contains spaces and is not surrounded by quotation marks - the service is vulnerable to unquoted path injection
-
Inspect the executable path for spacesManually inspect the path returned from the service query. Look for directories with spaces in their names (e.g., 'Program Files' or 'Intel Corporation') that are not enclosed in quotesAffected if The path contains unquoted directory names with spaces, allowing potential binary injection from intermediate path directories
-
Compare the driver pack versionCheck the installed version of the Intel NUC M15 Keyboard LED Service Driver Pack via 'wmic product get name,version' or by reviewing the installed programs list in Control PanelAffected if The installed version is lower than 1.0.0.4, indicating the vulnerable unquoted path issue is present
The system is affected if the Intel NUC M15 Keyboard LED Service is installed, its executable path contains unquoted spaces, and the driver pack version is below 1.0.0.4.
