Incorrect default permissions in the installer for the Intel(R) NUC M15 Laptop Kit HID Event Filter driver pack before version 2.2.1.383 may allow an authenticated user to potentially enable escalation of privilege via local access.

Weakness

During installation, installed file permissions are set to allow anyone to modify those files.

Affected Software

Name Vendor Start Version End Version
Nuc_m15_laptop_kit_hid_event_filter_driver_pack Intel * 2.2.1.383 (excluding)

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
