CVE-2018-12441

The CorsairService Service in Corsair Utility Engine is installed with insecure default permissions, which allows unprivileged local users to execute arbitrary commands via modification of the CorsairService BINARY_PATH_NAME, leading to complete control of the affected system. The issue exists due to the Windows Everyone group being granted SERVICE_ALL_ACCESS permissions to the CorsairService Service.

Weakness

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

Affected Software

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.
