Insecure inherited permissions in some Intel(R) Ethernet tools and driver install software may allow an authenticated user to potentially enable escalation of privilege via local access.
Weakness
A product defines a set of insecure permissions that are inherited by objects that are created by the program.
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.
