Official description

Incorrect Default Permissions vulnerability in Mitsubishi Electric Corporation FREQSHIP-mini for Windows versions 8.0.0 to 8.0.2 allows a local attacker to execute arbitrary code with system privileges by replacing service executable files (EXE) or DLLs in the installation directory with specially crafted files. As a result, the attacker may be able to disclose, tamper with, delete, or destroy information stored on the PC where the affected product is installed, or cause a Denial of Service (DoS) condition on the affected system.

The underlying weakness: Incorrect Default Permissions

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

How developers prevent this class of flaw

  • The architecture needs to access and modification attributes for files to only those users who actually require those actions.
  • 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.
