An incorrect default permission [CWE-276] vulnerability in FortiClient (Windows) versions 7.0.0 through 7.0.6 and 6.4.0 through 6.4.8 and FortiConverter (Windows) versions 6.2.0 through 6.2.1, 7.0.0 and all versions of 6.0.0 may allow a local authenticated attacker to tamper with files in the installation folder, if FortiClient or FortiConverter is installed in an insecure folder.

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.
