CVE-2022-0486

Improper file permissions in the CommandPost, Collector, Sensor, and Sandbox components of Fidelis Network and Deception enables an attacker with local, administrative access to the CLI to modify affected files and enable escalation of privileges equivalent to the root user. The vulnerability is present in Fidelis Network and Deception versions prior to 9.4.5. Patches and updates are available to address this vulnerability.

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.
