CVE-2020-7824

A vulnerability in the web-based management interface of iPECS could allow an authenticated, remote attacker to get administrator permission. The vulnerability is due to insecure permission when handling session cookies. An attacker could exploit this vulnerability by modification the cookie value to an affected device. A successful exploit could allow the attacker access to sensitive device information, which includes configuration files.

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.
