Official description

An issue was discovered in za-internet C-MOR Video Surveillance 5.2401. Due to improper or missing access control, low privileged users can use administrative functions of the C-MOR web interface. It was found out that different functions are only available to administrative users. However, access those functions is restricted via the web application user interface and not checked on the server side. Thus, by sending corresponding HTTP requests to the web server of the C-MOR web interface, low privileged users can also use administrative functionality, for instance downloading backup files or changing configuration settings.

The underlying weakness: Improper Access Control

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

How developers prevent this class of flaw

  • Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
  • 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.
