Title
Enabling SSH and Shellinabox on the vulnerable machine
Summary
E3 Site Supervisor Control (firmware version < 2.31F01) contains a hidden API call in the application services that enables SSH and Shellinabox, which exist but are disabled by default. An attacker with admin access to the application services can utilize this API to enable remote access to the underlying OS.

Mitigation
Phases: Architecture and Design, Implementation
Description:
- The implementation of chicken bits in a released product is highly discouraged. If implemented at all, ensure that they are disabled in production devices. All interfaces to a device should be documented.
CAPEC-212: Functionality Misuse
An adversary leverages a legitimate capability of an application in such a way as to achieve a negative technical impact. The system functionality is not altered or modified but used in a way that was not intended. This is often accomplished through the overuse of a specific functionality or by leveraging functionality with design flaws that enables the adversary to gain access to unauthorized, sensitive data.
CAPEC-36: Using Unpublished Interfaces or Functionality
An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.
