During a security engagement, you discover a locked interface with limited commands that blocks typical scripts. Which method would best lead to an interactive interface that bypasses these limitations?
Modify the system’s environment variables to call a different program
Create an account in the system config files via a text editor
Generate network packets to make the service crash and restart
Upload a firmware patch to alter the restricted interface
Modifying environment variables points the system to an alternate program rather than the restricted one, which allows interactive operations. The other options either involve system modifications that require higher privileges or rely on tactics that are not guaranteed to result in an interactive interface.
