I suspect using really old and shoddily cobbled together software is one of the reasons vendors usually don't like you looking under the hood. I recently figured out how to poweroff a brocade switch (there is no native command for it) and ended up enabling a hidden command that allowed me to run poweroff via bash. Bash was version 2.04, almost 20 years old! Now, it hopefully isn't used in any security-sensitive contexts to enable exploitation (or maybe it's a custom patched version), but it is sort of indicative of how these things get built.
