How does something like c99shell allow a local user (not root) to read the /etc/shadow file?

I do not vouch for every app that is written to break good security practices. Try $ ls -l /etc/shadow

If the tool you are using allows normal users access to /etc/shadow it is using some sort of root privileges, either it's a suid tool (ouch) or it needs entries in /etc/sudoers (visudo). In either case, I cannot think of a valid reason to allow normal users access to this file.
