No. Security is hard. Security in any system is just that, systemic and it's pervasive! Hence, fixing a hard coded admin password and default OPEN WiFi network has, righlty so, scared the beejesus out of this company- prompting them to do a full security audit of the code (hopefully.)
If you can't do the "simple" security fixes, there are far, far, worse security concerns lurking underneath- or in accounting, or maybe the front door to the company has this hitch in it where it doesn't lock just right.
