These enterprise apps aren't vetted by Apple, so they could very well be using unsafe APIs Apple doesn't recommend and would block during an App Store review process. And there are tons of ways to crash machines from userspace. Also, it's likely the iPads are running an old version of iOS. And for all we know, the iPads are jailbroken and all bets are off. Finally, it sounds like AA's software provider was able to deliver a patch, so I don't think it's just a matter of iOS being "unauditable". What OS would they be using that met your auditability standards? Even Android is not totally open.
