Having worked in a few large shops, I suspect what you are describing
is an internal application (firewalled off), therefore the concern by
management about getting cracked is minimal.

If this is a serious application, as opposed to lets say an internal
app that collects suggestions for the departments next picnic location,
then you should perhaps push your point. Before doing so, make sure you
can articulate how this can be a problem (which is one reason you
are here now, a good start)...what are the ramifications of
having bad data? i.e. Can someone give themselves a raise?, modify
their vacation days? put their daily pizza order on the company card?
obtain a staple and paperclip supply above and beyond the maximum allowed?
If the risk is trivial, and management isn't interested in hearing about
good coding practice, then back off and treat this as a learning experience.
If you have a traditional Dev/test/prod type environment, then your risk
of demonstrating the flaw is greatly diminished. Since you admit being
new to Perl (as well as the company) I would suggest garnering some
support from those more experienced, someone who is respected by your
management/peers (is there a "guru" around?). Another option depending on
the size of the company is to speak directly to a representative of a
IT support dept, preferrably security. Explain the scenario and ask for
advice. If they are doing their job, they will quite possibly take the
ball and just run with it (be sure that your manager knows you are seeking
their consultation, so he/she's not blindsided by a overzealous security
Appears to me like you are simply being a conscientous employee. Hopefully you
work in a place where such behavior is valued. good luck.
