Two things: first, your untaint function isn't untainting the data. Removing parts from a tainted string doesn't make it untainted. Match (in parens) what you allow, and use that ($1) - that will be untainted. See the perlsec manual page.

But looking at the rest of the program, I don't think you are doing anything that isn't insecure.
