Pretty much none. At least from CPAN, specifically. :) opendir and readdir (or File::Find if you need to look down a directory tree), Digest::MD5, CGI, and File::Copy are core modules which ship with Perl.

DBI and the appropriate DBD::Foo driver for your database would need to be installed from CPAN.
