$10 check cgi perl program for security purposes. I need to check my cgi perl program for security holes. The program takes info from a form, does some error checking, and if everything is OK, writes that info to a text file. Along with checking for security holes, the person who checks the program will need to write a function that takes a string $str and removes invalid characters from it, or else (in the case of an email address) simply warns them that the email address is invalid. Total number of lines, including massive amounts of empty space: 272. I will provide the cgi and html files to check if necessary. Post only if you have tons of posts with DP, and you know a lot about perl/cgi security. Post some credentials please.
