Thank you for your response. I am asking because I have several millions lines of legacy perl code in cgi-bin, and I have to make sure there are no vulnerabilities.

The code seems to do what it's supposed to, so functionality is not an issue.

I need to know if there are any security concerns about readParse, because that would mean I need to locate all the occurences of readParse and replace them with something more secure.

If readParse statements do not create vulnerabilities in the code, then I can leave them alone.
