From what I can see... ditch this script.

  • It is for a "PERL 5-enabled web site". What ever that is :)
  • It uses cgi-lib, this is terrible. It is perl 4 code and has not been supported for 4 to 5 years
  • They are making you pay for it (not that I am against that, but that is usually a red-flag to me that these guy/girls do not know what they are doing, especially since the functionality is trivial).
  • The functionality they offer is minimal.
  • and the topper is they require permissions at 777. (if you had this on my server I would shut down your account)

    Run, don't walk away from this script.

    UPDATE: this is basically parsing routine 
    my $cache = 'blah=hi;cat /etc/passwd';

@pairs = split(/&/, $cache);
foreach $pair (@pairs) {
    ($name, $value) = split(/=/, $pair);

    $value =~ tr/+/ /;
    $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;


    if (defined($FORM{$name})){
        $FORM{$name}.="\0";
    }

    $FORM{$name} .= &strip($value);

}

sub strip {

     my($cheese)= @_;
       $cheese =~ s/\t/ /g; 
     $cheese =~ s/\|//g; 
     $cheese =~ s/\r//g;   # should use this.
     $cheese =~ s/\n/<P>/g;   # should use this.
     $cheese =~ s/%95/<li>/g;
     $cheese =~ s/"<P><P>"/<P>/g; 
      return ($cheese);
}

    Pardon me if I'm wrong but this does not strip out ;'s which gets really bad since I just spotted. 
     $directory_size = `du -s $target/$where `;
