Re: [vox-tech] Need help securing a simple perl CGI

Hash: SHA1

I have re-writen this script so that it does not take in the file name directly, but instead reads in a number and gets the file name from an external config file.

I still need to figure out how to get it to work with non-html mime types.


# Perl CGI script to decompress gzip'd html files on-the-fly to
# save disk space on the server. This will likely slow things
# a bit...

# Edit line 13 to if needed. files.lst should contain one file name per line, with
# path relitive to $filepath. The first entry is called with 'decomp.pl?filenum=0',
# the second with 'decomp.pl?filenum=1', etc. First entry shoul be an error page.

use CGI::Carp qw(fatalsToBrowser);                      # Tell user if we crap out.

my $filepath = "/var/home/ryan/WWW/";                   # Set to your web directory

my $request;

if ($ENV{'REQUEST_METHOD'} eq "GET") {                  # Was this 'GET' request?
        $request = $ENV{'QUERY_STRING'};                # Store query string
        $request =~ s/\+/ /g;                           # undo encoding
        $request =~ s/%(..)/pack("c",hex($1))/ge;       # ditto
} else {
        $request = ;                            # Handle a POST request

open(FILES, 'files.lst')                                # open the file list
        or die "Can't open files.lst: $!";              # whine and die if fail

my %data = split (/=/, $request);                       # Turn the request into a hash
my @filelist = ;                                        # Put file list into array
my $pagenum = $data{'page'};                            # What file num does user want?
my $filename = $filelist[$pagenum];                     # Get the needed entry
my $filename = "$filepath"."$filename";                 # Merge root path into file name
                                                        # There ought to be error handling here

print "Content-Type: text/html\n\n";                    # Tell browser to render html
print `zcat $filename`;                                 # Decompress and output the file
