( #3333=superdoc: print w/replies, xml ) Need Help??
I would like to thank you for all the help.
I have tryed to implement the security stuff you guys talked about, some of it I could not get to work or find the documentation, So here is my new script! Any major holes in this one?
#!/usr/bin/perl -Tw #warnings and taint mode now enabled use CGI; use strict; $CGI::POST_MAX=1024 * 500; # max 500k post $CGI::DISABLE_UPLOADS = 1; # No uploads print "Content-type:text/html\n\n"; my $temp; $temp = "$ENV{'QUERY_STRING'}"; $temp =~ tr/\/A-Za-z0-9_.-//dc; $temp =~ s/\.+\///g; if( $temp =~ m#(^.+\.{1}?\w+)# ) { $temp= "../www$1"; } else { dienice "Invalid template file name..."; } #you may now use the CGI methods. my ($query) = new CGI; my (@values, $key, $i, @fary); foreach $key ($query->param) { $i = $query->param($key); if ($key =~ /required/i) {if ( ($i eq "") && ($i == "") ) {failure();} +} } open(INF, "< $temp") or dienice("Cant open $temp"); seek(INF,0,0); @fary = <INF>; close (INF); foreach $key ($query->param) { @values = $query->param($key); foreach $i (@fary) {$i =~ s/\[$key\]/@values/g;} } my $mailprog = '/usr/lib/sendmail'; open (MAIL, "|$mailprog -t") or dienice("Can't access $mailprog!\n"); foreach $i (@fary) { print MAIL "$i"; } close (MAIL); my $url = $query->param('success'); print "<Meta HTTP-EQUIV=\"Refresh\" CONTENT=\"0;URL=$url\">\n\n"; print "<a href=\"$url\">If you are not forwarded in 5 seconds, please +click here.<\/a>"; exit; sub failure { my $url = $query->param('failure'); print "<Meta HTTP-EQUIV=\"Refresh\" CONTENT=\"0;URL=$url\">\n\n"; print "<a href=\"$url\">If you are not forwarded in 5 seconds, please +click here.<\/a>"; exit; } sub dienice { my($errmsg) = @_; my($webmaster) = 'webmaster@mydomain.com'; print <<Eof; <html><head><title>Error!!</title></head><body>The error was $errmsg</ +body></html> Eof exit; }

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
