Discuz! 4.x Variable Override Vulnerabilit

Code

                                                该漏洞存在于Discuz!4.x很多年了,在fix号:20080804里[1]补丁那个wap宽字节漏洞时被一起偷偷补丁了,补丁代码:

$chs = '';
if($_POST && $charset != 'utf-8') {
	$chs = new Chinese('UTF-8', $charset);
	foreach($_POST as $key => $value) {
		$$key = addslashes(stripslashes($chs->Convert($$key)));
	}
	unset($chs);
}
