受影响的文件路径为：/include/common.inc.php
我们打开文件，大概在第101行，源代码如下：
foreach(Array('_GET','_POST','_COOKIE') as $_request)
{
foreach($$_request as $_k => $_v)
{
if($_k == 'nvarname') ${$_k} = $_v;
else ${$_k} = _RunMagicQuotes($_v);
}
}
或者源代码为：
foreach(Array('_GET','_POST','_COOKIE') as $_request)
{
foreach($$_request as $_k => $_v) ${$_k} = _RunMagicQuotes($_v);
}
将代码修改为：
foreach(Array('_GET','_POST','_COOKIE') as $_request)
{
foreach($$_request as $_k => $_v) {
if( strlen($_k)>0 && eregi('^(cfg_|GLOBALS)',$_k) ){
exit('Request var not allow!');
}
${$_k} = _RunMagicQuotes($_v);
}
}
保存上传即可。
