| 描述 | 1. Vulnerability Introduction
github地址:https://github.com/weng-xianhu/eyoucms/issues/68
-System Name: EyouCMS
-System version: v1.7.1
-Vulnerability triggers routing:/index. php? s=/home/Ask/ajax_show_comment
-Control parameter: click_ike
-Harm: SQL injection, attackers can extract sensitive information such as administrator account passwords from the database by passing in malicious SQL statements
2. Vulnerability Analysis
Vulnerable File (Model layer): application/home/model/Ask.php
The GetAskReplyData method accepts the $param['click_like'] parameter, only checks whether the parameter is empty, and if not empty, directly concatenates it into the ORDER BY clause, then calls ->order() to execute the raw SQL:
$OrderBy = !empty($param['click_like'])
? 'a.click_like ' . $param['click_like'] . ', a.add_time asc'
: 'a.add_time asc';
->order($OrderBy)
Vulnerable Trigger File (Controller layer): application/home/controller/Ask.php
In the ajax_show_comment method, the route /home/Ask/ajax_show_comment accepts all parameters via input('param.') and directly passes them into the GetAskReplyData method without any filtering or validation, resulting in SQL injection:
public function ajax_show_comment()
{
if (IS_AJAX_POST) {
$param = input('param.'); // No filtering
$Comment = $this->AskModel->GetAskReplyData($param, $this->parent_id);
}
}
