熊海cms v1.0 完全代码审计

很久以前写的，写这个东西更多的是为了说明我自己的一个思路，即按照程序功能点进行代码审计，

这样经过一段时间训练，熟悉了某种功能的正确和错误实现方法，遇到类似的代码就可以很快看出是否有问题了

---

0 安装功能
0.1 检查是否存在锁文件
没问题，后面几项只有在程序未安装时进行
0.2 连接数据库，导入sql文件
0.3 将数据库连接信息写入配置文件
* 代码执行
```
$dbhost = $_POST['dbhost'];
$dbuser = $_POST['dbuser'];
$dbpwd = $_POST['dbpwd'];
$dbname = $_POST['dbname'];
...
$content = "<?php
\$DB_HOST='" . $dbhost . "';
\$DB_USER='" . $dbuser . "';
\$DB_PWD='" . $dbpwd . "';
\$DB_NAME='" . $dbname . "';
?>
";
$of = fopen('../inc/conn.info.php', 'w');
if ($of) {
fwrite($of, $content);
}
echo "MySQL数据库连接配置成功!<br /><br />";
```
0.4 加入管理员
* sql 注入
```
$user = $_POST['user'];
$password = md5($_POST['password']);
...
$query = "UPDATE manage SET user='$user',password='$password',name='$user'";
@mysql_query($query) or die('修改错误：' . mysql_error());
```

1 默认访问首页
* 文件包含
```
$file = addslashes($_GET['r']); //接收文件名
$action = $file == '' ? 'index' : $file; //判断为空或者等于index
include 'files/' . $action . '.php'; //载入相应文件
```
