漏洞描述

SHAREit application for Android是中国众联极享科技（SHAREit）公司的一款基于Android平台的内容分发应用程序。该程序主要用于设备之间的文件传输。 基于Android平台的SHAREit应用4.0.36之前版本中存在授权问题漏洞，该漏洞源于网络系统或产品中缺少身份验证措施或身份验证强度不足。

The SHAREit application before 4.0.36 for Android allows a remote attacker (on the same network or joining public "open" Wi-Fi hotspots created by the application when file transfer is initiated) to bypass authentication by trying to fetch a non-existing page. When the non-existing page is requested, the application responds with a 200 status code and empty page, and adds the requesting client device into the list of recognized devices.
