Quick assessment

Affected
Report One MyReport Updater
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

MyReport Updater 至版本 2.1.1 存在一个本地权限提升漏洞，允许低权限用户利用 SYSTEM updater 服务将攻击者提供的存档文件安装到任意目录中。攻击者可以通过 gRPC 调用 UpdaterManager.exe，设置恶意的引用服务器（reference server）和安装位置（installLocation），从而植入一个如 HID.dll 这样的动态链接库文件。该 DLL 会被 osk.exe（屏幕键盘程序）加载，进而使攻击者获得 SYSTEM 级别的系统权限。
