Description

MyReport Updater through 2.1.1 contains a local privilege escalation vulnerability that allows low-privileged users to make the SYSTEM updater service install attacker-supplied archives into arbitrary directories. Attackers can use UpdaterManager.exe over gRPC to set a malicious reference server and installLocation, planting a DLL like HID.dll loaded by osk.exe to gain SYSTEM privileges.
