CVE-2017-0298 →

📋 Description

An elevation of privilege exists in Windows when a DCOM object in Helppane.exe, configured to run as the interactive user, fails to properly authenticate the client. An attacker who successfully exploited the vulnerability could run arbitrary code in another user's session. To exploit the vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability after another user logged on to the same system via Terminal Services or Fast User Switching. The update addresses the vulnerability by correcting how Helppane.exe authenticates the client.
