CVE-2019-1162: Windows ALPC Elevation of Privilege Vulnerability
An elevation of privilege vulnerability exists when Windows improperly handles calls to Advanced Local Procedure Call (ALPC). An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. To exploit this 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 and take control over an affected system. The update addresses the vulnerability by correcting how Windows handles calls to ALPC.

Frequently Asked Questions
Who is exposed to exploitation?
Systems running the listed Microsoft Windows products are exposed if they are affected and unpatched. Exploitation is local: the attacker must first be able to log on to the target system.
What access does an attacker need to exploit this issue?
An attacker needs a local authenticated logon and must run a specially crafted application. No user interaction is required after the attacker can execute that application.
What is the impact of successful exploitation?
Successful exploitation allows arbitrary code execution in the Local System security context. This can enable installing programs, viewing, changing, or deleting data, and creating accounts with full user rights.
What should be done to remediate the vulnerability?
Apply the available security update. The update corrects how Windows handles calls to Advanced Local Procedure Call (ALPC).
