HTTP: Microsoft Windows Win32k Kernel Driver CVE-2020-16907 Privilege Escalation

This signature detects attempts to exploit a known vulnerability against Microsoft Windows Win32k Kernel Driver. A successful attack can lead to elevation of privilege and arbitrary code execution.

Extended Description

An elevation of privilege vulnerability exists in Windows when the Windows kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. 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 of an affected system. The update addresses this vulnerability by correcting how the Windows kernel-mode driver handles objects in memory.
