A security researcher has publicly disclosed an exploit for a Windows local privilege elevation vulnerability that allows anyone to gain admin privileges in Windows 10.
Using this vulnerability, threat actors with limited access to a compromised device can easily elevate their privileges to help spread laterally within the network, create new administrative users, or perform privileged commands. The vulnerability affects all supported support versions of Windows 10 before the January 2022 Patch Tuesday updates.

Researcher releases bypass to patched vulnerability​


As part of the January 2022 Patch Tuesday, Microsoft fixed a 'Win32k Elevation of Privilege Vulnerability' vulnerability tracked as CVE-2022-21882, which is a bypass for the previously patched and actively exploited CVE-2021-1732 bug. Microsoft attributes the discovery of this vulnerability to RyeLv, who shared a technical analysis of the vulnerability after Microsoft released the patch.

BleepingComputer also tested the vulnerability and had no problem compiling the exploit and using it to open Notepad with SYSTEM privileges on Windows 10, as shown below. BleepingComputer could not get the exploit to work on Windows 11.
Windows 11 safer than Windows 10 ?
