A security researcher has publicly disclosed an exploit for a new Windows zero-day local privilege elevation vulnerability that gives admin privileges in Windows 10, Windows 11, and Windows Server.
The vulnerability affects all supported versions of Windows, including Windows 10, Windows 11, and Windows Server 2022.
Yesterday, Naceri published a working proof-of-concept exploit for the new zero-day on GitHub, explaining that it works on all supported versions of Windows.
00 bounty award under the Windows Insider Preview Bounty Program.
As is typical with zero days, Microsoft will likely fix the vulnerability in a future Patch Tuesday update.
"Any attempt to patch the binary directly will break windows installer. So you better wait and see how Microsoft will screw the patch again."
