Vulnerability Type: LPE Affected Versions: • Windows Server up to 2022 • Windows XP through 11 Privileges Gained: From Administrator to SYSTEM Price: $150K

In the post, the author is offering an LPE exploit for Windows for sale. According to the author, the exploit works on a very wide range of Windows versions: from XP to Windows 11, as well as on server editions up to Server 2022.

The author specifically emphasizes that the exploit allegedly does not require any third-party software, drivers, or user interaction. He claims that the code can execute directly in memory and trigger almost instantly.

In addition to the main privilege escalation, the seller offers an additional PoC for escalating privileges from Administrator to SYSTEM. To do this, he says, a token impersonation mechanism is used—obtaining a more privileged access token from a system process or service.

As a demonstration, the author provides links to videos showing the exploit being run on operating systems with various antivirus programs. In the videos, he demonstrates launching a command prompt and checking the current user and their privileges. Two implementations are mentioned: a PowerShell variant with a .NET payload and a separate .exe executable without obfuscation or encryption.

On one sample, 5 out of 16 engines triggered an alert; on another, 4 out of 16. The author notes that some security solutions flag the file as suspicious or malicious, but asserts that some of them only react during static scanning and do not necessarily prevent exploitation at runtime.
