CVE-2020-1054 LPE for Windows 7x64
Install Rust if you need it https://www.rust-lang.org/learn/get-started
Compile the code:
cargo build --release
Copy the .exe from target/release/ to target and execute.
If a specific Windows KB is not installed slight changes to the exploit are required. These are noted in two places via comments. I will update what the specific KB is shortly.
