SYSTEM code execution via writable Engine share

Published Jan 23, 2020 · Updated Aug 5, 2024

Remote code execution in IXP EasyInstall 6.2.13723 allows remote authenticated users to run code as SYSTEM through the Engine Service share. The server exposes IXP$ with default permissions that let those users replace directories and files, including batch scripts executed by the service. Valid share access is required; modified files execute as NT AUTHORITY\SYSTEM on the server and managed clients.
