Description

This module abuses a feature of the sudo command on Progress Kemp
LoadMaster. Certain binary files are allowed to automatically elevate
with the sudo command. This is based off of the file name. Some files
have this permission are not write-protected from the default 'bal' user.
As such, if the file is overwritten with an arbitrary file, it will still
auto-elevate. This module overwrites the /bin/loadkeys file with another
executable.
