# SCO Openserver 5.0.7 enable exploit
# ===================================
# A standard stack-overflow exists in the handling of
# command line arguements in the 'enable' binary. A user
# must be configured with the correct permissions to
# use the "enable" binary. SCO user documentation suggests
# "You can use the asroot(ADM) command. In order to grant a
# user the right to enable and disable tty devices". This
# exploit assumes you have those permissions.
#
# Example.
#
# $ id
# uid=200(user) gid=50(group) groups=50(group)
# $ perl enablex.pl
# # id
# uid=0(root) gid=50(group) egid=18(lp) groups=50(group)
