This vulnerability is a 'useless' one to test against unless you are either
going to 'exploit' OPIE to confirm it is installed or have local access to
the system to check. For the systems which show up like this you will need
to see if OPIE has been installed on the systems. OPIE is not shipped with
CentOS as far as I know but it could be installed aftermarket.
if it was done with rpms'
rpm -qa | grep -i opie
otherwise you will need to look in /etc/pam.d
grep -i open /etc/pam.d/*
If it is installed, then this isn't a CentOS issue as OPIE is not shipped
but would be whoever added this to the systems problem.
