Check Text ( C-29848r488639_chk )
Check system configuration files for plus (+) entries.

Procedure:
# find / -name .rhosts -exec grep + {} \;

# find / -name .shosts -exec grep + {} \;

# find / -name hosts.equiv -exec grep + {} \;

# find / -name shosts.equiv -exec grep + {} \;


# grep + /etc/passwd
# grep + /etc/shadow
# grep + /etc/group

If the .rhosts, .shosts, hosts.equiv, shosts.equiv, /etc/passwd, /etc/shadow, and/or /etc/group files contain a plus (+) and do not define entries for NIS+ netgroups, this is a finding.

Edit the .rhosts, .shosts, hosts.equiv, shosts.equiv, /etc/passwd, /etc/shadow, and/or /etc/group files and remove entries containing a plus (+).
