Check: GEN002060
AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE:
GEN002060
(in versions v1 r14 through v1 r10)
Title
All .rhosts, .shosts, .netrc, or hosts.equiv files must be accessible by only root or the owner. (Cat II impact)
Discussion
If these files are accessible by users other than root or the owner, they could be used by a malicious user to set up a system compromise.
Check Content
# find / -type f -name .rhosts # ls -alL /<directorylocation>/.rhosts # find / -type f -name .shosts # ls -alL /<directorylocation>/.shosts # find / -type f -name hosts.equiv # ls -lL /<directorylocation>/hosts.equiv # find / -type f -name shosts.equiv # ls -lL /<directorylocation>/shosts.equiv If the .rhosts, .shosts, hosts.equiv, or shosts.equiv files have permissions greater than 700, this is a finding.
Fix Text
Ensure the permission for these files is set at 700 or less and the owner is the owner of the home directory that it is in. These files, outside of home directories (other than hosts.equiv which is in /etc and owned by root), have no meaning.
