Check: GEN006290

HP-UX 11.31 STIG: GEN006290 (in versions v1 r19 through v1 r13)

Title

The /etc/news/hosts.nntp.nolimit file must not have an extended ACL. (Cat II impact)

Discussion

File system extended ACLs provide access to files beyond what is allowed by the mode numbers of the files. Excessive permissions on the hosts.nntp.nolimit file may allow unauthorized modification which could lead to Denial of Service to authorized users or provide access to unauthorized users.

Check Content

Check the permissions of the file. # find / -type f -name hosts.nntp.nolimit | xargs -n1 ls -lL If the permissions include a "+" the file has an extended ACL, this is a finding.

Fix Text

Remove the optional ACL from the file. # chacl -z <path>/hosts.nntp.nolimit
