Check: GEN005880

SUSE Linux Enterprise Server v11 for System z STIG: GEN005880 (in versions v1 r12 through v1 r9)

The Network File System (NFS) server must not allow remote root access. (Cat II impact)

If the NFS server allows root access to local file systems from remote hosts, this access could be used to compromise the system.

List the exports. # cat /etc/exports If any export contains "no_root_squash" or does not contain "root_squash" or "all_squash", this is a finding.

Edit the "/etc/exports" file and add "root_squash" (or "all_squash") and remove "no_root_squash".
