Title

The limitpriv zone option must be set to the vendor default or less permissive. (Cat III impact)

Discussion

Solaris zones can be assigned privileges generally reserved for the global zone using the "limitpriv" zone option. Any privilege assignments in excess of the vendor defaults may provide the ability for a non-global zone to compromise the global zone.

Check Content

This check applies to the global zone only. Determine the zone that you are currently securing. # zonename If the command output is "global", this check applies. List the non-global zones on the system. # zoneadm list -vi | grep -v global From the output list of non-global zones found, determine if any are Kernel zones. # zoneadm list -cv | grep [zonename] | grep solaris-kz Exclude any Kernel zones found from the list of local zones. List the configuration for each zone. # zonecfg -z [zonename] info |grep limitpriv If the output of this command has a setting for limitpriv and it is not: limitpriv: default this is a finding.
