Check: GEN001140

VMware ESX 3 Server: GEN001140 (in version v1 r2)

Title

System files and directories must not have uneven access permissions. (Cat II impact)

Discussion

Discretionary access control is undermined if users, other than a file owner, have greater access permissions to system files and directories than the owner.

Check Content

Check system directories for uneven file permissions. Procedure: # ls -lL /etc /bin /usr/bin /usr/lbin /usr/ucb /sbin /usr/sbin Uneven file permissions exist if the file owner has less permissions than the group or other user classes. If any of the files in the above listed directories contain uneven file permissions, this is a finding.

Fix Text

Change the mode of files with uneven permissions so owners do not have less permission than group or world users.
