AIX 6.1 SECURITY TECHNICAL IMPLEMENTATION GUIDE: GEN006210 (in versions v1 r14 through v1 r10)

Title

The /var/private/smbpasswd file must not have an extended ACL. (Cat II impact)

Discussion

If the permissions of the smbpasswd file are too permissive, the smbpasswd file may be maliciously accessed or modified, potentially resulting in the compromise of Samba accounts.

Check Content

Check the group ownership of the Samba configuration file. # aclget /var/private/smbpasswd If the extended attributes are not disabled, this is a finding.

Fix Text

Remove the extended ACL from the /var/private/smbpasswd file. # acledit /var/private/smbpasswd
