Title

The /etc/smb.conf file must not have an extended ACL. (Cat II impact)

Discussion

Excessive permissions could endanger the security of the Samba configuration file and, ultimately, the system and network.

Check Content

Check the group ownership of the Samba configuration file. Default locations for this file include /etc, /etc/sfw, /etc/samba, and /etc/sfw/samba. If the system has Samba installed in non-standard locations, also check the smb.conf in those locations. Procedure: # ls -lL /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf If the permissions include a "+", the file has an extended ACL and this is a finding.

Fix Text

Remove the extended ACL from the file: # getfacl /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf Remove each ACE returned: # setfacl -d [ACE] /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf
