Check: GEN006140

Solaris 10 SPARC STIG: GEN006140 (in versions v2 r4 through v1 r19)

Title

The smb.conf file must have mode 0644 or less permissive. (Cat II impact)

Discussion

If the smb.conf file has excessive permissions, the file may be maliciously modified and the Samba configuration could be compromised.

Check Content

Check the mode of the smb.conf 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 smb.conf has a mode more permissive than 0644, this is a finding.

Fix Text

Change the mode of the smb.conf file to 0644 or less permissive. Procedure: # chmod 0644 /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf
