SV-40298r2_rule The smb.conf file must use the hosts option to restrict access to Samba.

Vulnerability discussion

Samba increases the attack surface of the system and must be restricted to communicate only with systems requiring access.

Check content

Examine 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: # more /etc/smb.conf /etc/sfw/smb.conf /etc/samba/smb.conf /etc/sfw/samba/smb.conf If the hosts option is not present to restrict access to a list of authorized hosts and networks, this is a finding.

Fix text

Edit the smb.conf file and set the hosts option to permit only authorized hosts to access Samba.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
