Vulnerability discussion

Having the "+" character in the hosts.lpd (or equivalent) file allows all hosts to use local system print resources.

Check content

Solaris uses the "IPP" print service and can also use the Samba print service. Verify remote host access is limited. Procedure: # grep -i Listen /etc/apache/httpd-standalone-ipp.conf The /etc/apache/httpd-standalone-ipp.conf file must not contain a Listen *: or equivalent line. If the network address of the "Listen" line is unrestricted, this is a finding. # grep -i "Allow From" /etc/apache/httpd-standalone-ipp.conf The "Allow From" line within the "" element should limit access to the printers to @LOCAL and specific hosts. If the "Allow From" line contains "All", this is a finding. Verify guest access to printers shared via Samba is restricted according to GEN006235.

Fix text

Configure IPP to use only the localhost or specified remote hosts. Procedure: Modify the /etc/apache/httpd-standalone-ipp.conf file to "Listen" only to the local machine or a known set of hosts (i.e., Listen localhost:631). Modify the /etc/apache/httpd-standalone-ipp.conf file "" element to "Deny From All" and "Allow from 127.0.0.1" or allowed host addresses. Restart the IPP service: # svcadm restart ipp-listener

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.
