SV-91835r1_rule There must be no shosts.equiv files on the SUSE operating system.

Vulnerability discussion

The shosts.equiv files are used to configure host-based authentication for the system via SSH. Host-based authentication is not sufficient for preventing unauthorized access to the system, as it does not require interactive identification and authentication of a connection request, or for the use of two-factor authentication.

Check content

Verify there are no "shosts.equiv" files on the SUSE operating system. Check the system for the existence of these files with the following command: # ls -al /etc/ssh/shosts.equiv If any "shosts.equiv" files are found on the system, this is a finding.

Fix text

Remove any ".shosts.equiv" files found on the SUSE operating system. # rm /etc/ssh/shosts.equiv

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.
