Vulnerability discussion

The .rhosts, .shosts, hosts.equiv, and shosts.equiv files are used to configure host-based authentication for individual users or the system. Host-based authentication is not sufficient for preventing unauthorized access to the system.

Check content

Check for the existence of the files. The .rhosts and .shosts files are stored in home directories. (If a user does not have a home directory assigned in /etc/passwd, the root directory (/) is assigned as a default home directory.) Procedure (the first command is five lines long): # for homedir in `cut -d: -f6 /etc/passwd | awk '$1 == "" {$1 = "/"} {print $1}'`; do ls -l $homedir/.rhosts; ls -l $homedir/.shosts; done # ls -l /etc/hosts.equiv # ls -l /etc/ssh/shosts.equiv If .rhosts, .shosts, hosts.equiv, or shosts.equiv are found, this is a finding.

Fix text

Remove the .rhosts, .shosts, hosts.equiv, and/or shosts.equiv files.

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.
