SV-12488r2_rule The .rhosts, .shosts, hosts.equiv, shosts.equiv, /etc/passwd, /etc/shadow, and/or /etc/group files must not contain a plus (+) without defining entries for NIS+ netgroups.

Vulnerability discussion

A plus (+) in system accounts' files causes the system to lookup the specified entry using NIS. If the system is not using NIS, no such entries should exist.

Check content

Check system configuration files for plus (+) entries. Procedure: # find / -name .rhosts -exec grep + {} \; # find / -name .shosts -exec grep + {} \; # find / -name hosts.equiv -exec grep + {} \; # find / -name shosts.equiv -exec grep + {} \; # grep + /etc/passwd # grep + /etc/shadow # grep + /etc/group If the .rhosts, .shosts, hosts.equiv, shosts.equiv, /etc/passwd, /etc/shadow, and/or /etc/group files contain a plus (+) and do not define entries for NIS+ netgroups, this is a finding.

Fix text

Edit the .rhosts, .shosts, hosts.equiv, shosts.equiv, /etc/passwd, /etc/shadow, and/or /etc/group files and remove entries containing a plus (+).

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.
