SV-50395r2_rule The rshd service must not be running.

Vulnerability discussion

The rsh service uses unencrypted network communications, which means that data from the login session, including passwords and all other information transmitted during the session, can be stolen by eavesdroppers on the network.

Check content

To check that the "rsh" service is disabled in system boot configuration, run the following command: # chkconfig "rsh" --list Output should indicate the "rsh" service has either not been installed, or has been disabled, as shown in the example below: # chkconfig "rsh" --list rsh off OR error reading information on service rsh: No such file or directory If the service is running, this is a finding.

Fix text

The "rsh" service, which is available with the "rsh-server" package and runs as a service through xinetd, should be disabled. The "rsh" service can be disabled with the following command: # chkconfig rsh off

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.
