Vulnerability discussion

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

Fix text

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