TMA-AIX-4.3.4.7
Ensure exec daemon is not in use
Description
The recommendation is that rexecd is disabled. This service can be performed securely using OpenSSH. This entry starts the rexecd daemon when required. This daemon executes a command from a remote system once the connection has been authenticated. The exec service is used to execute a command sent from a remote server. The username and passwords are passed over the network in clear text and therefore insecurely. Unless required the rexecd daemon will be disabled. Audit: `lssrc -s inetd -l` must not list the service (count 0).
How it is checked
Audit method: Shell command
command -v lssrc >/dev/null 2>&1 || exit 1; n=$(lssrc -s inetd -l 2>/dev/null | grep -c 'exec'); echo "$n"- Expected output
0
How it is fixed
Fix method: Guidance or infrastructure patch
In /etc/inetd.conf, comment out the exec entry: chsubserver -r inetd -C /etc/inetd.conf -d -v 'exec' -p 'tcp6' refresh -s inetd
