Title

Automated file system mounting tools must not be enabled unless needed. (Cat III impact)

Discussion

Automated file system mounting tools may provide unprivileged users with the ability to access local media and network shares. If this access is not necessary for the system’s operation, it must be disabled to reduce the risk of unauthorized access to these resources.

Check Content

Check /etc/rc.config.d/nfsconf for the AUTOFS automount setting. # cat /etc/rc.config.d/nfsconf | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' | grep -v "^#" | \ grep -i "AUTOFS=1" If set to 1, this is a finding. After testing, if the autofs service is required, this vulnerability is not applicable.

Fix Text

Stop and disable the autofs service. Edit /etc/rc.config.d/nfsconf and set the AUTOFS setting to 0. Restart the nfs.client service. # /usr/sbin/init.d/nfs.client stop # /usr/sbin/init.d/nfs.client start
