OL 8 file systems must not execute binary files that are imported via Network File System (NFS).


Finding ID Version Rule ID IA Controls Severity

The "noexec" mount option causes the system not to execute binary files. This option must be used for mounting any file system not containing approved binary as they may be incompatible. Executing files from untrusted file systems increases the opportunity for unprivileged users to attain unauthorized administrative access.

Check Text ( C-52058r779436_chk )
Verify that file systems being imported via NFS are mounted with the "noexec" option with the following command:

$ sudo grep nfs /etc/fstab | grep noexec

UUID=e06097bb-cfcd-437b-9e4d-a691f5662a7d /store nfs rw,nosuid,nodev,noexec 0 0

If a file system found in "/etc/fstab" refers to NFS and it does not have the "noexec" option set, this is a finding.
Fix Text (F-52012r779437_fix)
Configure the "/etc/fstab" to use the "noexec" option on file systems that are being imported via NFS.
