Description
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.
ℹ️ Check
Note: If no NFS mounts are configured, this requirement is Not Applicable.
Verify 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
Configure the "/etc/fstab" to use the "noexec" option on file systems that are being imported via NFS.
