Discussion

The "noexec" mount option causes the system to not 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 nonprivileged users to attain unauthorized administrative access.

Verify AlmaLinux OS 9 has the "noexec" option configured for all NFS mounts with the following command:

$ grep nfs /etc/fstab 

192.168.1.9:/mnt/export /backups nfs4 rw,nosuid,nodev,noexec,sync,soft,sec=krb5p:krb5i:krb5

If the system is mounting file systems via NFS and the "noexec" option is missing, this is a finding.
