Description
The "nosuid" mount option causes the system to not execute "setuid" and "setgid" files with owner privileges. This option must be used for mounting any file system not containing approved "setuid" and "setguid" files.
Executing files from untrusted file systems increases the opportunity for nonprivileged users to attain unauthorized administrative access.
ℹ️ Check
Verify "/var/log/audit" is mounted with the "nosuid" option:
$ mount | grep /var/log/audit
/dev/mapper/luks-29b74747-2f82-4472-82f5-0b5eb763effc on /var/log/audit type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)
If the "/var/log/audit" file system is mounted without the "nosuid" option, this is a finding.
✔️ Fix
Modify "/etc/fstab" to use the "nosuid" option on the "/var/log/audit" directory.
