Discussion

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.

Check Content

Verify "/var/log" is mounted with the "nosuid" option:

$ mount | grep '/var/log '

/dev/mapper/luks-e0d162f5-fad8-463e-8e39-6bd09e672961 on /var/log type xfs (rw,nosuid,nodev,noexec,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota)

If the "/var/log" file system is mounted without the "nosuid" option, this is a finding.
