Information

AlmaLinux OS 9 must mount /var/log with the nosuid option.

GROUP ID: V-269325
RULE ID: SV-269325r1050207

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.

Solution

Modify "/etc/fstab" to use the "nosuid" option on the "/var/log" directory.
