RHEL 8 STIG:
RHEL-08-010610
(in versions v1 r14 through v1 r1)
Title
RHEL 8 must prevent code from being executed on file systems that are used with removable media. (Cat II impact)
Discussion
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 files, as they may be incompatible. Executing files from untrusted file systems increases the opportunity for unprivileged users to attain unauthorized administrative access.
Check Content
Verify file systems that are used for removable media are mounted with the "noexec" option with the following command: $ sudo more /etc/fstab UUID=2bc871e4-e2a3-4f29-9ece-3be60c835222 /mnt/usbflash vfat noauto,owner,ro,nosuid,nodev,noexec 0 0 If a file system found in "/etc/fstab" refers to removable media and it does not have the "noexec" option set, this is a finding.
Fix Text
Configure the "/etc/fstab" to use the "noexec" option on file systems that are associated with removable media.
