If SLEM 5 were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. This requirement applies to SLEM 5 with software libraries that are accessible and configurable, as in the case of interpreted languages. Software libraries also include privileged programs which execute with escalated privileges. Only qualified and authorized individuals must be allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications.
Verify that the system commands have mode "755" or less permissive with the following command:
> find -L /usr/local/bin /usr/local/sbin -perm /022 -type f -exec stat -c "%n %a" '{}' \;
If any files are found to be group-writable or world-writable, this is a finding.Configure the system commands to be protected from unauthorized access.
If the command requiring a permissions change resides in /usr/local/bin or /usr/local/sbin run the following command:
> sudo find -L /usr/local/bin /usr/local/sbin -perm /022 -type f -exec chmod 755 '{}' \;
If the command requiring a permissions change resides in /bin, /sbin, /usr/bin, /or usr/sbin run the following commands:
> sudo transactional-update shell
> sudo find -L /bin /sbin /usr/bin /usr/sbin -perm /022 -type f -exec chmod 755 '{}' \;
> exit
> sudo reboot
