More information regarding restricted shell can be found at: OneFS Restricted Shell | Dell Technologies Info Hub
CVE-2023-32492 This workaround is only applicable to a non-compliance mode cluster.
Please manually change the ownership and permissions of /ifs/netlog directory to more secure values as follows:
chmod -R 750 /ifs/netlog
chmod 770 /ifs/netlog/bundled
chmod 440 /ifs/netlog/bundled/*.bz2
chown -R root:wheel /ifs/netlog

In addition to upgrading your version of OneFS or downloading and installing the latest RUP, please manually change the permission of files using following command:
chmod 440 /ifs/netlog/bundled/*.bz2
CVE-2023-32494 This vulnerability only applies when customers are given ISI_PRIV_LOGIN_SSH or ISI_PRIV_LOGIN_CONSOLE to users.
