CVE-2018-1113
4.8 · MEDIUMOverview
CVE-2018-1113 is a medium-severity vulnerability affecting redhat setup. It was published on July 3, 2018 and has a CVSS 3.0 base score of 4.8 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 4.8, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
setup before version 2.11.4-1.fc28 in Fedora and Red Hat Enterprise Linux added /sbin/nologin and /usr/sbin/nologin to /etc/shells. This violates security assumptions made by pam_shells and some daemons which allow access based on a user's shell being listed in /etc/shells. Under some circumstances, users which had their shell changed to /sbin/nologin could still access the system.
Remediation
Check the references section for vendor advisories and patches from redhat. Update setup to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
