Technical description

The SSH configuration in the Red Hat mkdumprd script for kexec-tools, as distributed in the kexec-tools 1.x before 1.102pre-154 and 2.x before 2.0.0-209 packages in Red Hat Enterprise Linux, disables the StrictHostKeyChecking option, which allows man-in-the-middle attackers to spoof kdump servers, and obtain sensitive core information, by using an arbitrary SSH key.

Remediation

Check the references section for vendor advisories and patches from redhat. Update kexec-tools 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.
