CVE-2024-9407 Buildah: podman: improper input validation in bind-propagation option of dockerfile run --mount instruction

What is CVE-2024-9407?

CVE-2024-9407 is a medium-severity path traversal vulnerability in Red Hat Enterprise Linux 10, published on 1 Oct 2024. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

A vulnerability exists in the bind-propagation option of the Dockerfile RUN --mount instruction. The system does not properly validate the input passed to this option, allowing users to pass arbitrary parameters to the mount instruction. This issue can be exploited to mount sensitive directories from the host into a container during the build process and, in some cases, modify the contents of those mounted files. Even if SELinux is used, this vulnerability can bypass its protection by allowing the source directory to be relabeled to give the container access to host files.

Weakness: CWE-20
