CVE-2024-9407
MediumCVSS 4.7Exploitation Probability (EPSS)
Low risk20th percentile - higher than 20% of all known CVEs
Summary
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.
Risk Assessment
An attacker can gain access to sensitive host data during the image build process, potentially leading to data leakage or modification, even in SELinux environments.
Recommendation
Update Docker to a patched version. Restrict trust in images and Dockerfiles, and monitor build processes.
