CVE-2024-23652

EIP tracks 1 public exploit for CVE-2024-23652. PoCs published by abian2.

AI-analyzed exploit summary This Dockerfile exploits CVE-2024-23652 by leveraging a symlink attack during the build process to manipulate the filesystem structure. The exploit uses a tmpfs mount and symbolic link to achieve privilege escalation or container escape.

BuildKit is a toolkit for converting source code to build artifacts in an efficient, expressive and repeatable manner. A malicious BuildKit frontend or Dockerfile using RUN --mount could trick the feature that removes empty files created for the mountpoints into removing a file outside the container, from the host system. The issue has been fixed in v0.12.5. Workarounds include avoiding using BuildKit frontends from an untrusted source or building an untrusted Dockerfile containing RUN --mount feature.
