CVE-2024-23652 PoC — BuildKit possible host system access from mount stub cleaner

Associated Vulnerability
Title:BuildKit possible host system access from mount stub cleaner (CVE-2024-23652)
Description: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.

Remarks
    1. It is advised to access via the original source first.
    2. Local POC snapshots are reserved for subscribers — if the original source is unavailable, the local mirror is part of the paid plan.
    3. Mirroring, verifying, and maintaining this POC archive takes ongoing effort, so local snapshots are a paid feature. Your subscription keeps the archive online — thank you for the support. View subscription plans →
