    Pyramid static view path traversal up one directory

    CVE-2023-40587 · GHSA-j8g2-6fc7-q8f8

    Affected
    • PyPI pyramid >= 2.0.0, < 2.0.2
    Fixed in
    2.0.2· Vendor fix available
    Issue
    Impact This impacts users of Python 3.11 that are using a Pyramid static view with a full filesystem path and have a index.html file that is located exactly one directory above the location of the static view's file system path. No further path traversal exists, and the only file that could be disclosed accidentally is index.html. Example: And directory tree: Patches Pyramid now will reject any path that contains a null-byte out of caution. While valid in directory/file names, we would strongly consider it a mistake to use null-bytes in naming files/directories. Secondly, Python 3.11, and 3.12 has fixed the underlying issue in os.path.normpath to no longer truncate on the first 0x00 found, returning the behavior to pre-3.11 Python, un an as of yet unreleased version, see: - https://github.com/python/cpython/issues/106242 - https://github.com/python/cpython/pull/106816 At the time the following Python versions are not fixed: - Python 3.11.0 to 3.11.4 - Python 3.12.0a1 to 3.12.0rc1…

    Recommended action: Upgrade to 2.0.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
