A vulnerability classified as critical was found in MindsDB. Affected by this vulnerability is the function shutil.unpack_archive of the component Tarball Handler. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

MindsDB is an open source machine learning platform. An unsafe extraction is being performed using `shutil.unpack_archive()` from a remotely retrieved tarball. Which may lead to the writing of the extracted files to an unintended location. This vulnerability is sometimes called a **TarSlip** or a **ZipSlip variant**. Unpacking files using the high-level function `shutil.unpack_archive()` from a potentially malicious tarball without validating that the destination file path remained within the intended destination directory may cause files to be overwritten outside the destination directory. An attacker could craft a malicious tarball with a filename path, such as `../../../../../../../../etc/passwd`, and then serve the archive remotely using a personal bucket `s3`, thus, retrieve the tarball through **mindsdb** and overwrite the system files of the hosting server. This issue has been addressed in version 22.11.4.3. Users are advised to upgrade. Users unable to upgrade should avoid ingesting archives from untrusted sources.

The weakness was released 03/31/2023 as GHSA-7x45-phmr-9wqp. The advisory is shared at github.com. This vulnerability is known as CVE-2022-23522 since 01/19/2022. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1006 for this issue.
