CVE-2022-23531: GuardDog vulnerable to arbitrary file write when scanning a specially-crafted PyPI package

CVE-2022-23531 · Severity: low · CVSS 3.1 · Published 2022-12-17

GuardDog is a CLI tool to identify malicious PyPI packages. Versions prior to 0.1.5 are vulnerable to Relative Path Traversal when scanning a specially-crafted local PyPI package. Running GuardDog against a specially-crafted package can allow an attacker to write an arbitrary file on the machine where GuardDog is executed due to a path traversal vulnerability when extracting the .tar.gz file of the package being scanned, which exists by design in the tarfile.TarFile.extractall function. This issue is patched in version 0.1.5.

Technologies: guarddog (PyPI). Vendors: PyPI.
