CVE-2022-23531
GuardDog vulnerable to arbitrary file write when scanning a specially-crafted PyPI package
Impact
### Impact Running GuardDog against a specially-crafted package can allow an attacker to write an arbitrary file on the machine where GuardDog is executed. This is 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. See also https://docs.python.org/3/library/tarfile.html#tarfile.TarFile.extractall ### Remediation Upgrade to GuardDog v0.1.5 or more recent. ### References * https://semgrep.dev/r?q=trailofbits.python.tarfile-extractall-traversal.tarfile-extractall-traversal * https://www.trellix.com/en-us/about/newsroom/stories/research/tarfile-exploiting-the-world.html * https://docs.python.org/3/library/tarfile.html#tarfile.TarFile.extractall
