CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2022-23531 – Arbitrary file write when scanning a specially-crafted local PyPI package
https://notcve.org/view.php?id=CVE-2022-23531
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. GuardDog es una herramienta CLI para identificar paquetes PyPI maliciosos. • https://github.com/DataDog/guarddog/pull/89/commits/a56aff58264cb6b7855d71b00dc10c39a5dbd306 https://github.com/DataDog/guarddog/releases/tag/v0.1.5 https://github.com/DataDog/guarddog/security/advisories/GHSA-rp2v-v467-q9vq • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-23: Relative Path Traversal •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 2CVE-2022-23530 – GuardDog vulnerable to arbitrary file write when scanning a specially-crafted remote PyPI package
https://notcve.org/view.php?id=CVE-2022-23530
GuardDog is a CLI tool to identify malicious PyPI packages. Versions prior to v0.1.8 are vulnerable to arbitrary file write when scanning a specially-crafted remote PyPI package. Extracting files using shutil.unpack_archive() from a potentially malicious tarball without validating that the destination file path is within the intended destination directory can cause files outside the destination directory to be overwritten. This issue is patched in version 0.1.8. Potential workarounds include using a safer module, like zipfile, and validating the location of the extracted files and discarding those with malicious paths. • https://github.com/DataDog/guarddog/blob/a1d064ceb09d39bb28deb6972bc0a278756ea91f/guarddog/scanners/package_scanner.py#L153..158 https://github.com/DataDog/guarddog/commit/37c7d0767ba28f4df46117d478f97652594c491c https://github.com/DataDog/guarddog/security/advisories/GHSA-78m5-jpmf-ch7v • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
