1) Path traversal

EUVDB-ID: #VU67583

Risk: High

CVSSv4.0: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2007-4559

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to improper validation of filenames in the tarfile module in Python. A remote attacker can create a specially crafted archive with symbolic links inside or filenames that contain directory traversal characters (e.g. "..") and overwrite arbitrary files on the system.

Mitigation

Update the affected package python39 to the latest version.
