Impact
Attackers can overwrite arbitrary system files and potentially achieve remote code execution if a user processes a malicious archive. An attacker requires network adjacent access or a method to deliver a poisoned TAR file that an application or user subsequently extracts.
Root cause
The archive extraction logic fails to sanitize dot-dot (..) path traversal sequences within filenames inside TAR archives.
Affected systems
HPE NonStop Python 3.x; exact patch release ranges are not listed in the provided data — check the vendor advisory.
CVSS v3.1 · CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Fix & remediation
Upgrade to the patched version of HPE NonStop Python specified in HPE advisory hpesbns05148en_us. If immediate upgrading is not possible, avoid extracting untrusted TAR archives or validate extracted file paths in Python scripts before writing them to disk.
AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
NVD description
A directory traversal vulnerability in HPE NonStop Python 3.x could allow attackers to overwrite arbitrary files via a .. (dot dot) sequence in filenames in a TAR archive.
