CVE-2022-4510: Microsoft Binwalk

High severity, CVSS 7.8. EPSS: 22% chance of exploitation in the next 30 days.

A path traversal vulnerability was identified in ReFirm Labs binwalk from version 2.1.2b through 2.3.3 included. By crafting a malicious PFS filesystem file, an attacker can get binwalk's PFS extractor to extract files at arbitrary locations when binwalk is run in extraction mode (-e option). Remote code execution can be achieved by building a PFS filesystem that, upon extraction, would extract a malicious binwalk module into the folder .config/binwalk/plugins. This vulnerability is associated with program files src/binwalk/plugins/unpfs.py. This issue affects binwalk from 2.1.2b through 2.3.3 included.

Affected products

• Microsoft Binwalk: from 2.2.0, before 2.3.3 (fixed in 2.3.3)
