A path traversal vulnerability was identified in ReFirm Labs binwalk from version 2.1.2b through 2.3.3 inclusive. 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 and including 2.3.3.
