CVE-2025-46394

Archive-content masking via unescaped terminal sequences

Published Apr 23, 2025 · Updated Jun 2, 2026

UI misrepresentation in BusyBox tar through 1.37.0 allows local users to hide archive filenames from terminal listings via crafted names. The header_list and header_verbose_list paths print attacker-controlled filenames and link targets without replacing terminal-control bytes. Exploitation requires listing a crafted TAR archive in an interactive terminal; entries can be concealed before extraction, including on RUGGEDCOM RST2428P before 4.0.
