Doc Text:
A flaw was found in Junrar, an open-source Java RAR archive library. This vulnerability, a backslash path traversal, allows a remote attacker to write arbitrary files to any location on the filesystem when a specially crafted RAR archive is extracted on Linux/Unix systems. This can lead to remote code execution, enabling an attacker to compromise the system by overwriting critical files such as shell profiles or cron jobs.

Description OSIDB Bzimport 2026-02-26 23:01:57 UTC
Junrar is an open source java RAR archive library. Prior to version 7.5.8, a backslash path traversal vulnerability in `LocalFolderExtractor` allows an attacker to write arbitrary files with attacker-controlled content anywhere on the filesystem when a crafted RAR archive is extracted on Linux/Unix. This can often lead to remote code execution (e.g., overwriting shell profiles, source code, cron jobs, etc). Version 7.5.8 has a fix for the issue.
