- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Junrar is an open source java RAR archive library. Prior to version 7.5.10, a path traversal vulnerability in `LocalFolderExtractor` allows an attacker to write arbitrary files with attacker-controlled content into sibling directories when a crafted RAR archive is extracted. Version 7.5.10 fixes the issue.
