CVE-2023-7216: Cpio: extraction allows symlinks which enables remote command execution
First published: Wed Nov 15 2023(Updated: )
A path traversal vulnerability was found in the CPIO utility. This issue could allow a remote unauthenticated attacker to trick a user into opening a specially crafted archive. During the extraction process, the archiver could follow symlinks outside of the intended directory, which allows files to be written in arbitrary directories through symlinks.
