CVE-2024-12087

This vulnerability is classified as Path Traversal (CWE-22), which allows attackers to access files and directories outside the intended path. A path traversal vulnerability exists in rsync. It stems from behavior enabled by the `--inc-recursive` option, a default-enabled option for many client options and can be enabled by the server even if not explicitly enabled by the client. When using the `--inc-recursive` option, a lack of proper symlink verification coupled with deduplication checks occurring on a per-file-list basis could allow a server to write files outside of the client's intended destination directory. A malicious server could write malicious files to arbitrary locations named after valid directories/paths on the client. Affected products include: Samba Rsync, Almalinux, Archlinux Arch Linux, Gentoo Linux, Nixos.
