Path Traversal in rsync --inc-recursive Client File Handling
CVE-2024-12087 is a path traversal vulnerability in rsync affecting versions 3.3.0 and earlier, and more specifically described in the provided content as affecting versions >= 3.2.7 and < 3.4.0. The issue is triggered when rsync operates with the --inc-recursive option, which is enabled by default for many client operations and can also be enabled by a server even if the client did not explicitly request it. Due to insufficient symlink verification combined with deduplication checks performed on a per-file-list basis, a malicious rsync server can cause the client to create unsafe symlinks or write files outside the client’s intended destination directory. In practice, this allows attacker-controlled path elements to escape the expected synchronization target and place files at arbitrary client-side locations corresponding to valid directories or paths on the client system.
