CVE-2024-12087 is a path traversal vulnerability in rsync affecting versions prior to 3.4.0. The flaw arises 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. Under this mode, rsync fails to properly verify symbolic links, while deduplication checks are performed on a per-file-list basis. This combination can allow a malicious rsync server to cause file writes outside the client’s intended destination directory by targeting paths that correspond to valid directories on the client system. The issue is client-side in effect: a hostile server can influence where received content is written on the connecting client.
