CVE-2024-12747 is a race condition vulnerability in the rsync server implementation affecting versions prior to 3.4.0. The flaw occurs during rsync's handling of symbolic links: although rsync normally skips symbolic links by default, an attacker can exploit a timing window by replacing a regular file with a symbolic link while rsync is processing it. This can cause rsync to traverse the symbolic link despite the intended protection. The issue is server-side and relates to improper symlink handling under race conditions, potentially exposing files outside the intended synchronization scope.
