rsync is vulnerable to access control bypass. A remote attacker is able to bypass access restrictions as the daemon does not check for fnamecmp filenames in the daemon_filter_list data structure in recv_files function in receiver.c. The sanitize_paths protection mechanism is also not applied to pathnames found in xname follows strings.
