Directory traversal vulnerability in Winsock FTPd (WFTPD) 3.00 and 2.41 with the "Restrict to home directory" option enabled allows local users to escape the home directory via a "/../" string, a variation of the .. (dot dot) attack.
WFTPD and WFTPD Pro 2.41 RC12 allows remote attackers to obtain the full pathname of the server via a "%C" command, which generates an error message that includes the pathname.
