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.
WFTPD and WFTPD Pro 2.41 allows remote attackers to cause a denial of service by using the RESTART (REST) command and writing beyond the end of a file, or writing to a file that does not exist, via commands such as STORE UNIQUE (STOU), STORE (STOR), or APPEND (APPE).
WFTPD and WFTPD Pro 2.41 allows remote attackers to obtain the real pathname for a file by executing a STATUS (STAT) command while the file is being transferred.
WFTPD and WFTPD Pro 2.41 allows local users to cause a denial of service by executing the RENAME TO (RNTO) command before a RENAME FROM (RNFR) command.
