WFTPD Pro MKD or XMKD FTP commands can cause denial of service
|wftpd-ftp-command-dos (15342)||Medium Risk|
WFTPD Pro Server is vulnerable to a denial of service, caused by a stack-based buffer overflow. A remote authenticated attacker, who has logged in with the XeroxDocutech option set to 1, can supply a specially-crafted MKD or XMKD FTP command to overflow the buffer and cause the server to crash.

Upgrade to the latest version of WFTPD (version 3.21 R2 or later), available from the Texas Imperial Software Web site. See References.
