Maksymilian Arciemowicz has reported a vulnerability in NetBSD ftpd, which can be exploited by malicious people to conduct cross-site request forgery attacks.
The vulnerability is caused due to the application truncating an overly long FTP command, and improperly interpreting the remainder string as a new FTP command. This can be exploited to execute arbitrary FTP commands with the privileges of another user by e.g. tricking the user into following a malicious link.
Solution: Fixed in the CVS repository. See vendor advisory for details.
