Problem Description:
The ftpd(8) server splits long commands into several
requests. This may result in the server executing a command
which is hidden inside another very long command.
Impact:
This could, with a specifically crafted command, be used in a
cross-site request forgery attack.
FreeBSD systems running ftpd(8) server could act as a point
of privilege escalation in an attack against users using web
browser to access trusted FTP sites.
Workaround:
No workaround is available, but systems not running FTP
servers are not vulnerable. Systems not running the FreeBSD
ftp(8) server are not affected, but users of other ftp
daemons are advised to take care since several other ftp
daemons are known to have related bugs.
