DOS PC FTP SERVER

[etorres () pollux javeriana edu co (Efrain Torres Mejia)]

Ok, so here is another stupid bug.


Im sure this will work on others pc ftp servers for windoze

Impact: Anybody from outside can shutdown your pc ftp server.
        And if u are under win3.1 the system will crash.


Program: WinQVT/NET
Version: All versions.. 16 and 32 bits

Solution.. dont use it or upgrade

Exploit: Just Send a OOB (Out of Band) to port 21,

Exploit for dummies: Take any winnuke, open it and read the code,
                     when u find a "139" change it for a "21".
                     OK.

I know this is stupid....... :P. But maybe somebody will need it.. who
knows...
