Right..

/* Windows 2003 <= remote RPC DCOM exploit
 * Coded by .:[oc192.us]:. Security
 * Modified by rogers@efnet
 *
 * Features:
 *
 * -d destination host to attack.
 *
 * -p for port selection as exploit works on ports other than
135(139,445,539 etc)
 *
 * -r for using a custom return address.
 *
 * -t to select target type (Offset) , this includes universal offsets

for -

 *    win2k and winXP (Regardless of service pack)
 *
 * -l to select bindshell port on remote machine (Default: 666)
 *
 * - Shellcode has been modified to call ExitThread, rather than
ExitProcess, thus
 *   preventing crash of RPC service on remote machine.
 *
 * Modification:
 *
 *  AUTOROOTER
 *
 *  Modify the commands in *cmd, in void con(int sockfd){} 3rd line
 *  I suggest having it ftp to a box and download a backdoor, run it,

then

exit.
 *
 * Works well with this class C (B /16 or A /8 as well) command line

scanner

using nmap:
 *
 * /usr/bin/nmap -sS -p 135 -oG out $1/24
 * for i in `cat out | grep open | awk '{print $2}'`; do
 * ./rogers-oc192-dcom -d $i -t 1&
 * ./rogers-oc192-dcom -d $i -t 0&
 * done
 *
 *
 * sh scan.sh 10.10.2.0
 *
 * Happy owning!

Subject: Re: [Full-disclosure] Cox is blocking port 135 - off topic



cox does block port 445 also, but i havent seen any
exploits that use that port. even though its said that
port 445 is vulnerable, where is the POC?

Off topic:

This won't help much at all. Windows 2000/XP run
Microsoft SMB over TCP on
445 as well (reduced overhead then 135/etc, no
NetBIOS layer). When a client
tries to connect to a remote host for file/print
sharing/etc it connects on
both ports 135 and 445, if a response is recieved
from port 445 it drops the
connection to 135. THe attack works quite well
against client systems using
port 445. If Cox blocks both ports 135 and 445 that
will be semi-effective
(except of course for internal users who spread a
worm/etc, such as laptops
that move around). THis may block a few of the more
stupid attacks but not
for long.
