Are you troubled by strange hacks in the night?
Do you experience feelings of dread in your basement or attic?
Have you or your friends actually seen a phreak, script kiddie, or fed?
If the answer is yes, then don’t wait another minute. Just pick up the phone and ask for the Pwnton Pack!
And don’t forget, we will be meeting again soon (whether you-know-who wants us too or not ;] )
At the last meeting I showed everyone how to use a format string vulnerability in a password storage app to bypass the master password and pull data out of memory. That is just one way to exploit this type of vulnerability so I challanged everyone at the meeting to get the app I used “code below” to execute their supplied input. The first person to let me know they got it and do a demo get $20! So it pays to be a little early.
#include < stdio.h >
#include < string.h >
int main (int argc, char *argv[])
{
char** spw = "dc414 pwnz";
char text[1025];
strcpy(text, argv[1]);
if (strcmp(text, "asd123")==0) {
printf("Correct the password is %s \n",spw);
return 0;
}
printf(text);
printf(" is wrong\n");
return 0;
}

A few meetings ago i gave a demo on uploading a flash file to file hosting sites that contains a evil XSS payload. Here is my write up on it.
A while back I was doing a penetration test on a friends file hosting service application. His service allowed the uploading of flash files and when you viewed the files detail page it showed you a preview of the flash movie. At the time I knew you could use actionscript to put javascript in a flash file but I was not sure if it would have full access to the DOM and allow us to do evil stuff.
I started messing around in actionscript and came up with this:
After compiling it and uploading, when viewing the preview page I was greeted with a prompt box that had the contents of my cookie for that domain and it was displayed in text with in the flash embed! So, just like that we are able to manufacture a XSS vulnerability on a application that is otherwise secure.
There is some protection for this attack. When you embed a flash file in a web page that you don’t trust you should add the allowScriptAccess param and set it to none. However this can be bypassed easily, just go to the swf file itself and it will still execute the javascript supplied by our swf file. This means to be fully protected you will also need to use a modrewrite rule to force a download when ever someone tries to view a swf file directly.
Here is one example – http://www.ziddu.com/viewfile/22413513/xss.swf.html
Here is another – http://swfchan.org/2335/xss.swf
The May meeting was another great one. Both Ngharo and my self were late because of traffic and junk so darkwind got things started with his popular demo of sniffing pager messages from the air. I Showed up at the tail end and when he was done I started the introductions. It was good to see all the new faces. After everyone talked for about 15 minutes I gave a live demo on using actionscript “flash” to inject a XSS exploit into a other wise secure website. Then Noize took over and gave a interesting live demo of getting IP addresses from contacts on Skype. Then dw5304 showed some of the features in the untangled firewall software. Congrats to ALee for winning the dc414 free junk giveaway!! Here are some pictures I took of the meeting.
ALee and his winnings!
I have discovered two Vulnerabilities in the Cisco DDR2200 ADSL2 Residential Gateway Router. The first vulnerability is that this device responds to UPNP multicast packets and UPNP SOAP requests out side of its local area network. Allowing attackers to forward ports and redirect traffic with out being authenticated, all of which can be exploited using dc414’s Upnp Exploiter.
The second vulnerability is remote command execution in the web based ping function. You can inject a pipe “|” followed by your command and it will get run on the shell and return the results as shown below.
Ping PoC: http://192.168.1.254/waitPingqry.cgi?showPingResult=1&pingAddr=127.0.0.1|ls
dc414 and I are proud to introduce Upnp Exploiter! A Upnp scanner and exploit tool. This tool comes with two main scanning functions and exploit functions.
The first scanning functions is the target scan. Here you can pick a single IP or IP range to find anything that reports back to a UPNP multicast packet sent to the normal UPNP broadcast address “239.255.255.250 on port 1900” If target responds it takes a closer look and sees if it can get the targets UPNP profile letting us know what type of device it is, what UPNP functions it supports, its IP, and other information. When used remotely, this all takes advantage of the fact that the target device violates the UPNP specs and responds to UPNP requests outside of the deices local area network.
The second scanning function only works in a local area network and just sends out a UPNP broadcast. This function is just using the UPNP protocol as intended.
Once a list of UPNP supported devices are found the script mines some information from it like device type, UPNP functions, IP. If its a gateway device it prompts you and asks if you want to attempt to exploit it.
The first option is to forward ports. If doing this LAN side its best to do some network recon with NMAP or something, find some fun services running on a internal server and forward them to the web for later hacking. While gathering information on the device it gets a list of other ports forwarded via UPNP and the devices internal IP. This is supper helpful when doing things on the remote side. One of my personal favs is routing the modems internal port 80 to 81 on WAN. This should give you access to the routers internal web UI for configuration. Most of the time the default creds will work for admin access >:)
This of course violates lots of rfc’s, protocols, and other stuff lol.
The second exploit option tries to turn a gateway device into a proxy. Now this works using IP addresses and one host per port. So if you want to connect to Victim A on port 8 you use the script to forward all data coming in on any port you choose “for now we will say 88” to VA on port 80. So you connect to port 88 on the Victim B “the gateway device” and all the traffic is forwarded to VA on port 80. This also breaks UPNP rules, but who cares.
The last little thing this script does is parse the replies for the unique_service_name() vulnerability and reports to you if it finds anything with some helpful information to aid in exploiting it.
You can get the script from the git page HERE. If you like it please consider donating to dc414 or me (Anarchy Angel – anarchy@new.dc414.org) for taking the time to make such an awesome script 🙂 If anyone would like to help with development please contact Anarchy Angel (me).
Many thanks to Ngharo for help with the regex and list stuff.
Aprils meeting was awesome! Ngharo started us off with room introductions, which was helpful considering all the new faces at this meeting. Next I gave a quick demo of my new tool Upnp Exploiter. Which lead to me disclosing two 0day vulnerabilities in the Cisco DDR2200 ADSL2 Residential Gateway Router “expect more on all this later”! Then dw5304 gave his SNMP demo again and showed all the n00bs how to pwn Cisco routers using SNMP to upload a your own config to them. Then we all started messing around with trying to draw words on an oscilloscope with my arduino. Because of a late start that is all we had time for. Congrats to BigStarHero for winning a Emerson switch board in the free junk giveaway! Here is some pictures from the meeting.
Free junk giveaway big winner!
The March meeting was no let down, we had lots of people and as always great demos. Ngharo got it started with a make your own pringles can cantenna. 9 luck attendees got to make and take home their own cantenna!  Then he kept it going with a quick demo of radio Mobile and how to use it to make a long range wireless mesh network. Then the professor gave a demo on metasploit using a java exploit to root a windows box. dw5304 took over and gave a little demo of a hacked xbox360 and using a laptop to control everything the console does. Here are some pictures from the meeting. Congrats to uberushaximus for winning 100 free hours to AOL high speed!!
Ngharo got this started with going around the room and asking everyone what they have been hacking and what they plan on hacking on next, then talking about some improvements to the dc414 server, such as how it is now fully IPv6 friendly and some improvements to the VPN. Then I gave a demo of how BeEF when used with Metasploit can pwn browsers from the inside out. dw5304 stepped in and showed us how to use the windows 7 UI on windows 8 with out having to worry about updates messing things up. Then Noize stepped up and gave us all a great introduction to Subterfuge, a MITM framework that utilizes arp attacks. Then I attempted to give another demo but failed, more on that later 😉 We spent the rest of the night drinking, eating cupcakes “thanx darkwinds wife” and loling at horror pics of server rooms and wiring closets. Congrats to Castor, Tony, and Peppergomez for winning the dc414 free junk giveaway!! Enjoy your junk guys 😛
We got $42 in donations which paid for the pizza and some of the beer with nothing left over for the server :/ which cost about $71 a month. Remember your donations are what keeps dc414 running smoothly for YOU!!!!
