DOM XSS in wix.com

JUST REVEALED - November 2, 2016

Wix.com, a hosting provider which claims to host millions of websites, contains an XSS that leads to administrator account takeover and could be used to create a Wix website worm. 

Vulnerability

Wix.com has a severe DOM XSS vulnerability that allows an attacker complete control over any website hosted at Wix. Simply by adding a single parameter to any site created on Wix, the attacker can cause their JavaScript to be loaded and run as part of the target website. 

Here’s an example exploit occurring, causing a reflected payload to occur:

 

UPDATE - November 3, 2016

Contrast published a disclosure about DOM XSS vulnerability in wix.com discovered by Contrast Senior Security Research Engineer, Matt Austin, on November 2, at 8:00 AM PST. 

GOOD NEWS - Sometime between Noon and 3:00 PM PST that same day, Wix appears to have resolved the problem!

MORE GOOD NEWS:  Wix now has a bug bounty program in place to help avoid issues like this in the future. Ya!

The True Cost of "False Positives" in Application Security

2016 FEATURED INFO

Remember the story of the boy who cried wolf?  His pranks were "false alarms" - defined as "a mistaken or intentionally misleading alert that something is wrong and needs attention."  False alarms from application security tools are certainly annoying, but how do they affect the overall economics of an application security program? As it turns out, they make all the difference.

IAST & the Villainous Library Named "commons-httpclient-3.1.jar"

2016 FEATURED INFO

Let’s talk about commons-httpclient-3.1.jar. I get asked about this library all the time. It’s an HTTP communication library. It has a vulnerability in it. It doesn’t handle SSL very well. In fact, it doesn’t really verify you are who the client…

Node Test Bench

October 17, 2016

Intentionally Vulnerable Node Applications

Contrast Maven Plugin

October 17, 2016

This Maven plugin can be used to allow Contrast to discover vulnerabilities in your application during your integration or verification tests. The "install" goal of the plugin is used to download the agent to the /target directory. In order to use the agent, you should add the -javaagent flag to the JVM options of the application that will be monitored by Contrast in the testing lifecycle phases.

Sheepdog

August 26, 2016

Sheepdog is a simple tool to generate normal and attack traffic for OWASP WebGoat. It can be used with security technologies like WAF and RASP in demonstrations and to verify that they are doing a tiny piece of what they are supposed to do. Sheepdog is not intended to be an exhaustive set of security tests. It has some basic SQL injection, XSS, path traversal, and that kind of thing.

Continuous Application Security Handbook

Revised: August 2016

We reject the old paradigm of periodic and serial scanning, hacking, and patching, which has proven expensive and ineffective. Instead, Continuous Application Security (CAS) relies on security instrumentation in every application. This instrumentation provides security visibility, assessment, and protection in real time and in parallel across the entire application portfolio. CAS is a unified program covering the entire software lifecycle, including both development and production, designed to create a clear line of sight from the threat to strong defenses, and ultimately to assurance.

A CAS program empowers ordinary developers to reliably build and operate secure applications and APIs by transforming paper-based security policy and guidance into “security as code” through instrumentation-based security enforcement. CAS also enables development, security, and operations to work together effectively, at the pace of modern software development and at global enterprise scale.  

Cassandra Migration

A simple and lightweight migration tool for Apache Cassandra database that's based on Axel Fontaine's Flyway project. Cassandra Migration works just like Flyway. Plain CQL and Java based migrations are supported. The Java migration interface provides DataStax's Java Driver session.

Contrast DVNR

August 9, 2016

ContrastDvnr 1.0: Utility for displaying information about the IIS Site and applications on the current machine. It creates a report file about the following:

  • Machine Information - OS Version, Processor Speed, Memory Available, .NET versions installed
  • IIS Site Information (IIS7 or newer)
    • Bindings - Ip Address, Port, Binding Information
    • Applications - AppPool, Authentication Mode, .NET Dlls, HttpModules
    • AppPools - .NET Framework version, Pipeline mode, .NET x86/64bit. (AppPools not used by any application are ignored)
  • GAC .NET DLLs. (Microsoft DLLs are ignored)

By default results are written to report.xml file in XML format. JSON or text output format can be chosen instead. Output can also be written to another file or output to the screen.

Contrast REST Client

The Client Is Not Always Right!

June 10, 2016

J’accuse!

I often get the question, “How well does your product handle iOS?” I’d like to explain why I think this question is a warning sign for an application security program.

An unfortunate part of my job is that sometimes I have to explain that people are focusing on the wrong objectives. Here’s my unfortunate dose of reality for today: We all need a perspective adjustment when it comes to “the client.” With Drumpf-esque powers of oversimplification, let’s start by envisioning that half of your apps are server code, and half client code, looking something like this:

Serialization Must Die: Act 2: XStream (Jenkins CVE-2016-0792)

February 24, 2016

NOTE: Before you begin reading, you may want to visit this article for Act 1 of our series – Kryo serialization library and its weaknesses. This piece frames some of the discussion in this blog, but definitely isn’t required reading. XStream is a popular deserialization library. It’s used directly by many popular apps, like the build tool, Jenkins. It’s also used by other popular libraries, like Spring and Struts 2 for unmarshalling XML input into objects.

Serialization Must Die: Act 1: Kryo

February 12, 2016

When @frohoff, @gebl and @breenmachine all combined to melt Java security (in what I’m hereafter conflating under the term “seriapalooza”), I thought about deserialization alternatives. Where are my customers going next? Is there greener grass? We’re going to find out. If the title of my series wasn’t spoiler enough, let me foreshadow more plainly: the grass is brown and dead, everywhere.

A New, Open Source Tool Proves: Even After Patching, Deserializing Will Still Kill You

January 5, 2016

With all the talk about Java serialization vulnerabilities, I thought I'd share a new, open source tool I built for you to download and use, purposely designed to consume all the memory of a target that's deserializing objects -- eventually blowing it up. It’s called jinfinity. jinfinity exploits the fact that deserializers, like many parsers, follow very basic read-until-terminator patterns. jinfinity totally bypasses any of the protections discussed recently around untrusted deserialization.
