Vulners.com vulnerability detection plugins for Burp Suite and Google Chrome

What is the main idea of version-based vulnerability detection, especially for Web Applications? With an access to the HTTP response (html, headers, scripts, etc.), you can get the name and version of some standards web application (e.g. CMS, CRM, wiki, task tracker) or names and versions of software components that this web application uses: web server, libraries, frameworks, and so on.

Vulners plugins for Burp Suite Professional and Google Chrome

Next step is to get all known vulnerabilities and exploits  for this software. This is the typical task for Vulners.com – largest database and security content searching system (see “Vulners – Google for hacker“).

So, guys from Vulners Team made a set of useful regular expressions for detecting software names and versions – https://vulners.com/api/v3/burp/rules.  You can use this rules in your own scripts and if you want something that will work out of the box, you can try existing plugins for Burp Suite and Google Chrome.

In this post I would like to show how the detection rules work, present new Vulners Burp API and vulnerability detection plugins for Burp Suite and Google Chrome.

Vulnerability Management for Network Perimeter

Network Perimeter is like a door to your organization. It is accessible to everyone and vulnerability exploitation does not require any human interactions, unlike, for example, phishing attacks. Potential attacker can automate most of his actions searching for an easy target. It’s important not to be such of target. 😉

Vulnerability Management for Network Perimeter

What does it mean to control the network perimeter? Well, practically this process consist of two main parts:

  • Assessing network hosts that are facing Internet using some Network Scanner (Nessus, OpenVAS, Qualys, MaxPatrol. F-Secure Radar, etc.)
  • Assessing application servers, e.g. Web Servers, on these hosts using some special tools, e.g. Web Application Scanners (Acunetix, Burp Suite, Qualys WAS, Tenable.io WAS, High-Tech Bridge ImmuniWeb, etc.)

Active scanning is a good method of perimeter assessment. Dynamics of the assets is relatively low, comparing with the Office Network. Perimeter hosts usually stays active all the time, including the time when you are going to scan scanning them. 😉

Most of the dangerous vulnerabilities can be detected without authorization: problems with encryption (OpenSSL Heartbleed, Poodle, etc.). RCE and DoS of web servers and frameworks (Apache Struts and Equifax case)

The best results can be achieved with scanners deployed outside of your network. Thus, you will see your Network Perimeter the same way a potential attacker sees it. But certainly, you will be in a better position:

  • You can ask your IT administrators to add your network and WAS scanners in white list, so they will not be banned.
  • You can check and correlate scan results of remote scanner with (authenticated?) scan results produced by the scanner deployed in your organization’s network and thus filtering false positives.

What about the targets for scanning? How should you get them?

ZeroNights 2017: back to the cyber 80s

Last Friday, 17th of November, I attended the ZeroNights 2017 conference in Moscow. And it was pretty awesome. Thanks to the organizers! Here I would like to share some of my impressions.

my photo ZeroNights 2017

First of all, I want to say that two main Moscow events for information security practitioners, PHDays and ZeroNights, provide an excellent opportunity to meet all of the colleagues at once and to synchronize current views on important information security issues, including, of course, Vulnerability Management, the most relevant for me. My opinion is that this year’s behind-the-scene conversations were especially good. And this is the most valuable characteristic for the event.

Every ZeroNights event has it’s own style. This time it was some geeky cyber retro from 1980s, like in popular cult movie Kung Fury. The place was also changed from familiar Cosmos Hotel  to ZIL Culture Centre. It is the largest Palace of Culture from the Soviet Moscow times. The combination of US 80s cultural artifacts, RETROWAVE music with Soviet-style interiors (including, for example, statue of Lenin) made a pretty weird combination, but I liked it =)

I was unintentionally taking photos using some strange mode in camera and recorded a very short video fragment (3-5 seconds) for each photo. I decided to combine this fragments in a small video. This does not make much sense, but, perhaps, someone will find this “time-lapse” interesting 😉

Among the great presentations and workshops, there were also a small exhibition. This year there was two Vulnerability Management vendors: Beyond Security and Qualys.

Burp Suite Free Edition and NTLM authentication in ASP.net applications

As you know, Burp Suit is a scanner for advanced Web Application Security researchers. However, the free version of Burp is more like Firebug analogue, but much more functional.

Let’s see how to install it and use for website analysis. This analysis may be necessary to find vulnerabilities or somehow automate the work with the site. Let’s take, for example, ASP.net applications with NTLM-authorization, which is rather unpleasant to analyze.

Go to the site https://portswigger.net/burp/freedownload and download burp installer as a bash script:
