Vulnerability subscriptions in terms of business

The question is: do we really need an employee in organization that deals with vulnerabilities in infrastructure on a full-time basis? Since this is similar to what I do for living, I would naturally say that yes, it is necessary. But as person, who makes security automation, I can say that there are some options. 😊

Vulners Subscriptions

What can and can’t Vulnerability Assessment (VA) specialist do?

VA specialist makes recommendations to remove vulnerabilities from your infrastructure using some tools: vulnerability scanners, vulnerability feeds, different news sources. In case of network vulnerabilities, he will most often tell your IT administrators: “Do we use A software with version BBB? As I see some security bulletin says that there is a critical vulnerability in it”. That’s it.

VA specialist by himself usually don’t patch the hosts. Moreover, sometimes he can’t detect the vulnerability, even he has an expansive vulnerability scanner, because some vulnerabilities can only be detected locally during authenticated scanning, and this IS specialist may not have permissions to do it.

CISO Forum 2017

Last week I have attended CISO Forum 2017 in Moscow.

CISO FORUM 2017: Austere weekdays of CISO

I was talking there about “Vulnerability Quadrants: automated hot topic detection in public vulnerability (CVE) flow”. I will write detailed post on this topic later. Today I want to share my impressions about the forum itself.

Vulnerability Quadrants: automated hot topic detection in public vulnerability (CVE)

To be short, I liked it very much. Both exhibition and presentations.

Vulners Subsriptions and Apache Struts RCE

If you work in IT Security Department of any large software developing company, you were probably searching for Apache Struts in your environment on this week.

And it’s all because of CVE-2017-5638:

Apache Struts is a free, open-source, Model-View-Controller (MVC) framework for creating elegant, modern Java web applications, which supports REST, AJAX, and JSON.
In a blog post published Monday, Cisco’s Threat intelligence firm Talos announced the team observed a number of active attacks against the zero-day vulnerability (CVE-2017-5638) in Apache Struts

This is a good example, that shows the usefulness of the Vulners.com service.

Just open cvelist:CVE-2017-5638 query and you will see all the objects related to this issue. This request works even before this CVE number appear on NVD and Mitre databases!

Vulners Apache Struts2 RCE

Here are: description of the vulnerability from The Hacker News, manual on how to use this vulnerability to gain server access from myhack58, Nessus local windows and remote cgi detection plugins.

Vulners.com and ranges of dates

I have already wrote earlier how to automatically retrieve data from the Vulners.com vulnerability database: if you need objects of some particular type, it’s better use Collection API, if you want to get different types of objects using advanced queries, your choice is Search API v.3.

But what if we want to get, not all the objects, but only new or modified ones in a some date range? How can we do it in Vulners?

Vulners.com date ranges

Search queries

Each object in Vulners (vulnerability, patch, bulletin, etc.) has a publication date, and modification date. You can see it if you open some Vulners object in json format, for example CVE-2017-6301:

        "published": "2017-02-23T23:59:00",
        "modified": "2017-02-24T14:45:17",

Divination with Vulnerability Database

Today I would like to write about a popular type of “security research” that really drives me crazy: when author takes public Vulnerability Base and, by analyzing it, makes different conclusions about software products or operating systems.

CVE Numbers their occult power and mystic virtues

The latest research of such type, was recently published in CNews – a popular Russian Internet portal about IT technologies. It is titled ““The brutal reality” of Information Security market: security software leads in the number of holes“.

The article is based on Flexera/Secunia whitepaper. The main idea is that various security software products are insecure, because of amount of vulnerability IDs related to this software existing in Flexera Vulnerability Database. In fact, the whole article is just a listing of such “unsafe” products and vendors (IBM Security, AlienVault USM and OSSIM, Palo Alto, McAfee, Juniper, etc.) and the expert commentary: cybercriminals may use vulnerabilities in security products and avoid blocking their IP-address; customers should focus on the security of their proprietary code first of all, and then include security products in the protection scheme.

What can I say about these opuses of this kind?

They provide “good” practices for software vendors:

  • Hide information about vulnerabilities in your products
  • Don’t release any security bulletins
  • Don’t request CVE-numbers from MITRE for known vulnerabilities in your products

And then analysts and journalists won’t write that your product is “a leader in the number of security holes”. Profit! 😉
