Vulnerability Management at Tinkoff Fintech School

In the last three weeks, I participated in Tinkoff Fintech School – educational program for university students. Together with my colleagues, we prepared a three-month practical Information Security course: 1 lecture per week with tests and home tasks.

Each lecture is given by a member of our security team, specialized in one of the following modules: Vulnerability Management, Application Security, Infrastructure Security, Network Security, Virtualization Security, Banking Systems Security, Blue & Red-teaming, etc.

The course is still ongoing, but my Vulnerability Management module is over. Therefore, I want to share my impressions and some statistics.

New vulnersBot for Telegram with advanced searches and subscriptions

Vulners.com team have recently presented a new version of vulnerability intelligence bot for Telegram messenger. Now you can search for vulnerabilities and other security content by talking with bot.

For example, I’ve heard about new critical vulnerability in Samba called SambaCry by analogy with famous WannaCry. Let’s see what Vulners knows about it.

Vulners – Google for hacker. How the best vulnerability search engine works and how to use it

The common task. Уou need to find all information about some vulnerability: how critical the bug is, whether there is a public exploit, which vendors already released patches, which vulnerability scanner can detect this bug in the system. Previously, you had to search it all manually in dozens of sources (CVEDetails, SecurityFocus, Rapid7 DB, Exploit-DB, CVEs from MITRE / NIST, vendor newsletters, etc.) and analyze the collected data. Today, this routine can be (and should be!) automated with specialized services. One of these services – Vulners.com, the coolest search engine for bugs. And what is the most important – it’s free and has an open API. Let’s see how it can be useful for us.

What is it?

Vulners is a very large constantly updating database of Information Security content. This site lets you search for vulnerabilities, exploits, patches, bug bounty programs the same way a web search engine lets you search for websites. Vulners aggregates and presents in convenient form seven major types of data:

  • Popular vulnerability databases, containing general descriptions of vulnerabilities and links. For example, well-known NVD CVEs of MITRE US agency and NIST Institute. In addition to this, Vulners supports vulnerability descriptions from various research centers and response teams: Vulnerability Lab, XSSed, CERT, ICS, Zero Day Initiative, Positive Technologies, ERPScan.
  • Vendor’s security bulletins. This bug-reports are published by software vendors and contain information about vulnerabilities in their own products. At current moment Vulners supports various Linux distributions (Red Hat, CentOS, Oracle Linux, Arch Linux, Debian, Ubuntu, SUSE), FreeBSD, network devices (F5 Networks, Cisco, Huawei, Palo Alto Networks), popular and critical software (OpenSSL, Samba, nginx, Mozilla, Opera), including CMS (WordPress, Drupal).
  • Exploits from Exploit-DB, Metasploit and 0day.today. Exploits are parsed and stored in full-text form and you can read the sources in a convenient text editor.
  • Nessus plugins for vulnerability detection. It makes easy to find out whether a particular vulnerability can be detected using this popular network scanner. Why is it important? Read in my article “When a free scanning service detects vulnerabilities better“.
  • Bug disclousers for bug bounty programs. At current moment Vulners supports HackerOne and Open Bug Bounty.
  • Potential vulnerabilities of mobile applications and CMS. It is possible in cooperation with the static application security testing (SAST) vendors Hackapp and InfoWatch APPERCUT.
  • Posts from hacking resources. Vulners collects Threatpost and rdot.org publications, which often cover vulnerability related topics.

All this information is handled, cataloged, structured and is always available for the search.
