Nowadays, the number of discovered vulnerabilities increases rapidly. In 2018, the 17, 308 vulnerabilities were discovered and during the 2019 even more, so up to 20, 362. The serious problem is that a substantial part of them is rated as critical or at least labeled as high according the CVSS (Common Vulnerability Scoring System). This fact causes a problem, the designers and/or developers do not know which vulnerability should be eliminated at the first place. Time for removal of the vulnerability is crucial from the practical point of cyber security. The main contribution of the article is a proposal of a new method that is used for prioritizing vulnerabilities. The aim of the proposed method is to eliminate the disadvantages of approaches commonly used today. Our method improves the prioritization of vulnerabilities utilizing the parameters: the possibility of exploitation, availability of information about them and knowledge obtained by Threat Intelligence. These three parameters are highly important, especially for newly discovered vulnerabilities, where a priority can differ from day to day. We evaluate the functionality of the proposed method utilizing the production environment of a medium-sized company and we copare results with CVSS method (30 servers, 200 end-stations).
