In 2015, a vulnerability scanner identified over 2 million vulnerabilities across more than 20,000 websites worldwide, revealing that the number and severity of vulnerabilities often correlate with the website's size and various factors. Vulnerabilities are categorized by severity using the Common Vulnerability Scoring System (CVSS), with red indicating critical issues (CVSS score ≥ 6), yellow for medium severity (CVSS score between 3 and 6), and blue for low severity (CVSS score between 0 and 3). Initial scans typically reveal a prevalence of medium and low-severity vulnerabilities, such as Missing DNSSEC and SSL BEAST, while more severe vulnerabilities like Login Cross Site Request Forgery (CSRF/XSRF) appear less frequently but remain critical. Over time, the composition of vulnerabilities changes, yet certain critical vulnerabilities, including Email Spoofing, Web Server Vulnerabilities, and Cross Site Scripting, persist as significant threats. The analysis aims to provide insights into common website vulnerabilities to aid in addressing potential security weaknesses effectively.
