It was a "record-breaking year" for common vulnerabilities and exposures (CVEs) logged by security researchers in 2021, according to a National Vulnerability Database (NVD) analysis performed by Redscan, a Top 40 MDR (managed detection and response) provider.Key findings from Redscan's analysis included:More security vulnerabilities have been disclosed in 2021 (at least 18,439) than in any other year to date. On average, more than 50 CVEs have been logged each day in 2021. 90 percent of CVEs discovered in 2021 can be exploited by cybercriminals with limited technical skills. 61 percent of CVEs require no user interaction to exploit. 55 percent of CVEs require no privileges to exploit. 54 percent of CVEs are classified as having "high" availability; cybercriminals can readily access and exploit these vulnerabilities. 53 percent of CVEs have a high confidentiality rating. Cybercrime and security vulnerabilities are constantly evolving, and security teams are struggling to keep pace, Redscan Head of Threat Intelligence George Glass said. However, security teams that plan ahead are well-equipped to combat cybercrime and guard against current and emerging vulnerabilities.
