Excessive-severity and important bugs disclosed in 2020 outnumber the sum whole of vulnerabilities reported 10 years prior
An evaluation of information collected by america’ Nationwide Institute of Requirements and Expertise (NIST) about widespread vulnerabilities and exposures (CVEs) has discovered that 2020 noticed extra experiences of safety loopholes than every other yr thus far.
The report by Redscan, a supplier of managed safety providers, reveals that 18,103 vulnerabilities had been reported final yr, with most (10,342) labeled as excessive or crucial in severity. Actually, high-severity and important bugs disclosed in 2020 outnumbered the sum whole of vulnerabilities disclosed in 2010.
Among the many key findings was a surge in safety flaws that don’t require any consumer interplay. These accounted for 68% of all CVEs reported to NIST in 2020. “Safety professionals must be involved about the truth that greater than two-thirds of vulnerabilities recorded in 2020 require no consumer interplay of any variety to take advantage of. Attackers exploiting these vulnerabilities don’t even want their targets to unwittingly carry out an motion, resembling clicking a malicious hyperlink in an e-mail. Which means assaults can simply slip below the radar,” warned Redscan.
There are a number of outstanding examples of such vulnerabilities, together with a crucial distant code execution flaw listed as CVE-2020-5902 that affected F5 Networks’ BIG-IP multi-purpose networking devices.
The share of safety loopholes that don’t require any consumer privileges dropped from 71% in 2016 to 58% in 2020; in the meantime, the variety of vulnerabilities that require high-level privileges has been on the rise. This interprets into extra effort from cybercriminals who will resort to time-tested basic assaults resembling phishing when focusing on high-value marks.
“Customers with a excessive diploma of privileges, resembling system directors, are a prize goal as a result of they’re able to open extra doorways for attackers,” Redscan defined.

The report goes on to stipulate different elements of vulnerabilities past severity that folks must be cautious of. Some 4,000 flaws had been discovered to satisfy the so-called “worst of the worst” circumstances; these are CVEs which have a low assault complexity, don’t require any privileges or consumer interplay, and have confidentiality designated as excessive.
Redscan concludes its findings on a somber word, highlighting that though crucial and excessive severity vulnerabilities must be on the forefront more often than not, safety groups “shouldn’t lose sight of lower-level vulnerabilities”.
“When analysing the potential danger that vulnerabilities pose, organisations should take into account extra than simply their severity rating. Many CVEs are by no means or hardly ever exploited in the true world as a result of they’re too advanced or require attackers to have entry to excessive degree privileges. Underestimating what seem like low danger vulnerabilities can go away organisations open to ‘chaining’, wherein attackers transfer from one vulnerability to a different to progressively achieve entry at more and more crucial levels,” said George Glass, Head of Risk Intelligence at Redscan.
