2020 has been a disaster for many organizations: multiple data breaches, ransomware attacks, and internal threats. After 2020, IT as a department and a role have changed for the good. Leaders are more receptive to the opinions and initiatives of CIO/CISO/IT Head roles. Every IT professional now given more responsibilities for remote IT management. However, there is always an extra component in security that could use some attention. A vulnerability management tool can help prevent these attacks.

The silent criminal

Even though organizations are more sensitive and proactive towards cyber-security, there is always one important component of security that often overlooked. Yes, you guessed it. Vulnerabilities in endpoints. In most cases of cyber-attacks, vulnerabilities serve as entry points to an attacker. However, a patch management tool can patch these vulnerabilities.

Almost all security advisories ever published end with something along the lines of“install all security updates and upgrade to the latest version to be secure.” Even IT professionals sometimes forget how crucial it is to keep endpoints free from vulnerabilities. While the focus on new anti-malware and threat response technologies needed, looking for vulnerabilities and mitigating them goes a long way in preventing attacks in the first place.

Top vulnerabilities of 2020

Every year, around 19,000 vulnerabilities are reported to the National Vulnerability Database(NVD). However, like business risks, security risks can be brought down as low as possible but not entirely eliminated. If you choose your battles correctly, security risks reduced to very minimal levels.

Download our new “Top Vulnerabilities Report 2020”. This report contains a list of endpoint vulnerabilities from January 2020 to December 2020 that have either caused severe damage or pose severe risks.

SecPod’s Security Research Team analyzed all vulnerabilities and narrowed down the options considering two factors:

    1. Critical and High-risk CVSS ratings
    2. Increased exploit activity and potential

The vulnerabilities listed in the report are the most notorious kinds that made last year even worse for us. Mitigating these 20 vulnerabilities will go a long way in bringing down your security risk scores.

Mitigate all the vulnerabilities if you have not yet. Let’s eliminate the bad stuff from 2020 before going any further this year.

Root-Level RCE Flaw in Cisco Nexus 9000 Series Switches Exposes Networks to Complete Compromise — CVE-2026-20212

CVE-2026-20212 is a critical vulnerability in Cisco Nexus 9000 Series Switches that use Silicon One ASICs. It allows an unauthenticated remote attacker to execute code with root privileges by sending crafted input to TCP ports 43210 and 43211, which are reachable in the default Layer 3 VRF. Exploitation can also crash the S1HAL process and force a device reload. This article covers how the vulnerability works, the affected product identifiers, its potential impact, available workarounds, and how to identify fixed software using the Cisco Software Checker.
