Alert: Microsoft presents new vulnerabilities in its products

Teleworking brought many facilities but also many dangers. Among them is the increase in cyber-crime. In this sense, 2021 does not promise cyber security. And as we mentioned in this post, Microsoft products and services contain the majority of vulnerabilities.

Microsoft reports 104 vulnerabilities, 16 of which are critical

According to the National Institute of Cybersecurity in Spain, Microsoft publishes a monthly report with its vulnerabilities. These reports detail the vulnerabilities present in its software products. For example, the November report reported 104 vulnerabilities, 16 of which are critical. The products that could be affected are:

Microsoft Windows:

  • Windows 10 (versions 20H2, 1607, 2004, 1903, 1909, 1809 and 1803);

Critical Hazards

One of the most serious risks presented is the possibility of a cyber-criminal escalating privileges. Consequently, this would result in being able to execute malicious code remotely. Specifically in the network file system of Windows 10. It could also cause memory failures in Internet Explorer 11 and Edge (HTML-based). In addition, it could also generate spoofing. Similarly, denial of service and tampering. The disclosure of information and the circumvention of security measures are also possible.

Some less critical vulnerabilities

Absolutely, taking into account the important risks is fundamental. But it is also essential to consider those products in which vulnerabilities are less critical. And in this way, prevent potential cyber-attacks. Among those reported by Microsoft are:




  • Microsoft Edge (Chromium-based)
  • ChakraCore
  • Microsoft Exchange Server
  • Microsoft Dynamics
  • Microsoft Windows Codecs Library
  • Azure Sphere
  • Windows Defender
  • Microsoft Teams

Cybersecurity is definitely not a game. And even the technological giants are prone to attacks. So, if you’re a Microsoft user, take the necessary precautions. It’s important to remember that the main thing is to invest in technology and cyber-protection software. Otherwise, we are prone to the risks of cyber-threats. To be safe always install best antivirus in your computer.
