Rezilion Unveils Top Threatening Vulnerabilities of 2023 with Focus on Containers & Access Control

Rezilion Reveals Most Threatening Vulnerabilities of 2023 – A Summary


Rezilion, a cybersecurity startup known for its proprietary autonomous DevSecOps platform, has released a report on the most critical security flaws that were discovered in the first half of 2023.

Main Points

The report highlighted the following main points:

  • Vulnerabilities in widely used containers – Docker, Kubernetes and OpenShift – were frequent and particularly dangerous.
  • Authentication and authorization issues were common, including weak passwords and lack of multi-factor authentication.
  • Insufficient input validation, serialization issues and Injection exploits ranked high in the list of vulnerabilities.
  • The research also found a rise in supply chain attacks, where attackers managed to infiltrate third-party software libraries and use them to compromise vulnerable targets.

Vulnerabilities in Containers

Containers are the building blocks of modern DevOps workflows, and Rezilion’s report makes it clear that they can also be the source of major security risks. Vulnerabilities in widely used containers, such as Docker and Kubernetes, were particularly prevalent and problematic during the first half of 2023. Docker, in particular, features prominently in the report, with no less than seven of the top 20 vulnerabilities related to the platform.

Authentication and Authorization Issues

Authentication and authorization issues continue to persist as a security weak spot for organizations. Weak passwords and a lack of multi-factor authentication were among the most common vulnerabilities identified in the report. While these may seem like basic oversights on the part of developers and IT teams, they can be disastrous if exploited by an attacker.

Insufficient Input Validation, Serialization Issues, and Injection Exploits

Other common vulnerabilities in the first half of 2023 included insufficient input validation, serialization issues, and Injection exploits. These flaws arise from poor coding practices and can be exploited to execute arbitrary code or steal sensitive information.

Supply Chain Attacks

The Rezilion report also highlighted an increase in supply chain attacks – a type of cyberattack where hackers exploit a third-party vendor or software supplier to infiltrate a company’s network. This is a growing trend in the cybersecurity space and is not surprising given that organizations are becoming increasingly reliant on third-party vendors to supply software, hardware, and other services.


In conclusion, Rezilion’s report on the most critical security flaws of 2023 provides a wake-up call to developers and IT teams everywhere. Organizations must take proactive measures to address these vulnerabilities, which may seem basic in nature but continue to pose serious risks to their cybersecurity posture. By being vigilant and keeping up-to-date with the latest security best practices, businesses can stay one step ahead of cybercriminals and protect their data from malicious attacks.Original Article:
