Dec 3, 2024 6:43:27 PM | Product Security Understanding 2023’s Most Exploited Vulnerabilities: Why XIoT Devices Are at Risk

 

The Cybersecurity and Infrastructure Security Agency (CISA) and several other global cybersecurity agencies recently released an advisory identifying 2023’s Top Routinely Exploited Vulnerabilities. Of the 47 vulnerabilities listed—all of which appear in CISA’s Known Exploited Vulnerabilities (KEV) Catalog—more than half impact extended internet of things (XIoT) devices, including network infrastructure, edge devices, and programmable logic controllers (PLCs).

This trend underscores the increasing focus of attackers on XIoT devices, presenting a clear call to action for organizations to enhance their security measures.


Understanding the KEV Catalog and Its Importance

The NetRise Platform integrates with the KEV Catalog to prioritize vulnerabilities in software artifacts. As a refresher, CISA outlines the Catalog’s purpose as follows:

“Known exploited vulnerabilities should be the top priority for remediation. Based on a study of historical vulnerability data dating back to 2019, less than 4% of all known vulnerabilities have been used by attackers in the wild. Rather than have agencies focus on thousands of vulnerabilities that may never be used in a real-world attack, BOD-22-01 shifts the focus to those vulnerabilities that are active threats.”

By focusing on actively exploited vulnerabilities, organizations can maximize the impact of their remediation efforts.


XIoT Devices: A Growing Target

While the KEV Catalog spans a broad range of software, vulnerabilities affecting XIoT devices are increasingly prevalent:

  • In 2022, approximately 30% of CVEs in the KEV Catalog impacted XIoT devices or software components commonly used by these devices.
  • By 2023, this number grew to 34%, and as of November 2024, it stands at 35%.

This steady rise highlights the urgent need for visibility into these devices and their associated software.


Zero-Day Exploits: A Troubling Trend

The 2023 advisory revealed a concerning development:

“In 2023, the majority of the most frequently exploited vulnerabilities were initially exploited as a zero-day, an increase from 2022, when less than half were zero-days.”

This trend has two significant implications:

  1. Longstanding Vulnerabilities Persist
    Despite the rise in zero-day exploits, many vulnerabilities in the KEV Catalog have been known for years. In 2024, 37% of vulnerabilities affecting XIoT devices were discovered more than a year ago. These older vulnerabilities represent a critical opportunity for remediation and risk reduction.

  2. XIoT Devices Remain Prime Targets
    Malicious actors continue to target XIoT, network, and edge devices to establish footholds within their targets. Now more than ever, organizations must gain a comprehensive understanding of their device inventories and the software running on them.
