On November 25, 2024, the Cybersecurity and Infrastructure Security Agency (CISA) expanded its Known Exploited Vulnerabilities Catalog by adding a new entry that reflects ongoing active exploitation in the wild. This latest entry, designated as CVE-2023-28461, pertains to a serious vulnerability in Array Networks AG's vxAG ArrayOS, characterized as an Improper Authentication Vulnerability. This vulnerability can serve as a convenient entry point for malicious cyber actors, putting organizations at substantial risk.
Through initiatives like Binding Operational Directive (BOD) 22-01, CISA enforces a strict timeline for federal agencies to patch and mitigate these vulnerabilities. Although BOD 22-01 applies specifically to FCEB, CISA strongly recommends that all organizations adopt a similar urgency in addressing these vulnerabilities.
Let's not wait for the other shoe to drop. Instead, take this as an opportunity to shore up defenses, ensuring the safety and integrity of your digital operations. Even a small action, such as a timely update, can make a significant difference in mitigating cyber threats.

The Implications of CVE-2023-28461
Vulnerabilities like CVE-2023-28461 present significant risks to both government systems and the private sector. The nature of this particular flaw relates to how the ArrayOS manages authentication. Improper authentication could allow attackers to gain unauthorized access, leading to the potential compromise of sensitive information or even the entire network. Such vulnerabilities are often lined up like low-hanging fruit, readily targetable by those malicious hackers scouting the digital landscaping for areas of weakness.Understanding Vulnerability Catalogs
CISA's Known Exploited Vulnerabilities Catalog includes Common Vulnerabilities and Exposures (CVEs) that the agency identifies as posing significant threats based on evidence of current exploitation activities. This catalog aims to pressure organizations—particularly Federal Civilian Executive Branch (FCEB) agencies—to prioritize timely remediation. Each vulnerability listed is not just an abstract concern but an actionable item that demands attention to safeguard against active threats.Through initiatives like Binding Operational Directive (BOD) 22-01, CISA enforces a strict timeline for federal agencies to patch and mitigate these vulnerabilities. Although BOD 22-01 applies specifically to FCEB, CISA strongly recommends that all organizations adopt a similar urgency in addressing these vulnerabilities.
Why Timely Remediation Matters
The real challenge lies in understanding the urgency that comes with these warnings. When CISA flags a vulnerability as actively exploited, it's akin to sounding an alarm that danger looms. Organizations are not facing hypothetical risks but rather a real threat that could manifest at any moment.Steps you can take
If you're a Windows user or a part of an organization reliant on the technology affected by this vulnerability, here are some proactive steps you should consider implementing:- Check Your Systems: Verify whether any equipment utilizes vxAG ArrayOS. If you're uncertain whether your organization is affected, an inventory of your assets may be in order.
- Prioritize Patching: If your systems are at risk, prioritize the application of security patches. Make it a part of your regular operating procedures to stay ahead of vulnerabilities.
- Implement Stronger Authentication Methods: Review and strengthen your authentication flows, enhancing the barriers to entry for any unauthorized individuals. Employ multi-factor authentication (MFA) wherever possible.
- Monitor Vulnerability Catalogs Regularly: Regular checks of CISA’s Known Exploited Vulnerabilities Catalog or subscribing to security advisories can keep you informed about threats pertinent to your organization.
- Educate and Train Staff: Human error remains a prevalent factor in security breaches. Security awareness training for employees could significantly reduce susceptibility to breaches.
Conclusion: A Call to Action
CISA's continual updates to the Known Exploited Vulnerabilities Catalog underline the evolving landscape of cybersecurity threats. With threats like CVE-2023-28461 on the rise, users of affected technologies—including those within large organizations or government entities—must approach these vulnerabilities with diligence. The time to assess your cybersecurity posture is now because, as we’ve seen time and again, neglecting these advisories can have dire consequences.Let's not wait for the other shoe to drop. Instead, take this as an opportunity to shore up defenses, ensuring the safety and integrity of your digital operations. Even a small action, such as a timely update, can make a significant difference in mitigating cyber threats.
