IP KVM Security Risks: BIOS-Level Access and Emerging Vulnerabilities

Administrators widely utilize Internet Protocol Keyboard, Video, and Mouse (IP KVM) switches for remote server management, offering convenient BIOS-level access. However, recent security research reveals significant vulnerabilities in these devices, potentially granting attackers broad network access. These vulnerabilities, reminiscent of early IoT security failures, pose a serious risk to network infrastructure.

What are IP KVMs and Why are They Used?

IP KVMs are compact devices, often costing between $30 and $100, that allow administrators to remotely access and control servers as if they were physically present. Unlike traditional remote access tools like Remote Desktop Protocol (RDP) or Secure Shell (SSH), IP KVMs operate independently of the operating system, providing access at the BIOS/UEFI level – the firmware that runs before the OS loads. KVMGalore explains that this BIOS-level access is crucial for system administrators needing to configure or reconfigure computer hardware, run diagnostics, or manage systems even when the OS is unavailable.

The Emerging Security Threats

On March 12, 2026, Eclypsium researchers disclosed nine vulnerabilities across IP KVMs from four manufacturers. Ars Technica reports that the most critical flaws allow unauthenticated hackers to gain root access or execute malicious code on the targeted systems. These vulnerabilities aren’t complex, zero-day exploits; rather, they stem from fundamental security oversights such as inadequate input validation, lack of authentication, and missing cryptographic verification.

According to Eclypsium, the issues echo the security problems seen in early Internet of Things (IoT) devices, but with potentially more severe consequences due to the BIOS-level access these devices provide. The researchers emphasize that an IP KVM effectively offers the equivalent of physical access to any connected system.

Vulnerable Manufacturers and CVE Details

As of March 17, 2026, Eclypsium has identified vulnerabilities in products from the following manufacturer:

• GL-iNet: Comet RM-1 (CVE-2026-32290) – Insufficient verification of firmware authenticity. A fix is currently being planned.

Mitigating the Risks

Given the potential severity of these vulnerabilities, organizations using IP KVMs should take immediate steps to mitigate the risks:

• Implement Strong Authentication: Ensure all IP KVMs are protected with strong, unique passwords and multi-factor authentication where available.
• Network Segmentation: Isolate IP KVMs on a separate network segment to limit the potential blast radius of a compromise.
• Firmware Updates: Apply firmware updates as soon as they become available from the manufacturer.
• Regular Security Audits: Conduct regular security audits of IP KVM configurations and network access controls.
• Monitor for Suspicious Activity: Implement monitoring systems to detect and alert on any unusual activity related to IP KVM access.

Expanding KVM Capabilities: UEFI Support in RHEL KVM

Whereas security concerns surrounding IP KVMs are paramount, the broader KVM (Kernel-based Virtual Machine) technology is also evolving. Red Hat Enterprise Linux’s (RHEL) KVM allows for the creation of virtual machines capable of booting UEFI-only systems. Make Tech Easier details how enabling UEFI in RHEL KVM is essential for running modern operating systems like Windows 11 in a virtual environment and for testing OS configurations.

Conclusion

IP KVMs offer valuable remote management capabilities, but the recent disclosure of significant security vulnerabilities underscores the importance of proactive security measures. Organizations must prioritize securing these devices to prevent potential network compromises. As KVM technology continues to advance, with features like UEFI support in RHEL KVM, a strong security posture remains critical for leveraging its benefits safely and effectively.
