Authentication Bypass in NVIDIA NVOS for Network Switches

Publication date: 2026-08-18

Last updated on: 2026-08-18

Assigner: NVIDIA Corporation

Description
NVIDIA NVOS for network switches contains a vulnerability in the secure shell (SSH) server configuration component while PKA-only mode is enabled, where an administrator could inadvertently enable an alternative authentication path. If best practices for replacing the default password as recommended by NVIDIA are not followed, this alternative authentication path might lead to unauthorized access. A successful exploit of this vulnerability might lead to escalation of privileges.

Executive Summary

This vulnerability exists in NVIDIA NVOS for network switches when PKA-only mode is enabled. It involves an alternative authentication path in the SSH server configuration that an administrator might accidentally enable. If default passwords are not replaced as recommended by NVIDIA, this flaw could allow unauthorized access to the system.

Detection Guidance

Check if PKA-only mode is enabled on NVIDIA NVOS switches and verify SSH server configurations for unintended alternative authentication paths. Inspect logs for unauthorized access attempts or privilege escalation events. Use NVIDIA's recommended tools or scripts to scan for misconfigured SSH settings.

Impact Analysis

Exploitation of this vulnerability could lead to unauthorized access and privilege escalation on affected NVIDIA NVOS systems. Attackers might gain control over network switches, potentially disrupting network operations or compromising sensitive data.

Compliance Impact

This vulnerability could lead to unauthorized access, potentially violating data protection requirements under GDPR and HIPAA. Unauthorized access to network switches may expose sensitive data, leading to non-compliance with these regulations.

Mitigation Strategies

Disable PKA-only mode if enabled. Replace default passwords with strong, unique credentials as per NVIDIA's best practices. Restrict SSH access to trusted networks and monitor for suspicious activity. Apply the latest NVOS updates to affected versions (0.0 to 25.0.2.4438 on GB300 or 0.0 to 25.0.2.6077 on IBSwitch XDR).
