CVE-2022-32967 is a vulnerability identified in the Realtek RTL8111EP-CG and RTL8111FP-CG network interface controllers, specifically related to the DASH (Desktop and mobile Architecture for System Hardware) function. The issue stems from the use of a hard-coded password embedded within the firmware or software managing the DASH functionality. This hard-coded credential allows an unauthenticated attacker with physical access to the system to exploit the vulnerability during a system reboot initiated by another user. By leveraging this hard-coded password, the attacker can gain access to partial system information such as the device's serial number and server details. The vulnerability is classified under CWE-798, which pertains to the use of hard-coded credentials, a known security weakness that can lead to unauthorized access. The affected versions include unspecified versions up to and including version 5.0.10. No patches or fixes have been publicly disclosed at the time of this report, and there are no known exploits in the wild. The attack requires physical presence and the ability to trigger a system reboot, but does not require authentication or user interaction beyond the reboot event. The impact is limited to information disclosure rather than full system compromise, but the exposure of system identifiers could facilitate further targeted attacks or unauthorized access in complex environments.

For European organizations, the primary impact of CVE-2022-32967 lies in the potential leakage of sensitive system information such as serial numbers and server details. While this does not directly compromise system confidentiality or availability, the disclosed information could be leveraged by attackers to fingerprint devices, bypass security controls, or plan more sophisticated attacks. Organizations with high-value infrastructure relying on Realtek RTL8111EP-CG network controllers, especially in data centers or critical server environments, may face increased risk of targeted physical attacks. The requirement for physical access limits the threat to environments where attackers can gain proximity to hardware, such as shared office spaces, data centers with less stringent physical security, or during maintenance operations. The vulnerability does not allow remote exploitation, reducing the risk of widespread automated attacks. However, the presence of hard-coded credentials undermines security best practices and may violate compliance requirements related to credential management and hardware security. In sectors such as finance, government, and critical infrastructure within Europe, even limited information disclosure can have cascading effects on security posture and incident response.

Given the absence of an official patch, European organizations should implement several targeted mitigations: 1) Enhance physical security controls around servers and network devices using the affected Realtek controllers to prevent unauthorized physical access. This includes locked server rooms, surveillance, and access logging. 2) Monitor and restrict reboot operations to authorized personnel only, ensuring that system restarts are controlled and logged to detect suspicious activity. 3) Conduct an inventory of hardware to identify devices using RTL8111EP-CG or RTL8111FP-CG controllers and assess exposure. 4) Where feasible, disable or restrict DASH functionality if it is not essential for operations, as this may reduce the attack surface. 5) Employ network segmentation and strict access controls to limit the ability of an attacker who gains partial system information to move laterally or escalate privileges. 6) Engage with Realtek or hardware vendors for firmware updates or advisories and plan for hardware replacement if no firmware fix is forthcoming. 7) Incorporate this vulnerability into physical security and incident response training to raise awareness among IT and security staff. These steps go beyond generic advice by focusing on operational controls and hardware-specific risk management.
