CVE-2021-0193 is a high-severity vulnerability affecting Intel(R) In-Band Manageability software versions prior to 2.13.0. The flaw stems from improper authentication mechanisms within the software, which is designed to provide in-band management capabilities for Intel hardware. Specifically, this vulnerability allows a privileged user—someone who already has some level of access—to escalate their privileges further via network access. The vulnerability is classified under CWE-287, indicating an authentication bypass or improper authentication issue. The CVSS v3.1 base score is 7.2, reflecting a high impact on confidentiality, integrity, and availability, with the attack vector being network-based, requiring high privileges but no user interaction. Exploiting this vulnerability could allow an attacker to gain elevated control over the system, potentially leading to unauthorized access to sensitive data, manipulation of system configurations, or disruption of services. Although no known exploits are currently reported in the wild, the nature of the vulnerability makes it a significant risk, especially in environments where Intel In-Band Manageability software is deployed for remote system management. The lack of a patch link in the provided data suggests that users should verify with Intel for the latest updates and apply version 2.13.0 or later to mitigate this issue.

For European organizations, the impact of CVE-2021-0193 can be substantial, particularly for enterprises relying on Intel hardware with in-band management capabilities for remote administration and monitoring. Successful exploitation could lead to unauthorized privilege escalation, enabling attackers to bypass existing security controls and gain deeper access to critical systems. This could compromise sensitive corporate data, intellectual property, and personal data protected under GDPR. Additionally, the integrity and availability of managed systems could be jeopardized, potentially disrupting business operations and critical infrastructure services. Sectors such as finance, telecommunications, government, and manufacturing—where Intel hardware is prevalent—are at heightened risk. The network-based nature of the attack vector means that attackers could exploit this vulnerability remotely, increasing the threat surface. Given the stringent data protection regulations in Europe, any breach resulting from this vulnerability could also lead to significant legal and financial repercussions.

To mitigate CVE-2021-0193 effectively, European organizations should: 1) Immediately verify the version of Intel In-Band Manageability software deployed across their infrastructure and upgrade to version 2.13.0 or later, where the vulnerability is addressed. 2) Implement strict network segmentation and access controls to limit network exposure of management interfaces, ensuring that only authorized and authenticated personnel can access these systems. 3) Employ robust monitoring and logging of management software activities to detect anomalous behavior indicative of privilege escalation attempts. 4) Enforce the principle of least privilege rigorously, minimizing the number of users with high-level privileges that could be leveraged for exploitation. 5) Regularly audit and update authentication mechanisms and credentials associated with management software to prevent misuse. 6) Coordinate with Intel and subscribe to security advisories to stay informed about patches and emerging threats related to this software. These steps go beyond generic advice by focusing on operational controls and proactive management of the affected software environment.
