CVE-2021-0126 is a high-severity vulnerability affecting Intel(R) Manageability Commander versions prior to 2.2. The vulnerability stems from improper input validation, classified under CWE-20, which allows an authenticated user with adjacent access to escalate privileges within the system. Intel Manageability Commander is a management tool used to remotely control and manage Intel-based systems, often deployed in enterprise environments for system administration tasks. The flaw enables a user who already has some level of authenticated access but limited privileges to leverage the improper input validation to gain higher privileges, potentially full administrative control. The attack vector is adjacent network access (AV:A), meaning the attacker must be on the same local network or have network proximity. The vulnerability does not require user interaction (UI:N) but does require low privileges (PR:L) to exploit. The scope is unchanged (S:U), but the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), indicating that successful exploitation can lead to complete system compromise, data breaches, and disruption of services. Although no known exploits are reported in the wild, the CVSS score of 8.0 reflects the significant risk posed by this vulnerability if exploited. The vulnerability was published on May 12, 2022, and affects systems running Intel Manageability Commander before version 2.2. Since this tool is used for system management, the vulnerability could be leveraged to undermine enterprise security controls and gain unauthorized control over critical infrastructure components.

For European organizations, the impact of CVE-2021-0126 could be substantial, especially for enterprises and public sector entities relying on Intel Manageability Commander for remote system management. Exploitation could allow attackers to escalate privileges and gain administrative control over managed devices, potentially leading to unauthorized access to sensitive data, disruption of IT operations, and lateral movement within corporate networks. This is particularly critical for sectors with stringent data protection requirements such as finance, healthcare, and government institutions across Europe. The vulnerability could also undermine compliance with regulations like GDPR if personal data confidentiality and integrity are compromised. Furthermore, the need for adjacent network access means that attackers could exploit this vulnerability from within the corporate network or through compromised internal segments, increasing the risk of insider threats or attacks originating from compromised devices within the network perimeter.

To mitigate CVE-2021-0126, European organizations should prioritize upgrading Intel Manageability Commander to version 2.2 or later, where the vulnerability has been addressed. In environments where immediate patching is not feasible, network segmentation should be enforced to restrict access to management interfaces only to trusted administrators and systems, minimizing the risk of adjacent network exploitation. Implement strict access controls and monitoring on the management network to detect and prevent unauthorized access attempts. Employ network intrusion detection systems (NIDS) to identify anomalous behavior related to privilege escalation attempts. Additionally, organizations should conduct regular audits of user privileges and ensure that only necessary personnel have authenticated access to management tools. Where possible, leverage multi-factor authentication (MFA) for accessing management consoles to add an additional security layer. Finally, maintain up-to-date asset inventories to quickly identify and remediate vulnerable instances of Intel Manageability Commander.
