CVE-2024-30062 is a high-severity use-after-free vulnerability (CWE-416) affecting Microsoft Windows Server 2019, specifically version 10.0.17763.0. The vulnerability exists within the Windows Standards-Based Storage Management Service, which is responsible for managing storage devices and related operations. A use-after-free flaw occurs when a program continues to use a pointer after the memory it points to has been freed, potentially leading to arbitrary code execution, memory corruption, or system crashes. In this case, the vulnerability allows an attacker to execute remote code on the affected system. The CVSS 3.1 base score is 7.8, indicating a high severity level. The attack vector is local (AV:L), meaning the attacker must have local access to the system, but no privileges are required (PR:N). User interaction is required (UI:R), implying that exploitation depends on some user action, such as opening a malicious file or interacting with a crafted interface. The vulnerability impacts confidentiality, integrity, and availability, as successful exploitation could lead to full system compromise. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability was reserved in March 2024 and published in June 2024, indicating recent discovery and disclosure. Given the critical role of Windows Server 2019 in enterprise environments, this vulnerability poses a significant risk if exploited, especially in environments where local access can be obtained or where users might be tricked into interaction.

For European organizations, this vulnerability presents a substantial risk, particularly for enterprises relying on Windows Server 2019 for critical infrastructure, storage management, and data center operations. Exploitation could lead to unauthorized remote code execution, allowing attackers to gain control over affected servers, potentially leading to data breaches, disruption of services, and lateral movement within networks. The confidentiality of sensitive data could be compromised, integrity of stored information altered, and availability of storage services disrupted. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are especially vulnerable due to their reliance on secure and stable server environments. The requirement for local access and user interaction somewhat limits the attack surface but does not eliminate risk, especially in environments with many users or where attackers have insider access or can trick users into interaction. The absence of known exploits in the wild provides a window for mitigation, but the high severity score necessitates prompt action to prevent potential exploitation.

European organizations should prioritize the following specific mitigation steps: 1) Immediately inventory and identify all Windows Server 2019 systems running version 10.0.17763.0 to assess exposure. 2) Monitor official Microsoft channels closely for the release of security patches addressing CVE-2024-30062 and apply them promptly upon availability. 3) Implement strict access controls to limit local access to Windows Server 2019 machines, including enforcing least privilege principles and restricting administrative rights. 4) Educate users about the risks of interacting with untrusted content or interfaces that could trigger the vulnerability, reducing the likelihood of successful user interaction exploitation. 5) Employ endpoint detection and response (EDR) solutions to monitor for suspicious activities indicative of exploitation attempts, such as unusual memory usage or process behavior related to storage management services. 6) Consider network segmentation to isolate critical servers and reduce the risk of lateral movement if compromise occurs. 7) Regularly audit and harden storage management configurations to minimize unnecessary exposure. These targeted actions go beyond generic patching advice by emphasizing access restriction, user awareness, and proactive monitoring specific to the vulnerability's characteristics.
