CVE-2024-30000 is a security vulnerability identified in the Windows Mobile Broadband Driver component of Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability is classified under CWE-190, which pertains to integer overflow or wraparound errors. Specifically, this flaw arises when the driver improperly handles integer values, allowing an attacker to cause an overflow or wraparound condition. This can lead to memory corruption, potentially enabling remote code execution (RCE) without requiring any user interaction or privileges. The CVSS 3.1 base score is 6.8, indicating a medium severity level. The attack vector is remote and requires low attack complexity, with no privileges or user interaction needed, making exploitation feasible over a network. However, no known exploits have been reported in the wild as of the publication date (May 14, 2024). The vulnerability affects only Windows 10 Version 1809, which is an older release of Windows 10, and specifically the Mobile Broadband Driver, a component used to manage cellular network connectivity on devices. Successful exploitation could allow an attacker to execute arbitrary code remotely, compromising confidentiality, integrity, and availability of the affected system. The lack of a published patch at this time increases the risk for unpatched systems. Given the technical nature of the flaw, exploitation would likely require crafted network packets targeting the Mobile Broadband Driver interface.

For European organizations, the impact of this vulnerability could be significant, particularly for those relying on Windows 10 Version 1809 devices with Mobile Broadband capabilities. Sectors such as telecommunications, mobile workforce environments, and critical infrastructure operators using cellular connectivity for remote access or IoT devices could be at risk. Exploitation could lead to unauthorized remote code execution, enabling attackers to gain control over affected systems, steal sensitive data, disrupt operations, or pivot within networks. Given that Windows 10 Version 1809 is an older version, organizations that have not upgraded or patched legacy systems remain vulnerable. The compromise of devices with cellular connectivity could also facilitate lateral movement into corporate networks, increasing the potential for widespread impact. Although no exploits are currently known in the wild, the medium severity rating and ease of remote exploitation without user interaction warrant proactive mitigation to prevent potential targeted attacks. Confidentiality, integrity, and availability of critical systems could be compromised, affecting business continuity and regulatory compliance, especially under stringent European data protection laws.

1. Immediate assessment and inventory of all devices running Windows 10 Version 1809 with Mobile Broadband capabilities within the organization. 2. Prioritize upgrading affected systems to a supported and patched version of Windows 10 or later, as Windows 10 Version 1809 is out of mainstream support and may not receive official patches. 3. If upgrading is not immediately feasible, implement network-level controls to restrict or monitor traffic to and from Mobile Broadband interfaces, including segmentation and firewall rules to limit exposure. 4. Employ endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts targeting the Mobile Broadband Driver. 5. Regularly review and apply any security advisories or patches released by Microsoft related to this vulnerability. 6. Educate IT staff on the specific risks associated with legacy Windows versions and the importance of timely patch management. 7. For organizations using cellular connectivity for critical operations, consider alternative secure communication channels or VPNs to reduce direct exposure of vulnerable drivers. 8. Collaborate with mobile network providers to understand and mitigate risks associated with cellular network attacks that could exploit this vulnerability.
