CVE-2024-30082 is a high-severity Use After Free (CWE-416) vulnerability affecting Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability exists within the Win32k component, a core part of the Windows graphical subsystem responsible for window management and user interface rendering. 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 memory corruption, arbitrary code execution, or system crashes. In this case, the flaw allows an attacker with limited privileges (local privileges with low complexity) to elevate their privileges to higher levels without requiring user interaction. The CVSS v3.1 base score of 7.8 reflects the significant impact on confidentiality, integrity, and availability, with the attack vector being local (AV:L), low attack complexity (AC:L), requiring privileges (PR:L), and no user interaction (UI:N). The scope remains unchanged (S:U), meaning the vulnerability affects the same security scope. Exploitation could allow an attacker to execute arbitrary code in kernel mode, potentially gaining full control over the affected system. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a critical candidate for targeted attacks, especially in environments where Windows 10 Version 1809 is still in use. The absence of patch links suggests that a fix may not yet be publicly available, increasing the urgency for organizations to monitor updates and apply patches promptly once released.

For European organizations, the impact of CVE-2024-30082 is significant, particularly for those still operating legacy systems such as Windows 10 Version 1809. Successful exploitation could lead to full system compromise, allowing attackers to bypass security controls, access sensitive data, disrupt operations, or deploy ransomware and other malware. Critical infrastructure, government agencies, financial institutions, and enterprises with high-value intellectual property are at heightened risk. The elevation of privilege vulnerability can be leveraged to move laterally within networks, escalate access, and maintain persistence. Given the local attack vector, initial access would require some foothold on the system, such as through phishing or insider threat, but once achieved, the attacker can gain kernel-level privileges. This undermines endpoint security and complicates incident response. The lack of user interaction requirement increases the threat as automated or stealthy exploitation is feasible. European organizations with compliance obligations under GDPR and other regulations must consider the confidentiality and integrity risks posed by this vulnerability, as data breaches resulting from exploitation could lead to regulatory penalties and reputational damage.

1. Immediate inventory and identification of all systems running Windows 10 Version 1809 (build 10.0.17763.0) within the organization. 2. Monitor Microsoft security advisories closely for the release of an official patch addressing CVE-2024-30082 and prioritize rapid deployment once available. 3. Until patches are available, implement strict access controls to limit local user privileges, minimizing the number of users with local login rights on vulnerable systems. 4. Employ application whitelisting and endpoint detection and response (EDR) solutions to detect anomalous behavior indicative of exploitation attempts targeting Win32k. 5. Conduct regular vulnerability scanning and penetration testing focusing on privilege escalation vectors to identify potential exploitation paths. 6. Enforce network segmentation to contain potential lateral movement in case of compromise. 7. Educate users about phishing and social engineering risks to reduce initial foothold opportunities for attackers. 8. Consider upgrading affected systems to a supported and patched Windows version if feasible, as Windows 10 Version 1809 is an older release with limited support lifecycle. 9. Implement strict logging and monitoring of security events related to privilege escalation attempts to enable rapid detection and response.
