CVE-2025-54108 is a race condition vulnerability classified under CWE-362, found in the Capability Access Management Service (camsvc) component of Microsoft Windows Server 2025 Server Core installations (version 10.0.26100.0). The flaw arises from improper synchronization when multiple concurrent threads or processes access shared resources, leading to a race condition. This condition can be exploited by an attacker with local, low-privilege access to the system to elevate their privileges to higher levels, potentially SYSTEM or administrative privileges. The vulnerability does not require user interaction but does require the attacker to have some level of authorized local access. The CVSS 3.1 base score is 7.0, reflecting high severity due to the high impact on confidentiality, integrity, and availability if exploited, though the attack complexity is high and requires local privileges. No public exploits or patches are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. The race condition could allow attackers to bypass security controls, manipulate access tokens, or interfere with capability management, resulting in unauthorized access and control over the affected server. This vulnerability is particularly critical in server environments where Windows Server 2025 Server Core is deployed, as it could undermine the security posture of enterprise and critical infrastructure systems.

For European organizations, the impact of CVE-2025-54108 could be significant, especially for those relying on Windows Server 2025 Server Core installations in critical infrastructure, financial services, healthcare, and government sectors. Successful exploitation would allow attackers with local access to escalate privileges, potentially gaining administrative control over servers. This could lead to unauthorized data access, manipulation, or destruction, disruption of services, and lateral movement within networks. The confidentiality, integrity, and availability of sensitive data and critical services could be severely compromised. Given the high adoption rate of Microsoft server products across Europe, the vulnerability poses a substantial risk to enterprise environments. Additionally, organizations with remote or delegated administrative access might face increased exposure if attackers gain footholds through less privileged accounts. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits after public disclosure.

1. Apply official patches or updates from Microsoft immediately once they become available to address this vulnerability. 2. Until patches are released, restrict local access to Windows Server 2025 Server Core systems to trusted personnel only, minimizing the attack surface. 3. Implement strict access controls and monitoring on accounts with local privileges to detect unusual or unauthorized privilege escalation attempts. 4. Employ endpoint detection and response (EDR) solutions capable of identifying race condition exploitation patterns or suspicious behavior related to camsvc. 5. Use application whitelisting and privilege management tools to limit the execution of unauthorized code and reduce the risk of privilege escalation. 6. Regularly audit and review server configurations and logs for signs of exploitation or attempted attacks. 7. Educate system administrators and security teams about this specific vulnerability and the importance of timely patching and monitoring. 8. Consider network segmentation to isolate critical servers and reduce the impact of a potential compromise.
