CVE-2025-47975 is a vulnerability classified as CWE-415 (Double Free) found in the Windows Simple Service Discovery Protocol (SSDP) Service on Windows 10 Version 1507 (build 10.0.10240.0). A double free occurs when a program attempts to free a region of memory twice, which can lead to memory corruption, crashes, or arbitrary code execution. In this case, the flaw allows an authorized local attacker to exploit the double free condition to elevate privileges on the affected system. The attacker must have local access and some level of privileges (low privileges) but does not require user interaction to trigger the vulnerability. The vulnerability impacts confidentiality, integrity, and availability by potentially allowing the attacker to execute code with elevated privileges, thereby compromising the system. The CVSS v3.1 score is 7.0 (high), reflecting the local attack vector, high attack complexity, required privileges, and the significant impact on system security. Currently, there are no known exploits in the wild, and no patches have been released, although the vulnerability was publicly disclosed on July 8, 2025. The SSDP service is typically used for network device discovery, and if not required, disabling it can reduce the attack surface. This vulnerability primarily affects legacy Windows 10 systems, which may still be in use in some environments due to compatibility or operational reasons.

For European organizations, the impact of CVE-2025-47975 can be significant, especially for those still operating legacy Windows 10 Version 1507 systems. Successful exploitation allows an attacker with local access to escalate privileges, potentially leading to full system compromise. This can result in unauthorized access to sensitive data, disruption of critical services, and the ability to deploy further malware or ransomware. Sectors such as government, healthcare, finance, and critical infrastructure are particularly at risk due to the sensitive nature of their data and services. The requirement for local access limits remote exploitation but insider threats or attackers who gain initial footholds via other means could leverage this vulnerability to deepen their control. The lack of available patches increases the window of exposure, making timely mitigation essential. Additionally, legacy systems may lack modern security controls, exacerbating the risk. The overall impact includes potential breaches of confidentiality, integrity, and availability, with possible regulatory and reputational consequences under European data protection laws.

1. Restrict local access to systems running Windows 10 Version 1507, especially limiting administrative and user privileges to trusted personnel only. 2. Disable the SSDP service on affected systems if it is not required for network device discovery or other operational needs, reducing the attack surface. 3. Implement strict endpoint security controls, including application whitelisting and behavior monitoring, to detect and prevent exploitation attempts. 4. Monitor system logs and security events for unusual activity related to the SSDP service or privilege escalation attempts. 5. Plan and prioritize upgrading legacy Windows 10 Version 1507 systems to supported versions with active security updates. 6. Apply any security patches or updates released by Microsoft as soon as they become available. 7. Employ network segmentation to isolate legacy systems from critical infrastructure and sensitive data environments. 8. Conduct regular security awareness training to reduce insider threat risks and improve detection of suspicious local activities.
