Technical Analysis

CVE-2025-47976 is a high-severity use-after-free vulnerability (CWE-416) found in the Windows SSDP (Simple Service Discovery Protocol) Service on Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The vulnerability allows an authorized local attacker to elevate privileges by exploiting improper memory management within the SSDP service. Specifically, the use-after-free condition occurs when the service accesses memory after it has been freed, potentially enabling an attacker to execute arbitrary code with elevated privileges or cause a denial of service. The vulnerability requires local access with limited privileges (PR:L) and does not require user interaction (UI:N). The attack complexity is low (AC:L), meaning exploitation is feasible without specialized conditions. The vulnerability impacts confidentiality, integrity, and availability (all rated high), indicating that successful exploitation could lead to full system compromise. The CVSS 3.1 base score is 7.8, reflecting the significant risk posed by this flaw. No known exploits are currently reported in the wild, and no patches or mitigation links have been published yet. Given the nature of the vulnerability in a core Windows service, exploitation could allow attackers to bypass security controls and gain administrative rights, enabling further malicious activities such as installing persistent malware, accessing sensitive data, or disrupting system operations.

Potential Impact

For European organizations, this vulnerability poses a substantial risk, especially for enterprises and government agencies still operating Windows 10 Version 1809 systems. Privilege escalation vulnerabilities enable attackers who have limited access—such as through compromised user accounts or insider threats—to gain full control over affected machines. This can lead to lateral movement within networks, data breaches involving personal and corporate information, and disruption of critical services. The impact is particularly severe for sectors with sensitive data, including finance, healthcare, and public administration. Additionally, organizations bound by GDPR must consider the regulatory consequences of data breaches resulting from exploitation. Since Windows 10 Version 1809 is an older release, some organizations may not have upgraded due to compatibility or operational constraints, increasing their exposure. The lack of known exploits in the wild provides a window for proactive mitigation, but the vulnerability's low attack complexity and high impact make it a priority for remediation to prevent potential targeted attacks.

Mitigation Recommendations

Given the absence of an official patch at this time, European organizations should implement the following specific mitigations: 1) Identify and inventory all systems running Windows 10 Version 1809 to assess exposure. 2) Apply strict access controls and limit local user privileges to reduce the pool of users who can exploit this vulnerability. 3) Disable or restrict the Windows SSDP Service where it is not required, as this reduces the attack surface. 4) Employ application whitelisting and endpoint detection and response (EDR) solutions to monitor for suspicious activity indicative of privilege escalation attempts. 5) Enforce network segmentation to contain potential lateral movement if a system is compromised. 6) Prepare for rapid deployment of patches once Microsoft releases an official fix by establishing robust patch management processes. 7) Conduct user awareness training to reduce the risk of initial compromise that could lead to local access. These targeted actions go beyond generic advice by focusing on reducing the attack vector and preparing for imminent patching.
