CVE-2025-48000: CWE-416: Use After Free in Microsoft Windows 10 Version 1809
Use after free in Windows Connected Devices Platform Service allows an authorized attacker to elevate privileges locally.
AI Analysis
Technical Summary
CVE-2025-48000 is a high-severity use-after-free vulnerability identified in the Windows Connected Devices Platform Service on Microsoft Windows 10 Version 1809 (build 10.0.17763.0). This vulnerability arises from improper handling of memory where the service attempts to use memory after it has been freed, leading to undefined behavior. Exploiting this flaw allows an authorized local attacker—meaning one with some level of access to the system but not necessarily administrative privileges—to elevate their privileges. The attacker can leverage this to gain higher-level permissions, potentially full administrative control over the affected system. The vulnerability does not require user interaction and has low attack complexity, indicating that exploitation is relatively straightforward once local access is obtained. The CVSS v3.1 base score of 7.8 reflects the significant impact on confidentiality, integrity, and availability, as successful exploitation can lead to complete system compromise. Although no known exploits are currently reported in the wild, the vulnerability's nature and severity make it a critical concern for organizations still running this older Windows 10 version. The lack of published patches at this time increases the urgency for mitigation and risk management.
Potential Impact
For European organizations, the impact of CVE-2025-48000 can be substantial, especially in environments where Windows 10 Version 1809 remains in use, such as legacy systems or specialized industrial setups. Successful exploitation could allow attackers to bypass existing security controls and gain administrative privileges, leading to unauthorized access to sensitive data, disruption of critical services, and potential lateral movement within corporate networks. This could result in data breaches, intellectual property theft, operational downtime, and compliance violations under regulations like GDPR. The vulnerability's local attack vector means that insider threats or attackers who have gained initial footholds through other means could escalate privileges rapidly. Given the high confidentiality, integrity, and availability impacts, organizations in sectors such as finance, healthcare, manufacturing, and government are particularly at risk, as these sectors often rely on legacy systems and handle sensitive information.
Mitigation Recommendations
To mitigate this vulnerability effectively, European organizations should prioritize upgrading affected systems to a supported and patched version of Windows 10 or later. If immediate upgrades are not feasible, organizations should implement strict access controls to limit local user privileges and restrict access to systems running Windows 10 Version 1809. Employing application whitelisting and endpoint detection and response (EDR) solutions can help detect and prevent exploitation attempts. Network segmentation should be enforced to isolate legacy systems from critical infrastructure and sensitive data repositories. Regular auditing of user accounts and privileges will reduce the risk of unauthorized local access. Additionally, organizations should monitor for unusual local privilege escalation activities and prepare incident response plans tailored to this vulnerability. Since no patches are currently available, applying virtual patching via host-based intrusion prevention systems (HIPS) or deploying custom rules to detect exploitation patterns can provide temporary protection.
