CVE-2025-60715 is a heap-based buffer overflow vulnerability identified in the Windows Routing and Remote Access Service (RRAS) component of Microsoft Windows 10 Version 1809 (build 10.0.17763.0). The flaw arises from improper handling of data in heap memory, which can be exploited by an attacker with authorized network access to RRAS. This vulnerability allows the attacker to execute arbitrary code remotely, potentially leading to full system compromise including elevated privileges, data theft, or service disruption. The attack vector is network-based (AV:N), requiring low attack complexity (AC:L), and privileges at the level of an authorized user (PR:L). User interaction is required (UI:R), and the scope remains unchanged (S:U). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no public exploits have been reported yet, the severity and nature of the vulnerability make it a significant risk. RRAS is commonly used in enterprise environments for VPN and routing services, increasing the attack surface. The vulnerability was reserved on 2025-09-26 and published on 2025-11-11, with no patches currently available, emphasizing the need for proactive mitigation.

For European organizations, this vulnerability poses a serious risk especially to enterprises and critical infrastructure sectors that rely on Windows 10 Version 1809 with RRAS enabled for remote access and routing services. Successful exploitation could lead to unauthorized remote code execution, enabling attackers to gain control over affected systems, steal sensitive data, disrupt services, or move laterally within networks. This could impact confidentiality, integrity, and availability of critical systems. Given the network-based attack vector and low complexity, attackers could exploit this vulnerability to compromise corporate networks, potentially affecting sectors such as finance, healthcare, government, and industrial control systems. The lack of available patches increases exposure time, and the requirement for authorized access means insider threats or compromised credentials could facilitate attacks. The disruption of RRAS services could also degrade remote connectivity, impacting business continuity.

1. Immediately inventory and identify all systems running Windows 10 Version 1809 with RRAS enabled. 2. Disable RRAS on systems where it is not required to reduce the attack surface. 3. Restrict network access to RRAS services using firewall rules and network segmentation, limiting exposure to trusted networks and users only. 4. Implement strict access controls and monitor for unusual authentication attempts or network traffic targeting RRAS. 5. Enforce multi-factor authentication (MFA) for users authorized to access RRAS to reduce risk of credential compromise. 6. Apply patches promptly once Microsoft releases them for this vulnerability. 7. Use endpoint detection and response (EDR) tools to detect anomalous behavior indicative of exploitation attempts. 8. Conduct regular security awareness training to reduce risk of social engineering that could facilitate user interaction required for exploitation. 9. Maintain up-to-date backups and incident response plans to quickly recover from potential compromise.
