Description

Microsoft recently reported two Important-rated elevation-of-privilege vulnerabilities in the Windows Remote Access Connection Manager. Disclosed on December 9, 2025, the issues can be exploited by authenticated local users with low-level privileges to gain higher permissions on affected systems. Both vulnerabilities target the same Windows component and arise from weaknesses in access control enforcement and memory handling. Exploitation does not require any user interaction, but attackers must already have local access to the system. The first flaw, identified as CVE-2025-62474, is caused by improper access controls that allow security restrictions to be bypassed, enabling attackers to elevate their privileges. The second issue, CVE-2025-62472, originates from memory management errors, specifically the use of uninitialized resources and use-after-free conditions. Although the underlying causes differ, both vulnerabilities can lead to similar outcomes, potentially allowing attackers to gain extensive control over the affected system. Each vulnerability carries a CVSS v3.1 base score of 7.8, reflecting a high potential impact despite the local-only attack vector. The low attack complexity and minimal privileges required mean that exploitation could be achievable by attackers with relatively basic technical skills. Given the risk of full system compromise, organizations are strongly advised to prioritize patching once updates are available, closely follow Microsoft’s official security advisories, and review internal access controls to limit unnecessary elevated privileges.
