Elevation of Privilege Vulnerability in Windows Admin Center by Microsoft

CVE-2026-20965

What is CVE-2026-20965?

CVE-2026-20965 is an elevation of privilege vulnerability affecting Windows Admin Center, a management tool developed by Microsoft for managing Windows servers and configurations. This vulnerability arises from an improper verification of cryptographic signatures, which means that an authorized attacker could exploit this flaw to gain higher privileges than intended within the system. If successfully exploited, the attacker could perform unauthorized actions, potentially compromising the security framework of the organization. This could allow for manipulation of sensitive data or system configurations, leading to broader security implications for the affected environment.

Potential impact of CVE-2026-20965

1. Unauthorized Access: Attackers gaining elevated privileges could access sensitive information or execute malicious commands on the affected system, leading to data breaches or malicious alterations of system states.

2. Security Compromise: The potential for privilege escalation poses a serious risk, as it can enable attackers to undermine security controls and perform actions that are usually restricted to higher-level administrators.

3. Operational Disruption: The exploitation of this vulnerability could lead to significant operational risks, including downtime or degraded performance of services managed by Windows Admin Center, resulting in impacts on business continuity and service delivery.
