Microsoft Patches LSASS Elevation of Privilege Vulnerabilities
Microsoft released security updates for two Local Security Authority Subsystem Service (LSASS) elevation of privilege flaws, tracked as CVE-2022-21884 and CVE-2022-30166. Both advisories identify weaknesses in the Windows component responsible for enforcing security policy and handling authentication, creating a path for attackers to gain higher privileges on affected systems.
The vulnerabilities were published through Microsoft's Security Update Guide and security advisory portal, indicating that organizations running impacted Windows environments should prioritize the relevant patches. Because LSASS operates with highly sensitive privileges, successful exploitation could allow an attacker with existing access to elevate permissions and strengthen control over a compromised host.
