About CVE-2022-26925

CVE-2022-26925 is a security vulnerability in the Windows Local Security Authority (LSA) subsystem, which could allow attackers to bypass security measures and gain elevated privileges on a compromised system. The vulnerability has a CVSSv3 score of 5.9.

It was discovered in May 2022 and affects all Windows versions, including Windows 10 and Windows Server.

The vulnerability stems from how the Windows LSA subsystem handles application authentication requests. Specifically, the flaw exists in the way the LSA processes the authorization data in a Kerberos ticket. An attacker with network access to a target system could exploit the vulnerability by sending a specially crafted Kerberos ticket, which tricks the LSA into granting the attacker higher privileges than they are supposed to have.

An attacker who successfully exploits the vulnerability could potentially take control of the affected system, steal sensitive data, or execute malicious code. 

The issue was addressed with the May 2022 Patch Tuesday updates. It is recommended that all users of Windows systems, including both home and enterprise environments, apply the patch as soon as possible to ensure they are protected against this critical security flaw.
