CVE-2024-20674
Microsoft
CVE-2024-20674 is a security feature bypass vulnerability in Windows Kerberos. This flaw allows an attacker to potentially bypass security measures, gaining unauthorized access or privileges. The SVRS score of 30 indicates a moderate level of risk, requiring monitoring but not immediate action.
Specifically, CVE-2024-20674 enables an attacker to circumvent intended security restrictions in the Windows Kerberos authentication system. Successful exploitation could lead to elevation of privilege or unauthorized actions within a network environment. While the CVSS score is 0, indicating no immediate impact without further conditions, the potential for bypass makes this vulnerability significant. Organizations should review and apply available patches to mitigate the risk. The impact stems from the core function of Kerberos in authenticating users and services, so bypassing it can have serious security implications. Failing to address this could permit malicious actors to compromise system integrity or user data.
