Multiple Critical Vulnerabilities Announced by Microsoft

1 min read

The Threat

During the regularly scheduled Microsoft patch release on January 14, 2019, multiple critical vulnerabilities were released that require immediate action. CVE-2020-0601 is a CryptoAPI spoofing vulnerability that, if exploited, could be used to make a malicious program appear as a legitimately signed Microsoft program, bypassing standard security measures [1]. CVE-2020-0609 and CVE-2020-0610 are Remote Desktop Gateway vulnerabilities that could allow remote and unauthenticated threat actors to execute code on vulnerable Windows servers [2]. To avoid being impacted, it is highly recommended to apply the Microsoft patches as soon as possible.
