Microsoft addressed 74 vulnerabilities in their May 2022 Patch Tuesday Security Update. Three of them are zero-days, and one is being exploited in the wild.

The LSA Spoofing vulnerability (CVE-2022-26925) is actively exploited in the wild and allows an unauthenticated attacker to call a method on the LSARPC interface and compel the domain controller to use NTLM to authenticate the attacker. Successful exploitation of the second zero-day vulnerability(CVE-2022-22713) requires an attacker to win a race condition. The third zero-day vulnerability affects the Microsoft Integration Runtime services in the Magnitude Simba Amazon Redshift ODBC Driver.
