Microsoft Exchange Server - Patch Now! - WST

On Tuesday, March 2, 2021, Microsoft released out-of-band advisories detailing serious vulnerabilities in Microsoft Exchange Server that are currently being exploited in the wild. These vulnerabilities only affect the on-premises version of Exchange, so if you are using Exchange Online through Microsoft 365 (formerly Office 365) you do not need to take action. If you are running Exchange Server on-premises, it is highly recommended that you patch your servers as soon as possible. More detailed information can be found at the Microsoft blog post here: https://www.microsoft.com/en-us/security/blog/2021/03/02/hafnium-targeting-exchange-servers/ and the US-CERT CISA alert here: https://www.cisa.gov/news-events/cybersecurity-advisories/aa21-062a
