The affected versions include Exchange Servers 2010, 2013, 2016 and 2019. In mid-April, we took a look at our data to see how quickly users are updating this software to the new releases. Unfortunately, we&#8217;re not seeing as much progress as we anticipated regarding the Microsoft Exchange vulnerable release. Remarkably, our data shows that more than <strong>50% of devices<\/strong> are still running <strong>vulnerable versions<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What Component <strong>is Vulnerable?<\/strong><\/h3>\n\n\n\n<p>The vulnerable MS Exchange component is part of the <strong>network<\/strong> stack. The set of possible attackers extends beyond those normally listed to the <strong>entire Internet<\/strong>. This type of <strong>cyber-vulnerability<\/strong> is often termed &#8220;<em>remotely exploitable<\/em>&#8220;.  This makes a cyber attack at the protocol level possible across one or more routers. To ensure greater cyber-protection, users should check to see that they aren&#8217;t running vulnerable releases of the program.<\/p>\n\n\n\n<p><strong>Security<\/strong> is proposedly one of the main benefits of using Exchange Server. It allows users to link their email, contacts, and calendars from Windows applications on their PC to browsers, and to their mobile devices. IT administrators should prioritize installing updates to help protect users&#8217; confidentiality. The vulnerability patch will help prevent a loss of confidentiality which could result in data being divulged to an attacker. <\/p>\n\n\n\n<p><strong>PC Matic<\/strong> is confident that its customers are secure but stresses that any vulnerable software should be patched immediately as a best practice. As new releases of Microsoft Exchange come out, our team of cyber security specialists will continue to monitor vulnerabilities.<\/p>\n\n\n\n<p>Visit the <a href=\"https:\/\/support.microsoft.com\/en-us\/topic\/description-of-the-security-update-for-microsoft-exchange-server-2019-2016-and-2013-march-2-2021-kb5000871-9800a6bb-0a21-4ee7-b9da-fa85b3e1d23b\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Microsoft Download Center<\/strong><\/a> to download new releases. <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Microsoft Exchange New Release is Vulnerable.
