August has brought 114 vulnerabilities targeted to Windows OS, browsers and Microsoft Office. This month there are actually patches to fix rather remarkable vulnerabilities.

At first there is a critical vulnerability CVE-2020-1472 targeted to Windows Server domain controllers. The vulnerability has the highest scoring of 10.0 in CVSS rating. In addition to that there is a vulnerability which has been publicly disclosed (CVE-2020-1464). The very same vulnerability also has been exploited in wild. There is also a second vulnerability which has been exploited in wild (CVE-2020-1380).

The impact and scoring of these and other vulnerabilities can be explored with Common Vulnerability Scoring System Calculator. Microsoft posts CVSS-calculator (maintained by National Vulnerability Database) links for all the vulnerabilities in their vulnerability articles. More thorough information of the vulnerabilities can be found from Microsoft’s MSRC-portal.

However, Centero recommends to test the updates thoroughly before deploying them to production endpoints. In addition to this, all the known issues should be read through and reflected to own environment.

Microsoft maintains a list of Windows updates and their known issues on the following pages.

With Centero Software Manager Cloud and CSM Cloud for Servers it’s possible to deploy these updates into your environment and even on remote computers by the configuration you have defined.
