Microsoft September 2020 Patch Tuesday

This month we got patches for 129 vulnerabilities. Of these, 23 are critical and none of them was previously disclosed or is being exploited according to Microsoft.

Amongst the critical ones, there is a remote code execution (RCE) vulnerability in Microsoft SharePoint (CVE-2020-1210) with a CVSS score of 9.9 (the highest this month). The vulnerability exists when the software fails to check the source markup of an application package. To exploit this vulnerability, an attacker has to upload a specially crafted SharePoint application package to a vulnerable SharePoint.

There is also an RCE in Microsoft Exchange (CVE-2020-16875), with a CVSS score of 9.1. To exploit this vulnerability, an attacker has to send a specially crafted e-mail to a vulnerable Exchange Server. An attacker who successfully exploits this vulnerability could run arbitrary code in the context of System user.

A third vulnerability worth mentioning is an RCE affecting Active Directory (CVE-2020-0761) when integrated with DNS (ADIDNS). An authenticated attacker could run arbitrary code in the context of Local System account if successfully exploits this vulnerability. To exploit the vulnerability, an authenticated attacker could send malicious requests to an Active Directory integrated DNS (ADIDNS) server. The CVSS score for this vulnerability is 8.8.
