This month we got patches for 66 vulnerabilities. Of these, 5 are critical, and 2 are already being exploited, according to Microsoft.

One of the exploited vulnerabilities is a Microsoft Streaming Service Proxy Elevation of Privilege Vulnerability (CVE-2023-36802). According to the advisory, an attacker who successfully exploited this vulnerability could gain SYSTEM privileges. The CVSS for this vulnerability is 6.8.

The second one is a Microsoft Word Information Disclosure Vulnerability (CVE-2023-36761). According to the advisory, the Preview Pane is an attack vector and exploiting this vulnerability could allow the disclosure of NTLM hashes. 

Regarding critical vulnerabilities, one of them is a Remote Code Execution (RCE) vulnerability on Internet Connection Sharing (ICS) (CVE-2023-38148). According to the advisory, an unauthorized attacker could exploit this Internet Connection Sharing (ICS) vulnerability by sending a specially crafted network packet to the Internet Connection Sharing (ICS) Service. This vulnerability requires no user interaction and no privileges. The CVSS is 8.8 -  the highest for this month.

The second highest CVSS this month is associated to a RCE affecting Visual Studio (CVE-2023-36793). To exploit this vulnerability an attacker would have to convince a user to open a maliciously crafted package file in Visual Studio. The CVSS is 7.8.
