This month we got patches for 88 vulnerabilities. Of these, 6 are critical, and 2 are already being exploited, according to Microsoft.

One of the exploited vulnerabilities is .NET and Visual Studio Denial of Service Vulnerability (CVE-2023-38180). The max severity for the vulnerability is important and the CVSS is 7.5.

The other exploited vulnerability is Microsoft Office Defense in Depth Update (ADV230003). According to the advisory this defense in depth update is not a vulnerability, but installing this update stops the attack chain leading to the Windows Search security feature bypass vulnerability (CVE-2023-36884). Microsoft recommends installing the Office updates discussed in this advisory as well as installing the Windows updates from August 2023.

Moving to critical vulnerabilities, there are Remote Code Execution (RCE) vulnerabilities affecting Microsoft Message Queuing (CVE-2023-35385, CVE-2023-36910, and CVE-2023-36911). According to the advisory, the Windows message queuing service, which is a Windows component, needs to be enabled for a system to be exploitable by this vulnerability. This feature can be added via the Control Panel. You can check to see if there is a service running named Message Queuing and TCP port 1801 is listening on the machine. Successful exploitation of this vulnerability could allow an unauthenticated attacker to remotely execute code on the target server. The attack complexity is low, no privileges and no user interaction are required. The CVSS for this vulnerability is 9.8.
