Key Vulnerabilities
Skype for Business privilege escalation vulnerability (CVS 2023-41763):
Skype for Business has a privilege escalation vulnerability, which allows remote attackers without authentication to make specialized network calls to the target Skype for Business server, potentially causing HTTP requests sent to arbitrary addresses to be parsed, revealing the IP address and port number to the attacker. Attackers who successfully exploit this vulnerability can view sensitive information, and in some cases, the exposed sensitive information can provide access to the internal network. The vulnerability has been publicly disclosed and has been exploited in the wild.

Microsoft WordPad Information Disclosure Vulnerability (CVS 2023-36563):
There is an information leakage vulnerability in Microsoft WordPad, which allows remote attackers who do not require authentication to exploit the vulnerability by running a crafted application or inducing local users to open malicious files after logging into the system. Successful exploitation of this vulnerability can result in NTLM hash leakage. The vulnerability has been publicly disclosed and has been exploited in the wild, with a CVSS score of 6.5.

MITRE: CVE-2023-44487-HTTP/2 Quick Reset Attack
Microsoft has released mitigation measures for DDoS attacks on HTTP/2, known as the “HTTP/2 Rapid Reset”. This attack abuses the HTTP/2 stream cancellation function to continuously send and cancel requests, causing the target server/application to run out of resources and cause a denial of service. This vulnerability has been widely exploited since August.

Windows Layer 2 Tunneling Protocol Remote Code Execution Vulnerability (CVE-2023-41770/CVE-2023-41765/CVE-2023-41767/CVE-2023-38166/CVE-2023-41774/CVE-2023-41773/CVE-2023-41771/CVE-2023-41769/CVE-2023-41768):
Unauthenticated remote attackers can cause remote code execution on the RAS server computer by sending crafted protocol messages to the Routing and Remote Access Service (RRAS) server. Successful exploitation of this vulnerability requires the attacker to win competitive conditions. The CVSS score is 8.1.

Microsoft Message Queuing Remote Code Execution Vulnerability (CVS 2023-35349):
There is a remote code execution vulnerability in Microsoft Message Queuing, which allows unauthenticated remote attackers to remotely execute code on the target server when the Message Queuing service is enabled. The CVSS score is 9.8.
Official announcement link:
https://msrc.microsoft.com/update-guide/en-US/advisory/CVE-2023-35349
Microsoft Message Queuing Remote Code Execution Vulnerability (CVS 2023-36697):
There is a remote code execution vulnerability in Microsoft Message Queuing, which allows authenticated domain users to remotely execute code on the target server. However, attackers need to induce the victim user to connect to a malicious server or disrupt the legitimate MSMQ server host and make it run as a malicious server. The CVSS score is 6.8.
