Microsoft has released patches for 65 vulnerabilities, of which 6 are actively exploited Zero-Day. Among the 6 Zero-day, CVE-2022-41091 vulnerability is publicly disclosed. Eleven of the 65 vulnerabilities fixed in this security update are classified as ‘Critical’ as they allow privilege elevation, spoofing, or remote code execution, and the rest as ‘Important’.
The 6 Zero-Day vulnerabilities include Microsoft Exchange Server (CVE-2022-41082, CVE-2022-41040), Windows CNG Key Isolation Service (CVE-2022-41125), Windows Print Spooler (CVE-2022-41073), Windows Scripting Languages (CVE-2022-41128), Windows Mark of the Web Security (CVE-2022-41091).
Patch Tuesday November 2022 fixed zero-day vulnerabilities like:
CVE-2022-41082, CVE-2022-41040 – Microsoft Exchange Server Remote Code Execution and Elevation of Privilege Vulnerability. An authenticated attacker could attempt to trigger malicious code in the context of the server’s account through a network call. These vulnerabilities were disclosed in late September by Vietnamese cybersecurity firm GTSC, who first spotted the flaws used in attacks. Successful exploitation of the vulnerability could allow authenticated attackers to perform remote code execution with elevated privileges.
CVE-2022-41125 – Windows CNG Key Isolation Service Elevation of Privilege Vulnerability. Successful exploitation of this vulnerability could allow the attacker to gain SYSTEM privileges.
CVE-2022-41073 – Windows Print Spooler Elevation of Privilege Vulnerability. Successful exploitation of this vulnerability could allow the attacker to gain SYSTEM privileges.
CVE-2022-41128 – Windows Scripting Languages Remote Code Execution Vulnerability. The JScript9 scripting language, a component of the Scripting Language, is vulnerable to this flaw. The victim must interact with the attacker for it to succeed. Successful exploitation of the vulnerability could allow attackers to perform remote code execution.
CVE-2022-41091 – Windows Mark of the Web Security Feature Bypass Vulnerability. The vulnerability is being exploited in the wild and exploit of the vulnerability is publicly available. A malicious actor could craft a file that could bypass MoTW “resulting in a limited loss of integrity and availability of security features such as Protected View.”
