Microsoft released its monthly (September’s) security update, Patch Tuesday, disclosing 63 vulnerabilities across the company’s hardware and software line, using their vulnerability management tools. Microsoft September 2022 Patch Tuesday security update is observed to have a sharp decline from last month’s number of issues disclosed by Microsoft.
Microsoft’s Security Update addresses five critical vulnerabilities which tend to allow Remote Code Execution which is ten fewer than were included in last month’s patch Tuesday. There are two moderate-severity vulnerabilities in this very release and one low-security issue. It’s important to use a vulnerability management tool for these. The remaining are classified as “Important,” therefore those have Denial of Service (DOS), Elevation of Privilege, Information Disclosure, Remote Code Execution, and Security Feature Bypass per the advisory. A compiled list is available for reference below.
Patch Tuesday fixes 2 Zero-Day vulnerabilities, with one being designated as actively exploited* (CVE-2022-37969*, CVE-2022-23960) is said to be of Privilege Escalation and Cache Speculation Restriction, respectively. Along with this, Microsoft has speedily quashed 16 Microsoft Edge (Chromium Based)Vulnerabilities, of which one has been addressed as a Remote Code Execution (RCE) (CVE-2022-38012). Therefore the same was updated from September 1st to 3rd, 2022
CVE-2022-37969 | Windows Common Log File System Driver Elevation Of Privilege Vulnerability
This vulnerability has a CVSSv3.1 score of 7.8. An attacker should have access and the ability to run code on the target system. Common social engineering delivery methods can be used to initiate attacks for bugs of this nature, such as sending specially crafted documents and convincing users to click on the document or link. Hence, an attacker who can successfully exploit this could gain SYSTEM privileges. Therefore, this vulnerability is being actively exploited as per the Exploit-ability Assessment by Microsoft.
CVE-2022-23960 | Cache Speculation Restriction Vulnerability
This vulnerability has a CVSSv3.1 score of 5.6.CVE-2022-23960 is regarding a vulnerability known as Specter-BHB. An attacker can in fact trick users into downloading and opening a specially crafted presentation file. Hence, this CVE affects Windows 11 (ARM64-based system).
In addition Please see Spectre-BHB on arm Developer for more information.
Critical Vulnerabilities (Resolved by Microsoft’s September Patch Tuesday)
In this September 2022 Patch Tuesday, Microsoft has furthermore addressed five critical vulnerabilities.
CVE-2022-37956, CVE-2022-37957, and CVE-2022-37964 | Windows Kernel Elevation Privilege Vulnerability
CVE-2022-37956, CVE-2022-37957, and CVE-2022-37964 are clubbed under the Elevation of Privilege, which is supposed to affect the Windows Kernel. All three vulnerabilities have received a CVSSv3 score of 7.8. Microsoft advisory says a successful attack against this component will reward an attacker for gaining SYSTEM privileges.
As per the Exploit-ability by Microsoft, only CVE-2022-37957 has been designated as “Excitability More Likely.”
CVE-2022-34721 and CVE-2022-34722 | Windows Internet Key Exchange (IKE) Remote Execution Vulnerability.
CVE-2022-34721 and CVE-2022-34722 together are RCE vulnerabilities in the Windows IKE Protocol. Both have been given a CVSSv3 score of 9.8, and the Exploitability Assessment by Microsoft is “Less Likely.” An unauthenticated attacker could send a specially crafted IP packet to a target machine running Windows and IPSec enabled, hence enabling remote code execution exploitation. All Windows Servers are affected because they accept both V1 and V2 packets.
CVE-2022-37958 | Updated: New Flaw Discovered (Resolved by Patch Tuesday).
As of December 21, 2022, CVE-2022-37958 severity has elevated from important to critical.
A new flaw has been discovered, which works like Eternal Blue and hence could be exploited remotely without any authentication required. Reportedly the bug is “wormable,” which means it can self-replicate and laterally move to hit other vulnerable systems in the network and hence might arise a new problem.
The flaw in CVE-2022-37958 is not limited to the SPNEGO Mechanism, which resides in the Server Message Block (SMB) protocol. It can also affect RDP, SMTP, and HTTP.
Microsoft fixed the previously existing bug in September 2022 with its Patch Tuesday rollout, which also fixes this new flaw.
