In the last Patch Tuesday of 2022, we got patches for 74 vulnerabilities. Of these, 7 are critical, 1 was previously disclosed, and 1 is already being exploited, according to Microsoft.

The exploited vulnerability is a Windows SmartScreen Security Feature Bypass Vulnerability (CVE-2022-44698). When you download a file from the internet, Windows adds the zone identifier or Mark of the Web as an NTFS stream to the file. So, when you run the file, Windows SmartScreen checks if there is a zone identifier Alternate Data Stream (ADS) attached to the file. If the ADS indicates ZoneId=3 which means that the file was downloaded from the internet, the SmartScreen does a reputation check. Exploiting this vulnerability, an attacker can craft a malicious file that would evade Mark of the Web (MOTW) defenses. The CVSS for this vulnerability is 5.4.

Amongst critical vulnerabilities, there is a Remote Code Execution (RCE) affecting the .Net Framework (CVE-2022-41089). The exploitability for this one is ‘less likely’ according to Microsoft. The CVSS is 8.8.

A second critical vulnerability is an RCE affecting Microsoft SharePoint Server (CVE-2022-44690). According to the advisory, in a network-based attack, an authenticated attacker with Manage List permissions could execute code remotely on the SharePoint Server. The CVSS for this vulnerability is 8.8.

Another critical vulnerability worth mentioning is an RCE in Powershell (CVE-2022-41076). The advisory says that the attack complexity is high as to exploit this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment. Additionally, it says that an authenticated attacker could escape the PowerShell Remoting Session Configuration and run unapproved commands on the target system. The CVSS for this vulnerability is 8.5.
