Patch Tuesday is once again upon us. The October 2022 edition of Patch Tuesday brings us 89 fixes, with 13 rated as critical. We’ve listed the most important changes below.
⚡ TL;DR | Go Straight to the October 2022 Patch Tuesday Audit Report
Microsoft SharePoint Server RCE Vulnerability
One of the most critical vulnerabilities is in Sharepoint. CVE-2022-41038 received a CVSS base score of 8.8. Luckily, an attacker must both be authenticated to the target site and also have permission to access and use the Manage List within Sharepoint. The exploitation of this vulnerability could allow attackers to execute code remotely on your SharePoint servers.
Microsoft lists that luckily the vulnerability is not being actively exploited yet, but stresses that exploitation is likely, so best to update your SharePoint servers as soon as possible.
Additionally, three less severe vulnerabilities were also fixed for SharePoint. CVE-2022-41037, CVE-2022-41036, and CVE-2022-38053 are all three RCE vulnerabilities with a CVSS score of 8.8. However, Microsoft doesn’t rate them as critical.
Windows Point-to-Point Tunneling Protocol RCE
A staggering 7 of the critical vulnerabilities are in the Windows point-to-point tunneling protocol. All received a CVSS base score of 8.1.
Microsofts comments that for an attacker to exploit the vulnerability, they would need to send a specially crafted malicious PPTP packet to a PPTP server. If successful attackers are able to remotely execute code on the target machine.
Azure Arc-enabled Kubernetes cluster Connect Elevation of Privilege Vulnerability
The last major vulnerability is in the cluster connect feature of Azure Arc-enabled Kubernetes clusters. Because the Azure Stack Edge allows users to deploy Kubernetes workloads on devices via Azure Arc, Azure Stack Edge devices are also deemed as vulnerable.
CVE-2022-37968 received a max CVSS base score of 10, and while Microsoft doesn’t list exploitability as likely, the ease of exploitation does make it a high priority if you’re using the cluster connect feature. Microsoft added additional guidance in their security center.
„An attacker who knows the randomly generated external DNS endpoint for an Azure Arc-enabled Kubernetes cluster can exploit this vulnerability from the internet. Successful exploitation of this vulnerability, which affects the cluster connect feature of Azure Arc-enabled Kubernetes clusters, allows an unauthenticated user to elevate their privileges as cluster admins and potentially gain control over the Kubernetes cluster.“
