CVE-2023-40412 is a high-severity vulnerability that impacts several Apple products, including macOS Ventura, iOS, iPadOS, tvOS, and watchOS. This vulnerability allows an application to execute arbitrary code with kernel privileges due to inadequate memory handling. The vulnerability has a CVSS score of 7.8, indicating its potential for significant impact.
The risk to organizations includes unauthorized access and control over affected devices, potentially leading to data breaches or further exploitation of the system. Given the severity of this vulnerability, it is critical for organizations to address it promptly.
As of now, there are no public exploits or proof of concept available for this vulnerability. However, given its nature and the fact that it can be exploited locally with user interaction, organizations should be vigilant.
Organizations should prioritize patching immediately. Fixes for this vulnerability are available in macOS Ventura 13.6, tvOS 17, macOS Monterey 12.7, watchOS 10, iOS 17, and iPadOS 17.
Vulnerability Details
The issue was addressed with improved memory handling. This issue is fixed in macOS Ventura 13.6, tvOS 17, macOS Monterey 12.7, watchOS 10, iOS 17 and iPadOS 17. An app may be able to execute arbitrary code with kernel privileges.
The vulnerability has a CVSS score of 7.8, classified as high severity due to its potential impact on confidentiality, integrity, and availability. It has been assigned a local attack vector with low complexity, requiring no privileges, but necessitating user interaction.
Technical Analysis
The root cause of this vulnerability stems from improper memory handling within the affected Apple products. Attackers may leverage this weakness to execute arbitrary code with kernel privileges. The attack vector is local, meaning the attacker must have physical access to the device. The attack complexity is classified as low, and no privileges are required, but user interaction is necessary.
The confidentiality, integrity, and availability impacts are all rated as high, indicating that successful exploitation could lead to significant breaches of sensitive data and system controls.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to sensitive data and the ability to manipulate system functionality. Given the widespread use of Apple products in various sectors, the potential blast radius is significant. This vulnerability's high CVSS score indicates that it should be addressed immediately in the patching cycle.
