CVE-2022-42847 is a high-severity vulnerability affecting Apple macOS. Specifically, it is an out-of-bounds write issue that has been addressed through enhanced input validation. The vulnerability can allow an application to execute arbitrary code with kernel privileges, posing significant risk to users and systems.
With a CVSS score of 7.8, this vulnerability is classified as high severity. The impact of this vulnerability is particularly concerning, as it can compromise confidentiality, integrity, and availability of the system. Organizations running vulnerable versions of macOS should consider the urgency of remediation.
The issue was published on December 15, 2022, and Apple has released a fix in macOS Ventura 13.1. It is critical that organizations prioritize patching to address this vulnerability, as failure to do so could lead to exploitation.
Given the high potential for exploitation, organizations should take immediate action to ensure their systems are updated. Current information suggests that there are no known exploits in the wild, but the nature of the vulnerability means that attackers may seek to leverage it.
Vulnerability Details
The official description of CVE-2022-42847 indicates that this vulnerability allows an out-of-bounds write due to inadequate input validation. The CVSS score of 7.8 indicates a high severity level, with significant potential impacts on confidentiality, integrity, and availability.
The affected product is macOS, specifically all versions prior to macOS Ventura 13.1. This vulnerability falls under the CWE-787 classification, which pertains to out-of-bounds writes.
Technical Analysis
The root cause of CVE-2022-42847 stems from insufficient input validation, which allows for an out-of-bounds write. The attack vector is local, meaning that an attacker must have access to the local system, typically requiring user interaction to exploit the vulnerability.
The attack complexity is low, and no privileges are required to exploit the vulnerability. However, user interaction is necessary, as the attacker likely needs to convince the user to execute a malicious application.
Given the potential for high impact on confidentiality, integrity, and availability, the vulnerability poses a significant risk to organizations utilizing affected versions of macOS.
Risk & Impact Analysis
The real-world risk of exploiting CVE-2022-42847 is substantial. Attackers may leverage this vulnerability to execute arbitrary code at a high privilege level, which could lead to unauthorized access to sensitive data or complete system compromise.
Organizations should assess the potential blast radius of this vulnerability, particularly in environments where macOS systems are deployed. The urgency for remediation is high, as the vulnerability could be exploited by malicious actors.
