CVE-2023-32364 is a high-severity vulnerability affecting Apple macOS. This vulnerability allows a logic issue that could be exploited by a sandboxed process to circumvent sandbox restrictions. The CVSS score for this vulnerability is 8.6, indicating a high level of risk due to its potential impact on confidentiality, integrity, and availability.
The nature of this vulnerability means that it poses a significant risk to organizations using affected versions of macOS. Attackers may leverage this weakness to gain unauthorized access to sensitive data or perform actions outside the intended constraints of the operating system. Organizations should prioritize patching immediately.
The vulnerability was published on July 27, 2023, and Apple has released fixes in macOS Ventura 13.5. It is crucial for users to update their systems to mitigate the potential risks associated with this vulnerability.
As of this writing, there is no confirmed public exploit, but the existence of a proof-of-concept on GitHub indicates that the vulnerability is being actively researched. Organizations should remain vigilant and monitor for any potential exploitation attempts.
Vulnerability Details
The vulnerability is characterized as a logic issue that was addressed with improved restrictions. This issue is fixed in macOS Ventura 13.5. The attack vector is local, and it requires user interaction to exploit, making it a serious concern for users who may inadvertently trigger the exploit.
The CVSS score of 8.6 indicates high severity due to its potential to impact confidentiality, integrity, and availability significantly. The affected versions include all macOS versions prior to 13.5, specifically versions 11.0 to 11.7.8, 12.0.0 to 12.6.7, and 13.0 to 13.4.
Technical Analysis
The root cause of this vulnerability lies in the logic used to enforce sandbox restrictions within macOS. The attack vector is local, meaning that the attacker must have access to the target device. The attack complexity is low, and no privileges are required, although user interaction is necessary to exploit the vulnerability.
This vulnerability presents a high risk to confidentiality, integrity, and availability, as it allows unauthorized access to sensitive data and system functionalities that should be restricted by the sandboxing mechanism.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data and potential system compromise. The blast radius of this vulnerability could be extensive, especially in environments where multiple applications rely on the macOS sandboxing features.
Given the high CVSS score and the nature of the vulnerability, organizations should address this issue in their priority patch cycle. Failure to patch could lead to significant security incidents, particularly if attackers leverage this vulnerability in targeted attacks.
