CVE-2023-42929 is a medium-severity vulnerability in Apple macOS, specifically affecting versions prior to macOS Sonoma 14. This vulnerability allows unauthorized applications to access protected user data, raising significant confidentiality concerns. The issue stems from inadequate checks within the operating system, which have since been addressed in the latest security update.
With a CVSS score of 5.5, this vulnerability represents a moderate risk level for organizations running affected versions of macOS. Given the nature of the vulnerability, an attacker may exploit it to gain access to sensitive user information, potentially leading to data breaches or further exploitation.
Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability. The urgency is highlighted by the fact that user interaction is required for an application to exploit this issue, meaning that end-user behavior could influence the likelihood of a successful attack.
As of now, no public exploits are confirmed for CVE-2023-42929, and it has not been included in the Known Exploited Vulnerabilities (KEV) database. However, organizations should remain vigilant and take proactive measures to secure their systems.
Vulnerability Details
The issue was addressed with improved checks in macOS Sonoma 14. The vulnerability is classified as having a confidentiality impact of high, while integrity and availability impacts are marked as none. The vulnerability affects all versions of macOS prior to 14.0.
Technical Analysis
The root cause of CVE-2023-42929 lies in the insufficient checks implemented within the macOS environment, allowing unauthorized applications to access protected user data. The attack vector is local, requiring physical access or an already compromised application to exploit the vulnerability. The complexity of the attack is low, and no privileges are required to execute the exploit, although user interaction is necessary.
In terms of impacts, the vulnerability primarily affects confidentiality, as attackers could potentially access sensitive user information. The integrity and availability of the system remain unaffected, which marginally reduces the overall risk profile associated with this vulnerability.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive user data, which could lead to data breaches and compromise user trust. As this vulnerability affects all versions prior to macOS Sonoma 14, organizations utilizing outdated systems are particularly at risk. The potential blast radius could be significant, especially in environments where sensitive data is routinely accessed.
Given the CVSS score of 5.5 and the absence of known exploits, the urgency for patching is marked as medium. However, organizations should remain proactive in their security practices and consider the implications of this vulnerability on their overall security posture.
