CVE-2024-44190 is a path traversal vulnerability identified in Apple macOS that allows an application to read arbitrary files on the system. The root cause is insufficient validation of file path inputs, enabling an attacker-controlled app to bypass intended access controls and access files outside its permitted directories. This vulnerability is categorized under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). It affects multiple macOS versions prior to the patched releases: macOS Sequoia 15, Sonoma 14.7, and Ventura 13.7. The vulnerability requires the attacker to have local privileges (low-level privileges) but does not require user interaction, making it easier to exploit once local access is obtained. The CVSS v3.1 base score is 5.5, indicating medium severity, with the attack vector being local (AV:L), low complexity (AC:L), requiring privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high confidentiality impact (C:H) but no impact on integrity or availability. No known exploits have been reported in the wild yet. The issue was addressed by Apple through improved path validation to prevent unauthorized file reads. This vulnerability could be leveraged to access sensitive system or user files, potentially exposing confidential information to malicious local applications.

The primary impact of CVE-2024-44190 is unauthorized disclosure of sensitive information due to arbitrary file read capabilities by a local app. This can lead to leakage of confidential data such as credentials, personal information, or proprietary files stored on macOS devices. While it does not affect system integrity or availability, the confidentiality breach can have serious consequences for organizations handling sensitive or regulated data. Attackers with local access, including malicious insiders or compromised user accounts, could exploit this vulnerability to escalate information gathering and facilitate further attacks. The medium severity score reflects that exploitation requires local privileges, limiting remote attack scenarios but still posing a significant risk in environments with shared or multi-user systems. Organizations relying heavily on macOS for critical operations, especially those in regulated industries like finance, healthcare, and government, could face compliance and reputational risks if this vulnerability is exploited. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, emphasizing the need for timely patching.

To mitigate CVE-2024-44190, organizations should immediately deploy the security updates provided by Apple in macOS Sequoia 15, Sonoma 14.7, and Ventura 13.7 or later. Beyond patching, implement strict application whitelisting and sandboxing policies to limit the execution of untrusted or unnecessary applications that could exploit this vulnerability. Employ least privilege principles by restricting user and app permissions to the minimum necessary, reducing the risk of local privilege exploitation. Regularly audit file system permissions and monitor for unusual file access patterns that could indicate exploitation attempts. For environments with sensitive data, consider additional endpoint detection and response (EDR) solutions capable of detecting anomalous file access behaviors. Educate users about the risks of installing untrusted software and enforce strong local account security controls to prevent unauthorized local access. Finally, maintain up-to-date backups and incident response plans to quickly recover from any potential data breaches.
