CVE-2024-40792 is a permissions-related vulnerability in Apple macOS identified as CWE-276 (Incorrect Default Permissions). The issue stems from insufficient restrictions on the ability of applications to modify network settings. A malicious application with limited privileges (PR:L) but no user interaction (UI:N) can exploit this flaw to alter network configurations, potentially redirecting traffic or disrupting network connectivity. The vulnerability affects macOS versions prior to the release of macOS Sequoia 15, where Apple implemented additional permission restrictions to mitigate this risk. The CVSS v3.1 base score is 3.3, reflecting a low severity primarily due to the requirement for local access and limited impact on confidentiality and availability. The integrity of network settings is the main concern, as unauthorized changes could facilitate man-in-the-middle attacks or network disruptions. No public exploits or active exploitation have been reported. This vulnerability highlights the importance of strict permission controls for system configuration changes on macOS platforms.

The primary impact of CVE-2024-40792 is on the integrity of network settings within affected macOS systems. A malicious app exploiting this vulnerability could alter network configurations, such as DNS settings, proxy configurations, or routing tables, potentially redirecting or intercepting network traffic. While confidentiality and availability are not directly compromised, these changes could enable further attacks like data interception, phishing, or denial of service through network misconfiguration. Organizations relying on macOS devices, especially in sensitive or high-security environments, may face increased risk of targeted attacks or operational disruptions. However, the requirement for local privileges and the absence of user interaction reduce the likelihood of widespread exploitation. The lack of known exploits in the wild further limits immediate risk but does not eliminate the need for remediation.

To mitigate CVE-2024-40792, organizations should prioritize updating all macOS devices to macOS Sequoia 15 or later, where the vulnerability is fixed with enhanced permission restrictions. Implement strict application control policies to limit the installation and execution of untrusted or unsigned applications that could exploit this flaw. Employ endpoint security solutions capable of monitoring and alerting on unauthorized changes to network settings. Regularly audit network configuration changes and maintain logs to detect suspicious activity. For environments with sensitive data or critical operations, consider restricting local user privileges to the minimum necessary and enforce the principle of least privilege. Additionally, educate users about the risks of installing unverified software and maintain up-to-date backups to recover from potential misconfigurations.
