CVE-2024-44156 is a vulnerability identified in Apple macOS that allows an application to bypass the system's Privacy preferences, potentially granting unauthorized access to protected resources or data. The root cause is a path deletion vulnerability that previously allowed certain code paths to execute with elevated privileges improperly. This flaw is categorized under CWE-862 (Missing Authorization), indicating that the system failed to enforce proper authorization checks before allowing access to sensitive operations. The vulnerability affects multiple macOS versions prior to the patched releases: macOS Sequoia 15.1, macOS Sonoma 14.7.1, and macOS Ventura 13.7.1. The CVSS v3.1 base score is 7.1, reflecting a high severity level, with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), and high confidentiality and integrity impacts (C:H/I:H), but no impact on availability (A:N). The fix implemented by Apple involves preventing the vulnerable code from running with elevated privileges, thereby closing the authorization bypass. While no active exploitation has been reported, the vulnerability could be leveraged by malicious local applications or attackers with limited access to escalate privileges or access sensitive user data protected by macOS Privacy preferences. This vulnerability underscores the importance of strict authorization enforcement in operating system security controls.

The potential impact of CVE-2024-44156 is significant for organizations and individual users relying on macOS systems. By bypassing Privacy preferences, malicious applications or attackers with local access can gain unauthorized access to sensitive user data, such as contacts, calendars, location data, or other protected resources. This breach of confidentiality can lead to data leakage, privacy violations, and potential exposure of personally identifiable information (PII). The integrity of user data and system configurations may also be compromised if unauthorized modifications are made. Although availability is not impacted, the loss of confidentiality and integrity can undermine trust in macOS security and lead to compliance issues, especially for organizations subject to data protection regulations. The requirement for local access and low privileges means that attackers must already have some foothold on the system, but the lack of user interaction needed makes exploitation more feasible in automated or stealthy attack scenarios. Enterprises with macOS endpoints, especially in sectors like finance, healthcare, and government, face increased risk if systems remain unpatched. Additionally, the vulnerability could be leveraged as part of a multi-stage attack chain to escalate privileges or move laterally within a network.

To mitigate CVE-2024-44156, organizations and users should immediately apply the security updates provided by Apple in macOS Sequoia 15.1, Sonoma 14.7.1, and Ventura 13.7.1 or later. Beyond patching, organizations should implement strict application control policies to limit the execution of untrusted or unsigned applications, reducing the risk of local malicious code execution. Employ endpoint detection and response (EDR) solutions capable of monitoring for suspicious local privilege escalation attempts or unauthorized access to privacy-protected resources. Regularly audit and restrict user privileges to the minimum necessary, preventing attackers from easily gaining the low privileges required for exploitation. Enable macOS built-in security features such as System Integrity Protection (SIP) and Transparency, Consent, and Control (TCC) to enforce privacy protections robustly. Conduct user awareness training to recognize and avoid installing potentially malicious software. For high-security environments, consider network segmentation and monitoring to detect lateral movement attempts that might follow exploitation. Finally, maintain an up-to-date inventory of macOS devices and ensure timely patch management processes are in place to rapidly address vulnerabilities.
