CVE-2024-44295 is a vulnerability identified in Apple macOS that permits an application to modify protected parts of the file system due to inadequate entitlement checks. Entitlements in macOS are security mechanisms that define what resources and capabilities an app can access. This vulnerability allows an app, without requiring any privileges or user interaction, to bypass these entitlement restrictions and alter critical system files or directories that are normally protected to maintain system integrity and security. The flaw was addressed by Apple through enhanced entitlement verification in macOS Sequoia 15.1, Sonoma 14.7.1, and Ventura 13.7.1. The CVSS 3.1 base score is 7.7, reflecting high severity, with an attack vector classified as local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality and integrity (C:H/I:H), but no impact on availability (A:N). This means an attacker with local access can exploit this vulnerability to gain unauthorized write access to protected system areas, potentially leading to privilege escalation, persistence, or system compromise. No public exploits have been reported yet, but the vulnerability poses a significant risk if leveraged by malicious actors. The vulnerability affects all macOS versions prior to the patched releases, and the issue was reserved in August 2024 and published in October 2024.

The primary impact of CVE-2024-44295 is the unauthorized modification of protected system files and directories, which can severely compromise system integrity and confidentiality. Attackers exploiting this vulnerability could alter system binaries, configuration files, or security settings, enabling privilege escalation, persistence mechanisms, or disabling security controls. This can lead to unauthorized access to sensitive data, installation of persistent malware, or disruption of system security policies. Since no user interaction or privileges are required, the attack surface is broad for any local user or malicious app. Organizations relying on macOS for critical operations, especially in sectors like government, finance, healthcare, and technology, face risks of data breaches, operational disruption, and loss of trust. The absence of known exploits in the wild currently limits immediate widespread impact, but the vulnerability's nature makes it a prime target for attackers once exploit code becomes available.

To mitigate CVE-2024-44295, organizations and users should promptly apply the security updates released by Apple in macOS Sequoia 15.1, Sonoma 14.7.1, and Ventura 13.7.1. Beyond patching, administrators should audit installed applications for unusual entitlement requests or behaviors that could indicate attempts to exploit entitlement weaknesses. Restricting app installation to trusted sources such as the Apple App Store or enterprise-signed applications reduces risk. Employing endpoint detection and response (EDR) solutions to monitor file system changes in protected directories can help detect exploitation attempts. Implementing strict access controls and least privilege principles for local users further limits the potential for exploitation. Regularly reviewing system logs and employing integrity monitoring tools can provide early warning of unauthorized modifications. Finally, educating users about the risks of installing untrusted software and maintaining robust backup strategies ensures resilience against potential compromise.
