CVE-2024-44301 is a vulnerability in Apple macOS identified as CWE-863 (Incorrect Authorization). It allows a malicious application to bypass security checks and modify protected parts of the file system that are normally restricted to system processes or privileged users. The vulnerability stems from insufficient enforcement of authorization policies, permitting unauthorized integrity modifications. The CVSS 3.1 base score is 5.5 (medium), with an attack vector of local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), no confidentiality impact (C:N), high integrity impact (I:H), and no availability impact (A:N). This means an attacker must have local access and trick a user into running a malicious app to exploit the flaw. Successful exploitation could allow the attacker to alter critical system files or configurations, potentially enabling persistence, privilege escalation, or disabling security controls. The vulnerability affects macOS versions prior to Sequoia 15.1, Sonoma 14.7.1, and Ventura 13.7.1, where Apple has implemented improved authorization checks to mitigate the issue. No public exploits or active exploitation have been reported yet, but the potential for misuse exists given the integrity impact. This vulnerability highlights the importance of strict authorization enforcement in protecting system integrity on macOS platforms.

The primary impact of CVE-2024-44301 is on system integrity, as it allows unauthorized modification of protected file system areas. This can lead to attackers implanting persistent malware, altering system configurations, or disabling security mechanisms, which can facilitate further attacks such as privilege escalation or data manipulation. Although confidentiality and availability are not directly affected, the integrity compromise can indirectly lead to broader security breaches. Organizations relying on macOS for critical operations, especially those with sensitive or regulated data, face increased risk of targeted attacks leveraging this vulnerability. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk, especially in environments with lax endpoint controls or where users may be socially engineered. The absence of known exploits in the wild reduces immediate threat but does not preclude future exploitation. Overall, the vulnerability could undermine trust in affected systems and increase incident response costs if exploited.

1. Apply the latest macOS updates immediately, specifically macOS Sequoia 15.1, Sonoma 14.7.1, or Ventura 13.7.1 or later, which contain the fix for this vulnerability. 2. Restrict installation of applications to trusted sources such as the Apple App Store and verified developers to reduce the risk of malicious app execution. 3. Employ endpoint protection solutions capable of monitoring and alerting on unauthorized modifications to protected file system areas. 4. Educate users on the risks of running untrusted applications and the importance of avoiding suspicious prompts requiring interaction. 5. Implement strict user privilege management to minimize the number of users with local access rights that could be exploited. 6. Use system integrity protection (SIP) and other macOS security features to limit the ability of applications to modify critical system files. 7. Regularly audit system logs and file integrity to detect anomalous changes indicative of exploitation attempts. 8. Consider application whitelisting and sandboxing to further constrain application behavior and reduce attack surface.
