CVE-2024-54471 is a vulnerability identified in Apple macOS that allows a malicious application to leak user credentials due to insufficient entitlement checks. Entitlements in macOS are security mechanisms that restrict application capabilities; failure to enforce these properly can allow unauthorized access to sensitive information. This vulnerability requires the attacker to have local access (AV:L - Attack Vector: Local) and user interaction (UI:R - User Interaction: Required), but does not require privileges (PR:N - Privileges Required: None). The vulnerability impacts confidentiality (C:H - High) but does not affect integrity or availability. The issue was addressed by Apple through additional entitlement checks in macOS Sequoia 15.1, Sonoma 14.7.1, and Ventura 13.7.1. The vulnerability is categorized under CWE-522, which relates to insufficiently protected credentials. Although no exploits are currently known in the wild, the potential for credential leakage poses a significant risk, especially in environments where sensitive user credentials are stored or used. The CVSS score of 5.5 reflects a medium severity, balancing the local attack vector and user interaction requirement against the high confidentiality impact. This vulnerability highlights the importance of strict entitlement enforcement and application sandboxing in macOS to prevent unauthorized access to user credentials.

The primary impact of CVE-2024-54471 is the potential leakage of user credentials, which can lead to unauthorized access to user accounts and sensitive data. Credential leakage can facilitate further attacks such as privilege escalation, lateral movement within networks, and data exfiltration. Although the vulnerability does not affect system integrity or availability directly, the compromise of credentials undermines overall system security and trust. Organizations relying on macOS devices for sensitive operations, including enterprises, government agencies, and technology firms, face increased risk of data breaches and insider threats if this vulnerability is exploited. The requirement for local access and user interaction limits remote exploitation but does not eliminate risk, especially in environments where users may be tricked into executing malicious applications. The absence of known exploits in the wild suggests limited current threat activity, but the vulnerability should be treated proactively to prevent future exploitation. Failure to address this vulnerability could result in significant confidentiality breaches and associated regulatory or reputational damage.

1. Apply the official Apple patches by upgrading to macOS Sequoia 15.1, Sonoma 14.7.1, or Ventura 13.7.1 or later versions where the vulnerability is fixed. 2. Implement strict application whitelisting and control to prevent installation or execution of untrusted or malicious applications. 3. Educate users about the risks of running unknown applications and the importance of verifying software sources to reduce the likelihood of user interaction exploitation. 4. Utilize endpoint detection and response (EDR) solutions to monitor for suspicious behavior indicative of credential access or leakage attempts. 5. Enforce least privilege principles and limit local user permissions to reduce the attack surface. 6. Regularly audit entitlement configurations and application permissions to ensure no excessive privileges are granted. 7. Employ multi-factor authentication (MFA) to mitigate the impact of leaked credentials by requiring additional verification factors. 8. Monitor system logs and credential access patterns for anomalies that could indicate exploitation attempts. These measures collectively reduce the risk of exploitation and limit potential damage from credential leakage.
