CVE-2024-44293 is a privacy vulnerability identified in Apple macOS, specifically addressed in macOS Sequoia 15.1. The flaw arises from insufficient redaction of sensitive user information in system log entries, which could allow a user with limited privileges (local access with low privileges) to view sensitive data that should otherwise be protected. The vulnerability does not require user interaction and does not impact system integrity or availability, focusing solely on confidentiality breaches. The CVSS v3.1 score is 5.5 (medium severity), reflecting the local attack vector (AV:L), low attack complexity (AC:L), and low privileges required (PR:L), with no user interaction (UI:N). The scope remains unchanged (S:U), and the impact is high on confidentiality (C:H), none on integrity (I:N) and availability (A:N). The root cause relates to improper handling and redaction of private data in logs, which can expose sensitive information to unauthorized users. Apple resolved this issue by enhancing private data redaction mechanisms in log entries in the macOS Sequoia 15.1 update. There are no known exploits in the wild, but the vulnerability represents a privacy risk for users and organizations relying on macOS systems. The CWE associated is CWE-352, indicating a potential cross-site request forgery or related weakness in data handling.

The primary impact of CVE-2024-44293 is the unauthorized disclosure of sensitive user information through system logs, which compromises confidentiality. This can lead to privacy violations, potential exposure of personally identifiable information (PII), credentials, or other sensitive data that could be leveraged for further attacks such as social engineering or privilege escalation. Since exploitation requires local access with low privileges, attackers who have gained limited access to a macOS system could escalate their knowledge of the environment and users. Although the vulnerability does not affect system integrity or availability, the breach of confidentiality can have serious repercussions for organizations handling sensitive data, including regulatory compliance issues (e.g., GDPR, HIPAA). The lack of known exploits reduces immediate risk, but the presence of this vulnerability in widely used macOS systems means that organizations globally could be targeted if attackers develop exploit techniques. The impact is particularly significant for environments with multiple users or shared systems, where one user could access sensitive information about others.

To mitigate CVE-2024-44293, organizations and users should promptly update all macOS systems to version Sequoia 15.1 or later, where the issue is fixed. Beyond patching, administrators should audit and restrict local user privileges to minimize the number of users with access to sensitive logs. Implement strict access controls and monitoring on log files to detect unauthorized access attempts. Consider encrypting sensitive logs or using centralized logging with controlled access to reduce exposure on local machines. Regularly review and sanitize logs to ensure no sensitive information is unnecessarily recorded. Employ endpoint detection and response (EDR) solutions to monitor for suspicious local activity that could indicate attempts to exploit such vulnerabilities. Educate users about the risks of local privilege misuse and enforce strong physical and logical security controls to prevent unauthorized local access. Finally, maintain an up-to-date inventory of macOS devices and ensure timely application of security updates.
