• AV:N (Attack Vector: Network): The vulnerability can be exploited remotely over the network.
• AC:L (Attack Complexity: Low): The attack requires low complexity to exploit.
• PR:N (Privileges Required: None): No privileges are required to exploit the vulnerability.
• UI:N (User Interaction: None): No user interaction is required to exploit the vulnerability.
• S:U (Scope: Unchanged): The vulnerability does not change the security scope.
• C:H (Confidentiality: High): There is a high impact on confidentiality.
• I:H (Integrity: High): There is a high impact on integrity.
• A:H (Availability: High): There is a high impact on availability.

Given the high scores in confidentiality, integrity, and availability, this vulnerability poses a significant risk to affected systems.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is through malicious applications. An attacker could exploit this vulnerability by:

• Distributing Malicious Apps: Creating and distributing malicious applications that, when installed, can read or write to protected files.
• Phishing Campaigns: Using phishing techniques to trick users into downloading and installing malicious applications.
• Supply Chain Attacks: Compromising legitimate applications or their update mechanisms to deliver malicious payloads.

Exploitation methods could include:

• Data Exfiltration: Reading sensitive files and exfiltrating data to remote servers.
• Data Manipulation: Modifying protected files to disrupt system operations or inject malicious code.
• Persistent Access: Writing to protected files to establish persistent access or backdoors.

3. Affected Systems and Software Versions

The vulnerability affects the following versions of macOS:

• macOS Ventura versions prior to 13.7.5
• macOS Sequoia versions prior to 15.4
• macOS Sonoma versions prior to 14.7.5
