1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-24207 CVSS Score: 9.8

The CVSS score of 9.8 indicates a critical vulnerability. This high score is likely due to the potential for unauthorized access to sensitive data and the ability to bypass user consent mechanisms, which are fundamental to data privacy and security.

Severity Evaluation:

• Confidentiality Impact: High
• Integrity Impact: High
• Availability Impact: Medium

The vulnerability allows an application to enable iCloud storage features without user consent, potentially leading to unauthorized access to user data stored in iCloud. This can result in significant confidentiality and integrity impacts, as well as potential availability issues if the data is manipulated or deleted.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Malicious Applications: An attacker could develop a malicious app that exploits this vulnerability to enable iCloud storage features without the user's knowledge or consent.
• Compromised Legitimate Applications: An attacker could compromise a legitimate application to include malicious code that exploits this vulnerability.

Exploitation Methods:

• Social Engineering: Attackers could use social engineering techniques to trick users into installing malicious apps.
• Supply Chain Attacks: Attackers could compromise the software supply chain to inject malicious code into legitimate applications.

3. Affected Systems and Software Versions

Affected Systems:

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

Software Versions:
