CVE ID: CVE-2025-24204 CVSS Score: 9.8

The CVSS score of 9.8 indicates that this vulnerability is critical. The high score is likely due to the potential for unauthorized access to protected user data, which can have severe implications for user privacy and security. The vulnerability has been addressed with improved checks in macOS Sequoia 15.4, suggesting that prior versions are susceptible to this issue.

2. Potential Attack Vectors and Exploitation Methods

Given the description, the vulnerability allows an app to access protected user data. Potential attack vectors include:

• Malicious Applications: An attacker could develop a malicious app that exploits this vulnerability to access sensitive user data.
• Compromised Legitimate Applications: An attacker could compromise a legitimate app to include malicious code that exploits this vulnerability.
• Phishing and Social Engineering: Attackers could use phishing techniques to trick users into installing malicious apps or updating legitimate apps with compromised versions.

Exploitation methods might involve:

• Bypassing Security Checks: The vulnerability suggests that there were insufficient checks in place, allowing unauthorized access to protected data.
• Privilege Escalation: Once an attacker gains initial access, they could escalate privileges to access more sensitive data.

3. Affected Systems and Software Versions

The vulnerability affects macOS versions prior to Sequoia 15.4. Users running older versions of macOS are at risk and should update to the latest version to mitigate this vulnerability.

4. Recommended Mitigation Strategies

• Update to the Latest Version: Users should update to macOS Sequoia 15.4 or later to benefit from the improved checks that address this vulnerability.
• Regular Patch Management: Implement a robust patch management program to ensure that all systems are updated promptly.
• Application Whitelisting: Use application whitelisting to prevent the execution of unauthorized or malicious applications.
• User Education: Educate users about the risks of installing apps from untrusted sources and the importance of keeping their systems updated.
• Monitoring and Detection: Implement monitoring and detection mechanisms to identify and respond to any suspicious activity that may indicate an exploitation attempt.

5. Impact on Cybersecurity Landscape
