CVE-2025-24249

Comprehensive Technical Analysis of CVE-2025-24249

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-24249 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 significant impact on confidentiality, integrity, and availability. The permissions issue allows an application to check the existence of arbitrary paths on the file system, which can lead to information disclosure and potential escalation of privileges.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Information Disclosure: An attacker could exploit this vulnerability to determine the existence of sensitive files or directories, which could be used to plan further attacks.
• Privilege Escalation: By checking the existence of specific system files, an attacker might infer sensitive information that could aid in privilege escalation attempts.
• Data Exfiltration: Knowing the existence of certain files could help an attacker target specific data for exfiltration.

Exploitation Methods:

• Malicious Applications: An attacker could develop a malicious application that exploits this vulnerability to scan the file system for sensitive information.
• Phishing: Users could be tricked into installing malicious applications that exploit this vulnerability.
• Supply Chain Attacks: Compromising legitimate applications to include malicious code that exploits this vulnerability.

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:

• All applications running on the affected macOS versions that have the capability to interact with the file system.

4. Recommended Mitigation Strategies

Immediate Actions:

• Update Systems: Ensure that all affected macOS systems are updated to the latest versions (Ventura 13.7.5, Sequoia 15.4, Sonoma 14.7.5) where the vulnerability has been patched.
