Vulnerability Details
This vulnerability allows an application to potentially access sensitive user data due to a downgrade issue, which has now been addressed with additional code-signing restrictions. The vulnerability is fixed in macOS Sequoia 15.3, macOS Sonoma 14.7.3, and macOS Ventura 13.7.3.
The CVSS score of 5.5 (medium severity) indicates a local attack vector with low attack complexity, requiring no privileges and user interaction. The confidentiality impact is rated high, while integrity and availability impacts are none.
The vulnerability was published on January 27, 2025, and is classified under CWE-200, which refers to exposure of sensitive information to an unauthorized actor.
Technical Analysis
The root cause of CVE-2025-24109 is the inadequate implementation of code-signing restrictions that previously allowed for the possibility of a downgrade attack. Attackers may leverage this vulnerability by tricking the system into accepting an insecure version of an application, potentially leading to unauthorized access to sensitive user data.
The attack vector is local, meaning that an attacker must have physical access to the affected system. The attack complexity is low, implying that the exploitation of this vulnerability does not require advanced skills or knowledge. No privileges are required to execute this attack, and user interaction is necessary to trigger the vulnerability.
This vulnerability has a high confidentiality impact because it could allow unauthorized access to sensitive information. However, it has no integrity or availability impact, meaning that the system's performance and data integrity remain intact.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-24109 is significant due to the potential for unauthorized access to sensitive user data. Organizations using affected versions of macOS should recognize that the risk includes exposure of confidential information, which could have severe implications for user privacy and data protection regulations.
The urgency for organizations to address this vulnerability is underscored by its medium CVSS score of 5.5. This level of severity indicates that it should be addressed in the priority patch cycle. Organizations should be aware that maintaining up-to-date systems is critical in minimizing the attack surface and mitigating risks.
The potential blast radius of this vulnerability could extend to any applications running on the affected versions of macOS, making it crucial for organizations to implement timely updates.
