CVE-2025-24136 is a medium-severity vulnerability affecting Apple macOS. This vulnerability allows a malicious application to create symbolic links to protected regions of the disk, potentially leading to unauthorized access to sensitive information. The CVSS score for this vulnerability is 4.4, indicating a moderate level of risk. Organizations using affected versions of macOS should prioritize remediation efforts to mitigate this risk.
The urgency for organizations is high; they should prioritize patching immediately. This vulnerability poses a real-world risk as attackers may leverage it to gain unauthorized access to critical system areas.
The vulnerability was published on January 27, 2025, and affects multiple versions of macOS: Sequoia 15.3, Sonoma 14.7.3, and Ventura 13.7.3. Users are encouraged to update their systems to ensure protection against potential exploitation.
Risk to organizations includes the potential for unauthorized access and manipulation of sensitive data. It is crucial for security teams to assess their systems for this vulnerability and implement the necessary patches.
No public exploit has been confirmed, and the vulnerability is not currently listed in the Known Exploited Vulnerabilities (KEV) database, indicating a lower likelihood of immediate exploitation in the wild. However, organizations should remain vigilant and proactive in addressing this risk.
Vulnerability Details
This issue was addressed with improved validation of symlinks. A malicious app may be able to create symlinks to protected regions of the disk, which could allow unauthorized operations on sensitive data. The CVSS score of 4.4 reflects the medium severity, with an attack vector classified as local, and a low complexity requirement.
The vulnerability is associated with CWE-59, which concerns symbolic link following vulnerabilities. This classification highlights the potential risks inherent in improper validation of symlinks.
Technical Analysis
The root cause of this vulnerability lies in the failure to properly validate symbolic links, which allows malicious applications to manipulate system paths. The attack vector is local, meaning that an attacker would need to have access to the system to exploit this vulnerability.
The attack complexity is low, as it does not require elevated privileges or significant user interaction; however, user interaction is still required to initiate the malicious application. The potential impacts on confidentiality and integrity are low, while there is no impact on availability.
Risk & Impact Analysis
Organizations should consider the deployment risk associated with this vulnerability. The potential for unauthorized access to protected regions of the disk could lead to significant data breaches or manipulation of critical system areas. The blast radius could be extensive if exploited, particularly if the malicious application is executed in a privileged context.
Given the CVSS score of 4.4, the urgency for organizations to address this vulnerability should be classified as medium. Organizations should schedule remediation as part of their standard patch management processes.
