CVE-2025-24231

Vulnerability Allowing Modification of Protected File System on macOS

Published Mar 31, 2025 CVSS 3.1 · 9.8 Critical EPSS 1.1% KEV · Not listed

Description

The issue was addressed with improved checks. This issue is fixed in macOS Sequoia 15.4, macOS Sonoma 14.7.5, macOS Ventura 13.7.5. An app may be able to modify protected parts of the file system.

Analysis

Technical impact

The vulnerability could allow an application to modify protected parts of the file system. The description does not detail the exact exploitation mechanism, but the associated CWE‑787 suggests a buffer overflow or out‑of‑bounds write. This could compromise system integrity and confidentiality, and may enable privilege escalation if the flaw is triggered in a privileged context.

Affected Systems

Apple macOS is affected; the fix is delivered in macOS Sequoia 15.4, macOS Sonoma 14.7.5, and macOS Ventura 13.7.5. No other versions are confirmed to be vulnerable, but any macOS system not updated to at least one of these releases may still be at risk.

Risk and Exploitability

The CVSS score of 9.8 indicates critical severity. EPSS indicates a very low probability of exploitation, and the vulnerability is not listed in CISA’s KEV catalog. The likely attack vector is local: an attacker able to run a malicious or compromised application could potentially trigger the flaw and modify protected filesystem components. If a user runs such software, the exploit could result in system compromise.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

Apply the macOS update to at least Sequoia 15.4, Sonoma 14.7.5, or Ventura 13.7.5 on every affected machine.
If immediate update is not possible, restrict the application using Gatekeeper and the system’s sandbox features to limit its ability to touch protected directories, and consider disabling any unnecessary privileged services via System Preferences > Security & Privacy.
Monitor system logs for unauthorized file modifications and configure alerts for changes to critical system directories.
