Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-24093 is a permissions vulnerability classified under CWE-276 (Incorrect Default Permissions) affecting Apple's macOS operating system. The issue allows an app to access removable volumes, such as USB drives, without user consent due to insufficient restrictions on permissions. It impacts macOS Sequoia versions prior to 15.4, macOS Sonoma prior to 14.7.3, and macOS Ventura prior to 13.7.3. The vulnerability received a CVSS v3.1 base score of 9.8 (Critical), reflecting network accessibility (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H).
Any remote attacker can exploit this vulnerability by delivering a malicious app to a target system, enabling the app to read from or write to removable volumes without prompting the user. No special privileges or local access are needed, and exploitation requires only low complexity over the network. Successful exploitation grants the attacker unauthorized access to sensitive data on attached removable media, potentially allowing theft, modification, or deletion of files.
Apple's security advisories detail the fix through additional permissions restrictions in the specified macOS updates: Sequoia 15.4, Sonoma 14.7.3, and Ventura 13.7.3. Security practitioners should prioritize patching affected systems, as outlined in the referenced support pages (e.g., https://support.apple.com/en-us/122069), and monitor for full disclosure discussions on platforms like seclists.org.

Mitigating Controls (NIST 800-53 r5) AI
Enforces approved authorizations on files and resources so overly permissive defaults cannot be exploited.
Requires least-privilege defaults so that installed files are not world-writable by default.
Requires documented, restrictive configuration settings that cover file and directory permissions.
Enforces access restrictions on changes, including permission settings applied during installation or configuration.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Hardened baselines and configuration management explicitly require correct default file permissions.
Defining and enforcing least-privilege access permissions directly prevents overly permissive defaults at install time.
Lifecycle management can encompass permission settings, yet the control is too broad to specifically mitigate incorrect defaults.
Secure SDLC practices include establishing secure defaults, but address only the development-phase portion of the weakness.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Standard templates that restrict access to utility programs and host parameter settings prevent the assignment of overly permissive default permissions on critical resources.
