CVE-2018-4468

Vulnerability

CVE-2018-4468 exists in macOS versions prior to the fixes. The issue occurs because certain entitlements were not properly removed, allowing a malicious application to bypass restrictions and access files that should be protected. Affected versions include macOS Sierra 10.12.6, macOS High Sierra 10.13.6, and earlier versions of macOS Mojave before 10.14.1. [1]

Exploitation

An attacker must have the ability to run a malicious application on the target system. No additional authentication or user interaction beyond launching the app is required. The application can then exploit the insufficient entitlement removal to access restricted files. [1]

Impact

Successful exploitation leads to unauthorized access to restricted files, resulting in information disclosure. The attacker gains access to files that are normally protected from applications, potentially exposing sensitive data. [1]

Mitigation

Apple addressed the issue in macOS Mojave 10.14.1, Security Update 2018-002 for High Sierra, and Security Update 2018-005 for Sierra. Users should update to these versions or later to mitigate the vulnerability. No workarounds are documented. [1]
