CVE-2018-4414

Vulnerability

A memory corruption issue existed in the CFNetwork component of multiple Apple operating systems. This vulnerability, tracked as CVE-2018-4414, was disclosed in security advisories for iOS 12, macOS Mojave 10.14, tvOS 12, watchOS 5, iTunes 12.9 for Windows, and iCloud for Windows 7.7. The official Apple description states that the issue was addressed with improved input validation [1][4].

Exploitation

An attacker would need to have the ability to run a malicious application on an affected device. No additional privileges or user interaction are required beyond launching the application. The application can trigger the memory corruption by sending crafted input to the CFNetwork component [4].

Impact

Successful exploitation allows a malicious application to execute arbitrary code with system privileges, potentially giving the attacker complete control over the affected device. This represents a full compromise of the system's security [4].

Mitigation

Apple released security updates for iOS 12, macOS Mojave 10.14, tvOS 12, watchOS 5, iTunes 12.9 for Windows, and iCloud for Windows 7.7 on September 17-24, 2018 [1][2][3][4]. Users should update their devices to the latest available versions. There are no known workarounds.
