Apple Products Could Allow for Arbitrary Code Execution

by | Apr 27, 2021 | Advisories

Multiple vulnerabilities have been discovered in Apple Products, the most severe of which could allow for arbitrary code execution.

  • iCloud for Windows is a cloud storage and cloud computing service.
  • Xcode is an integrated development environment (IDE) for macOS.
  • Safari is a graphical web browser developed by Apple, based on the WebKit engine.
  • macOS Big Sur is the 17th and current major release of macOS.
  • macOS Catalina is the 16th major release of macOS.
  • macOS Mojave is the 15th major release of macOS.
  • iOS is a mobile operating system for mobile devices, including the iPhone, iPad, and iPod touch.
  • iPadOS is the successor to iOS 12 and is a mobile operating system for iPads.
  • watchOS is the mobile operating system for the Apple Watch and is based on the iOS operating system.
  • tvOS is an operating system for the fourth-generation Apple TV digital media player.
  • iTunes for Windows is a media player, media library, Internet radio broadcaster, mobile device management utility, and the client app for the iTunes Store.
  • GarageBand is a line of digital audio workstations for macOS, iPadOS, and iOS devices that allows users to create music or podcasts.

Successful exploitation of the most severe of these vulnerabilities could result in arbitrary code execution within the context of the application, an attacker gaining the same privileges as the logged-on user, or the bypassing of security restrictions. Depending on the permission associated with the application running the exploit, an attacker could then install programs; view, change, or delete data.

Successful exploitation of the most severe of these vulnerabilities could result in arbitrary code execution within the context of the application, an attacker gaining the same privileges as the logged-on user, or the bypassing of security restrictions. Depending on the permission associated with the application running the exploit, an attacker could then install programs; view, change, or delete data.

RECOMMENDATIONS:

We recommend the following actions be taken:

  • Apply appropriate patches provided by Apple to vulnerable systems immediately after appropriate testing.
  • Run all software as a nonprivileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to download, accept or execute files from untrusted and unknown sources.
  • Remind users not to visit untrusted websites or follow links provided by untrusted or unknown sources.
  • Evaluate read, write, and execute permissions on all newly installed software.
  • Apply the Principle of Least Privilege to all systems and services.
