Multiple Vulnerabilities in Apple Products Could Allow for Arbitrary Code Execution

ITS Advisory Number: 
2021-057
Date(s) Issued: 
Tuesday, April 27, 2021
Subject: 
Multiple Vulnerabilities in Apple Products Could Allow for Arbitrary Code Execution
Overview: 

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.

 

THREAT INTELLIGENCE:

There are reports that WebKit Storage issues in iOS, iPadOS, Apple Watch, Apple TV 4K, and Apple TV HD may have been actively exploited. (CVE-2021-30661)

Systems Affected: 
  • iCloud for Windows prior to version 12.3
  • Xcode prior to version 12.5
  • Safari prior to version 14.1
  • macOS Big Sur prior to version 11.3
  • macOS Catalina prior to security update 2021-002
  • macOS Mojave prior to security update 2021-003
  • iOS prior to version 14.5
  • iPadOS prior to version 14.5
  • watchOS prior to version 7.4
  • tvOS prior to version 14.5
  • iTunes prior to version 12.11.3
  • GarageBand prior to version 10.4.3

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.

Actions: 
  • After appropriate testing, immediately apply patches provided by Apple to vulnerable systems.
  • 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.
