Multiple Vulnerabilities Discovered in Apple Products

Multiple Vulnerabilities Discovered in Apple Products

A cybersecurity alert was issued Wednesday, Oct. 30, 2019, regarding multiple vulnerabilities in Apple products. The vulnerabilities could allow an attacker to execute arbitrary code, which could potentially lead to a breach.

What It Is:
Multiple vulnerabilities have been discovered in watchOS, Safari, iOS, iPadOS, macOS Catalina, and tvOS. The most severe of these vulnerabilities could allow for arbitrary code execution.

• tvOS is an operating system for the fourth-generation Apple TV digital media player.
• iTunes is a media player, media library, online radio broadcaster, and mobile device management application developed by Apple.
• watchOS is the mobile operating system for the Apple Watch and is based on the iOS operating system.
• Safari is a web browser available for OS X.
• iPadOS is the successor to iOS 12 and is a mobile operating system for iPads.
• iOS is a mobile operating system for mobile devices, including the iPhone, iPad, and iPod touch.

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 privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

What To Do:
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 non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
• Remind users not to download, accept, or execute files from untrusted or unknown sources.
• Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources.
• Apply the Principle of Least Privilege to all systems and services.

Negative Consequences of Lost or Stolen Data:
The loss or theft of proprietary data can have severe impacts, particularly if the compromise becomes public and sensitive information is exposed. Possible impacts include:

• Temporary or permanent loss of sensitive or proprietary information.
• Disruption to regular operations.
• Financial losses incurred to restore systems and files.
• Potential harm to an organization’s reputation.
