A cybersecurity advisory was issued Thursday, Feb. 7, 2019, by Apple regarding multiple vulnerabilities in Apple products. These vulnerabilities could allow for arbitrary code execution.
What It Is:
Multiple vulnerabilities have been discovered in iOS, Shortcuts for iOS and macOS Mojave. The most severe of these vulnerabilities could allow for arbitrary code execution.
• macOS Mojave is a desktop and server operating system for Macintosh computers.
• Shortcuts for iOS allows for a quick way to get one or more tasks done with your apps by creating a single click multi-step shortcut.
• 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 or application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
There are currently no reports of these vulnerabilities being exploited in the wild.
What It Means:
If your business or organization use Apple products, you will need to apply the appropriate patches from Apple immediately after appropriate testing to prevent a possible security breach.
Systems Affected Include:
• macOS Mojave versions prior to 10.14.3
• iOS versions prior to 12.1.4
• Shortcuts for iOS prior to 2.1.3
• Large and medium government entities: High
• Small government entities: High
• Large and medium business entities: High
• Small business entities: High
Home users: Low
Multiple vulnerabilities have been discovered in iOS and Mojave. The most severe of these vulnerabilities could allow for arbitrary code execution. Details of these vulnerabilities are as follows:
• A logic issue existed in the handling of Group FaceTime calls. The issue was addressed with improved state management. (CVE-2019-6223)
• Multiple memory corruption issues were addressed with improved input validation. (CVE-2019-7286, CVE-2019-7287)
• The issue was addressed with improved validation on the FaceTime server. (CVE-2019-7288)
• A parsing issue in the handling of directory paths was addressed with improved path validation. (CVE-2019-7289)
• A sandboxed process may be able to circumvent sandbox restrictions. (CVE-2019-7290)
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.
