OVERVIEW:
A vulnerability has been discovered in Apple Products, which could allow for arbitrary code execution if a user views a specially crafted web page.

• 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.
• macOS Monterey is the 18th and current major release of macOS.
• Safari is a graphical web browser developed by Apple.

Successful exploitation of this vulnerability 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.

Home users: Low

TECHNICAL SUMMARY:
A vulnerability has been discovered in Apple Products, which could allow for arbitrary code execution if a user views a specially crafted web page.

Successful exploitation of this vulnerability 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 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 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.
