Apple has issued security patches to address zero-day vulnerabilities (CVE-2023-38606, CVE-2023-32409, and CVE-2023-37450) that have been exploited in attacks against iPhones, Macs, and iPads that seriously affect the digital security of Apple devices. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. 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. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
Affected Systems
- Safari prior to 16.6
- iOS prior to 16.6
- iPadOS prior to 16.6
- macOS Ventura prior to 13.5
- macOS Monterey prior to 12.6.8
- macOS Big Sur prior to 11.7.9
- tvOS prior to 16.6
What You Should Do
- Apply the stable channel update provided by Apple to vulnerable systems immediately after appropriate testing.
- Apply the Principle of Least Privilege to all systems and services. Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
- Restrict use of certain websites, block downloads/attachments, block Javascript, restrict browser extensions, etc.
- Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.
