Apple has patched an actively exploited zero-day vulnerability (CVE-2023-37450) by releasing Rapid Security Response updates for iPhones, iPads and Macs running the latest versions of its operating systems.
The vulnerability has been discovered in Apple products, which could allow for arbitrary code execution. Successful exploitation of this vulnerability 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
- macOS Ventura prior to 13.4.1(c)
- iOS prior to 16.5.1(c)
- iPadOS prior to 16.5.1(c)
- Safari prior to 16.5.2
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.
- Train users to be aware of access or manipulation attempts by an adversary to reduce the risk of successful spearphishing, social engineering, and other techniques that involve user interaction.
