Multiple Vulnerabilities in Apple Products Could Allow for Arbitrary Code Execution

Multiple vulnerabilities have been discovered in Apple products, the most severe of which could allow for arbitrary code execution. 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.
Threat Intelligence Apple is aware of a report that CVE-2023-42916 and CVE-2023-42917 may have been actively exploited against versions of iOS released before iOS 16.7.1.
Systems Affected
Versions prior to macOS Sonoma 14.1.2 Versions prior to iOS 17.1.2 and iPadOS 17.1.2 Versions prior Safari 17.1.2
Risk
Government:
– Large and medium government entities: High – Small government entities: Medium
Businesses: – Large and medium business entities: High
– Small business entities: Medium
Home Users: Low
Technical Summary Multiple vulnerabilities have been discovered in Apple products, the most severe of which could allow for arbitrary code execution. Details of the vulnerabilities are as follows:
Recommendations
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. Block execution of code on a system through application control, and/or script blocking. Use capabilities to prevent suspicious behavior patterns from occurring on endpoint systems. This could include suspicious process, file, API call, etc. behavior.
