Apple discloses three zero-day vulnerabilities
Target Industry
Indiscriminate, opportunistic targeting.
Overview
Apple has disclosed three zero-day vulnerabilities which, at the time of writing, have possibly been exploited in the wild. The security flaws all relate to the WebKit browser engine and are tracked as follows:
Impact
– Successful exploitation of CVE-2023-32409 allows remote threat actors to escape Web Content sandboxes.
– Successful exploitation of CVE-2023-28204 or CVE-2023-32373 could allow threat actors to gain access to sensitive data and the ability to execute arbitrary code on compromised devices.
The exploitation of the above vulnerabilities could lead to the compromise of the integrity of sensitive date contained within vulnerable devices.

Threat Landscape
Apple occupies a significant portion of the smart device and PC market share. Given that threat actors generally utilise a combination of probability and asset value to determine which attack surfaces to focus on, Apple products have become a prime target. Due to the fact that smart devices and PCs have become an integral aspect of both personal and business operations, threat actors will continue to exploit vulnerabilities contained within these systems in an attempt to extract the sensitive information contained therein.
The zero-day flaws reported on have surfaced following three additional zero-day vulnerabilities relating to Apple products that have emerged since February 2023, namely:
– CVE-2023-28206
– CVE-2023-28205
– CVE-2023-23529
Threat Group
No attribution to specific threat actors or groups has been identified at the time of writing.
