⚡ TL;DR | Go Straight to the Apple Vulnerability Report
Apple has released security updates addressing 2 exploited zero-day vulnerabilities in MacOS, iOS, iPadOS, and Safari that could lead to arbitrary code execution. If successfully exploited, these vulnerabilities could lead to arbitrary code execution with kernel privileges on targetted devices. This could in turn compromise and corrupt sensitive data or even lead to system crashes. A new report has been added to your Lansweeper installation to help you locate potentially vulnerable devices.
Apple Vulnerability CVE-2023-28206 & CVE-2023-28205
The vulnerability tracked as CVE-2023-28206 is an out-of-bounds write vulnerability in IOSurfaceAccelerator. If successfully exploited, it could allow an attacker to execute arbitrary code with kernel privileges using maliciously crafted apps. Since this is the highest level of privilege in the operating system, this would boil down to a complete device takeover.
CVE-2023-28205 is a use-after-free issue in WebKit. It could lead to arbitrary code execution if a threat actor were to trick their target into loading malicious web pages. Apple is aware that both of these vulnerabilities may have been exploited in the wild.
