This could lead to an exploitation via ROP that could let the attacker execute code that is present in the computer’s memory. The whole exploit involves escaping the sandbox, attacking the kernel and then executing an RCE, taking control of the PC. In short, NSPredicate is one of the few elements of macOS and iOS that can dynamically generate code something that was thought to be absent from Apple’s operating systems. That researcher demonstrated how when these three vulnerabilities are chained together they can allow an attacker to execute code in the context of the kernel. This chain of vulnerabilities was reported to SSD in our TyphoonPwn conference in 2019 by an independent researcher and was awarded 60,000$ USD for this discovery. We’ve gathered some of the most interesting vulnerabilities affecting iOS devices here: iOS Jailbreak via Sandbox Escape and Kernel R/W leading to RCE In a Sandbox Escape vulnerability, an attacker can execute malicious code from a sandbox outside of an environment, forcing the device to run the code within it. In 10.8 Mountain Lion, Apple introduced a new abstract class called NSUserScriptTask. A Boolean value that indicates whether the app may use access control technology to contain damage to the system and user data if an app is compromised. Even though it is known for its high level security protocols, researchers have still found a few vulnerabilities in iOS devices including some Sandbox Escape vulnerabilities.Ī Sandbox is used to provide a tightly-controlled environment where semi-trusted programs or scripts can safely run in memory. Luckily, things have gotten much better in recent releases of OS X. IOS is the well known operating system, used by a mass amount of Apple products, from iPad and iPhone to Mac and every other Apple device out there.
