The team that develops unc0ver has published the tool, as we saw a few days ago. This software, which already reaches version 5.0.1, allows jailbreaking to all iOS devices with any version, including the recently released iOS 13.5.
A zero-day exploit, the reason for this new jailbreak
This tool uses a zero-day Kernel vulnerability that was discovered by Pwn20wnd in a process that, curiously, is in charge of maintaining the security of the application sandbox. Exploiting this vulnerability allows apps that are not signed by Apple to run and therefore full access to the device’s file system.
From a security point of view, we could say, between considerable quotes, that it is a more secure jailbreak since it does not jump alerts on the use of device resources and respects the application sandbox. As with other similar tools, its use is strongly discouraged, which should be reserved only for security researchers or developers focused on software audits.
Interest in the jailbreak has been plummeting for several years. So much so that the creator developer of Cydia, the famous alternative App Store, closed the store a while ago. Little by little, in addition, Apple is providing more and more options and functions to its operating system, so the jailbreak, especially to install modifications, is losing meaning.
Surely in the next few days we will see an iOS 13.5.1 version or similar appear in which Apple fixes this error. While we wait for a response from the Cupertino company, one thing is clear: We should never purposely undermine the security of our devices.
