The latest version of the Unc0ver jailbreak leverages a vulnerability that Apple said had been exploited before it released a patch in January.
Jailbreaks remove restrictions and give users greater control over their iPhone or iPad. The developers of the jailbreak named Unc0ver recently announced the availability of version 6.0.0, which they claim works on all versions of iOS between 11.0 and 14.3 on many iPhones and iPads, including the iPhone 12 Pro launched a few months ago.
Unc0ver developers say the jailbreak is “designed to be stable” and it preserves the security layers implemented by Apple.
Unc0ver does not work on devices running iOS 14.4. That version of the operating system, released by Apple in late January, patches CVE-2021-1782, a kernel vulnerability that can be exploited for privilege escalation.
CVE-2021-1782 is one of the three vulnerabilities that Apple said “may have been actively exploited” at the time when it released the patches. All three flaws had been reported to Apple by an anonymous researcher. The tech giant has not made public any information regarding the attacks exploiting these vulnerabilities.
The developers of the Unc0ver jailbreak said on Twitter that they wrote their “own exploit based on CVE-2021-1782 for unc0ver to achieve optimal exploit speed and stability.”
