Pwn20wnd, the author of the jailbreaking tool “unc0ver,” has updated their software to support iOS 14.3 and earlier releases. The last release of the jailbreaking tool, unc0ver v6.0.0, now includes the exploit code for the CVE-2021-1782 vulnerability that Apple in January claimed was actively exploited by threat actors.
Jailbreaking an iOS mobile device it is possible to remove hardware restrictions implemented by the Apple’s operating system, Jailbreaking gives users root access to the iOS file system and manager, this allows them to download and install applications and themes from third-party stores.
Apple did not disclose info about the attacks in the wild exploiting this vulnerability.
The CVE-2021-1782 flaw is a race condition issue that resides in the iOS operating system kernel.
“A malicious application may be able to elevate privileges. Apple is aware of a report that this issue may have been actively exploited.” reads the advisory. “A race condition was addressed with improved locking.”
unc0ver v6.0.0 could be used to unlock any device running iOS 11.0 through iOS 14.3, below the announcement made by Pwn20wnd on Twitter.
We wrote our own exploit based on CVE-2021-1782 for #unc0ver to achieve optimal exploit speed and stability.

Zimperium founder, Zuk Avraham, also shared the news of the release of the jailbreaking tool and invited Apple to enable users to have full access to their devices.
Unc0ver just released a jailbreak up to iOS 14.3. Great for the community. My guess is that unc0ver leveraged the kernel vulnerability that was exploited in the wild and patched on iOS 14.4 (CVE-2021-1782). Yet another example that attackers have an edge on iOS vs. defenders.

In May 2020, the Unc0ver team released Unc0ver 5.0.0 which exploits a memory consumption issue in the kernel, tracked as CVE-2020-9859, to jailbreak mobile devices running iOS versions up to iOS v13.5.
