ZecOps Research Team releases iOS 12.1.3 PoC vulnerability

ZecOps Analysis Group releases iOS 12.1.Three PoC vulnerability

ZecOps Analysis Group simply launched a proof-of-concept for an iOS 12.1.Three vulnerability. Right here’s all it is advisable to find out about it.


Based on iOS 12.1.4’s safety content material, CVE-2019-7286 is a privilege escalation bug reliant on reminiscence corruption within the Basis framework. It may probably enable an software to realize elevated privileges.

Clement Lecigne of Google Risk Evaluation Group, Ian Beer and Samuel Groß of Google Mission Zero have been the primary to find and report it to Apple’s safety crew.

ZecOps, a safety analysis agency based by the world-renowned safety knowledgeable Zuk Avraham, subsequently detected this vulnerability and made it public.

Per Ben Hawkes, hackers have already exploited CVE-2019-7286 in addition to CVE-2019-7287 bugs as zero-day.

The researchers at ZecOps utilized binary diffing (a way used to reverse-engineer software program patches) to detect adjustments in iOS binaries.

After performing preliminary exams with the Basis framework utilizing Diaphora, the crew discovered no important adjustments within the iOS 12.1.4’s binaries as in comparison with these of iOS 12.1.3.


The researchers then moved onto the CoreFoundation framework, which revealed fairly just a few variations in binaries. This allowed them to detect minor adjustments within the cfprefsd daemon that paved the way in which for additional analysis.     

Additional, ZecOps reproduced the CVE-2019-7286 vulnerability utilizing the proof-of-concept code given under.


When working on the iOS 12.0.1 working system, it resulted in a cfprefsd daemon crash.


Based on ZecOps, this vulnerability is of crucial severity. Thankfully for us, it may show to be an important part of an iOS 12.1.Three jailbreak chain.

Hackers can use it to develop persistent exploits that stay in a purposeful state even after the person restarts the Apple system.

This implies that it may presumably result in an untethered jailbreak device for iOS 12.1.Three and under.


With that being mentioned, a full jailbreak device would nonetheless require a dependable root entry vulnerability that may get task_for_pid(0) patch on iOS 12.1.3.

Whereas we’re actually nearer to a full-fledged iOS 12.1.Three jailbreak now than ever earlier than, we nonetheless have a protracted method to go.
