He reported the vulnerabilities existing on iOS as well as MacOS. He released the POC info on the exploit to the public.

Min Zheng (Alibaba security team) root shell access achieved on iOS 11.3. Achieving root access is leading to potential jailbreak and now so much closer to iOS 11.3 Jailbreak.

Previously he has discovered a zero-day bug and a kernel bug which allows the attacker to execute unsigned code with kernel privileges in iOS 11.3 versions. These vulnerabilities affected iOS 11.2.6 and older versions, too. That means you still have a chance to jailbreak these versions and we can keep hope for iOS 11.3 jailbreak and you should prepare your device for a future jailbreak or semi-jailbreak release. It is recommended to save SHSH Blobs for iOS 11.3 version.

According to jailbreak experts it is more difficult to rooted jailbreak iOS 11.2.6 & iOS 11.2.5 than iOS 11.2, iOS 11.2.1 and iOS 11.2.2. That is because of It has many vulnerabilities in iOS 11.2 to iOS 11.2.2 versions and Apple patched those vulnerabilities by iOS 11.2.6 & iOS 11.2.5 updates. Here are the details about bug fixes in brief.

Memory corruption issue by Russ Cox of Google (CVE-2018-4082)

Russ Cox discovered the memory corruption issue arose in iOS 11.2 – iOS 11.2.2 running iPhone 5S and later, iPad Air and later, iPod touch 6th generation. This issue leads to executing arbitrary code with kernel privileges. This is the most important fact to create a jailbreak tool. However Russ Cox reported this bug to Apple and They have Patched it through the iOS 11.2.5 update. 

Memory corruption issue by Rani Idan of Zimperium zLabs Team (CVE-2018-4087/CVE-2018-4095)

Rani reported memory corruption issues which are caused to execute arbitrary code with system privileges. The problem is affected by iOS 11.2 to iOS 11.2.2 running iPhone 5S, and later, iPad Air and later, iPod touch 6th generation devices. This issue is a privilege to potential jailbreak. 

Apart from the above major issues, It has several bugs reported as follows.

CVE-2018-4090: Jann Horn of Google Project Zero

CVE-2018-4094: Mingi Cho, MinSik Shin, Seoyoung Kim, Yeongho Lee and Taekyoung Kwon of the Information Security Lab, Yonsei University

CVE-2018-4092: Stefan Esser of Antid0te AND

CVE-2018-4100: Abraham Masri (@cheesecakeufo)

CVE-2018-4085: Ret2 Systems Inc. working with Trend Micro’s Zero Day Initiative

CVE-2018-4086: Ian Haken of Netflix

CVE-2018-4096: found by OSS-Fuzz

However all these bugs are patched by iOS 11.2.5 update. It has mentioned in “About Apple security content of iOS 11.2.5.”

Even though these are patched in iOS 11.2.5 update, iOS 11.2 to iOS 11.2.2 firmware is remaining the bugs above. In that manner, it is effortless to jailbreak iOS 11.2 – iOS 11.2.2 versions. That is because there is a Sandbox escape attribute which is essential to create a jailbreak tool. So we can keep hopes about Untethered or Semi-tethered jailbreak for iOS 11.2 – iOS 11.2.2 jailbreak than iOS 11.2.5 & iOS 11.2.6.

  • Zimperium zLabs release iOS 11.2.2 Vulnerabilities

Security Researcher Rani Idan, member of the Zimperium zLabs, has published two iOS vulnerabilities which are potentially leading to Jailbreak. They have discovered the following vulnerabilities and are active on iOS 11.2 / iOS 11.2.1 and iOS 11.2.2. 

CVE-2018-4095 – Memory corruption over bluetoothd.

CVE-2018-4087 – Execution of arbitrary code on different crucial daemons.

Previously Zimperium zLab’s member Adam Donenfeld released a fully chained iOS kernel exploit (ziVA) that works on all the iOS devices running iOS 10.3.1 and it is appropriate for iOS 10.3.1 Jailbreak. 

According to Rani :
They have reported these bugs to Apple, and they have fixed it by iOS 11.2.5 update. However, Rani promised to publish more details regarding the research process and technical write up, along with the full exploit source code. He expressed his gratitude to Apple as well as the zLabs team and Nikias Bassen (@pimskeks) for the support throughout the project.

Review :
Sandbox escape is an essential part of jailbreak. If they release this as an open source code project, definitely jailbreak experts can develop this up to Jailbreak. However we recommend that you follow the below steps to get iOS 11.2 Jailbreak as soon as it was released.

Downgrade your device to iOS 11.2 – iOS 11.2.2

Save SHSH Blobs for your device

Don’t upgrade your device if you are an iOS 11.2.2 or below user

  • Russ Cox’s kernel exploit

According to rumors :
Security Researcher Russ Cox who works for Google has found the new Kernel Exploit for iOS 11.2. As once Ian beer released iOS 11 – iOS 11.1.2 exploit many jailbreak tools arrived for iOS 11, everyone expects it will hit iOS 11.2 Jailbreak using this kernel exploit.

According to Russ Cox Kernel exploit support list, it will work on iPhone 5S and later, iPad Air and later, iPod touch 6 devices running iOS 11.2, iOS 11.2.1 & iOS 11.2.2. Therefore, some jailbreak experts advise you to get ready for iOS 11.2 to iOS 11.2.2 jailbreak.

In addition to that rumors says, Russ Cox did not release the exploit to the public yet and informed via the official Twitter account that he has planned to release the kernel exploit to the public soon.

According to Russ Cox :
However, Russ Cox said he did not release any kernel exploit and he just reported the bugs only. Here is the screenshot of his tweet.

Review :
He is absolutely right and we can find that from Apple’s Security content. Apple patched this vulnerability in iOS 11.2.5 which was discovered from iOS 11.2. Here is the Screenshot of Apple’s security content of iOS 11.2.5.

However, there is still the chance to Jailbreak the iOS 11.2 because that bug remains same for the iOS 11.2 versions hence this was patched in iOS 11.2.5.

Whatsoever it is advisable staying on iOS 11.2 – iOS 11.2.2 versions than updating to iOS 11.2.5.

  • Kernel level async_awake exploit

This tfp0 exploit was discovered by Google security researcher Ian beer for Google’s Project Zero. That exploit was released for the iOS 11 and higher versions for the 1st time and many developers released Jailbreak tools for iOS 11 & higher versions using this exploit.

This time many hackers are busy with releasing untethered or Semi-tethered Jailbreak for iOS 11.2 to iOS 11.2.2 using this exploit.
