Attacking locally is a requirement. Furthermore, an exploit is available. There are still doubts about whether this vulnerability truly exists.

Detailsinfo

A vulnerability, which was classified as critical, was found in Apple iOS up to 12 (Smartphone Operating System). This affects an unknown code of the component Erase. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, integrity, and availability.

The weakness was published 06/22/2018 by Hacker Fantastic as not defined tweet (Twitter). The advisory is shared at twitter.com. The public release happened without involvement of Apple. An attack has to be approached locally. No form of authentication is needed for exploitation. Technical details are unknown but a private exploit is available. The price for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 03/16/2020). It is expected to see the exploit prices for this product increasing in the near future.MITRE ATT&CK project uses the attack technique T1068 for this issue. The advisory points out:

IOS has a glitch in the UI when pins are sent as duplicates or too quickly, to prevent accidental pin entry these pins are never tested by the device. This video showed what was original believed to be a bypass exploit for the erase data function, however the SEP is not actually processing the majority of the input PIN's due to the aforementioned feature in IOS. So although the device appears to process multiple pins sent at once, it in fact only processes a smaller number of inputs. This means the bypass attack isn't valid as it only appears that those pins were tested.

A private exploit has been developed by Hacker Fantastic. It is declared as proof-of-concept. The real existence of this vulnerability is still doubted at the moment.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at SecurityTracker (ID 1041177†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
