Reports on bugs hit the iPhone. This iOS operating system bug made by Apple does not occur in all parts, but only in the WiFi connectivity section.
Two weeks ago it was mentioned that a strange bug caused their device to be unable to connect to a WiFi access point when moved.
Mashable reports, though, that the bug has a simple but inconvenient fix and can be easily avoided by not connecting to a wireless network with a symbol in its name.
But it turns out there’s another iPhone bug with almost similar characteristics, just that it’s almost impossible to avoid and harder to fix as well.
The original vulnerability involved WiFi access points or APs using the percent sign (%) in their name. In many programming languages, this symbol is used to indicate that the character that follows it is intended as a command rather than a letter to be displayed.
Somewhere in the iOS code, this can break the platform’s ability to connect to any WiFi network completely. Simply resetting the phone’s network settings got everything back to normal.
That original bug can only be triggered if the user tries to connect to such a WiFi network, something that most should be avoided in the first place, even without this bug. Unfortunately, this second exploit doesn’t even require any user interaction.
According to the same security researcher who publicly disclosed the first bug, even being within range of a network named “%secretclub%power” is enough to lose all WiFi functionality and the ability to connect to WiFi networks.
iPhones can still be repaired, but it’s not as simple as resetting network settings. The user should reset the phone completely or restore from a backup if available. One could actually still try to back up their iPhone while in this state, but they would also have to manually edit the backup network list to remove the offending AP name.
The first iPhone WiFi bug was more of a nuisance waiting for careless users. However, this second one is a severe security bug that can be exploited by anyone with control over a WiFi router or hotspot.
So far, Apple has remained silent on the matter, but this new bug could prompt it to at least acknowledge it and promise a fix soon.
In the future, Apple is expected to be able to fix this iOS bug, so that similar problems will not appear again in the future
