Finding a bug that can disable the Wi-Fi feature of the iPhone using only the name of a Wi-Fi network

Why my iPhone Wifi Not Working or iPhone WIFI disabled ?

A strange bug has been reported when the iPhone's Wi - Fi feature is disabled while trying to connect to the SSID, or the Wi-Fi network with the % symbol in the name, via the iPhone.

Security researcher Carl Schou reports this via a Twitter message, stating that the iOS device crashes while trying to use a Wi-Fi network called %secretclub% power.

The Verge website reports that when the Wi-Fi feature is disabled, the network settings cannot be reset or re-enabled.

A few weeks ago, Schou and his software reverse engineer team revealed that using the SSID %p%s%s%s%s%n disables Wi-Fi on iOS devices, as well as features such as AirDrop. It was revealed that it could not be done.

In most programming languages, the % sign is used to format data in variables. For example, in the C language, % n is used in a string format function to assign the number of characters in a string to another variable.

The 9to5mac website points out that if the Wi-Fi network name (SSID) is often used in the internal libraries of iOS as mentioned above, this could be a runtime error.

Presumably Apple is still working on fixing this problem, and will be able to avoid this problem by not connecting to Wi-Fi networks with % marks via iOS devices until an update is released.
