A wi-fi community naming bug has been found in Apple’s iOS working system that successfully disables an iPhone’s capacity to connect with a Wi-Fi community.
The problem was noticed by safety researcher, who discovered that the cellphone’s Wi-Fi performance will get completely disabled after becoming a member of a Wi-Fi community with the bizarre title “%ppercentspercentspercentspercentspercentn” even after rebooting the cellphone or altering the community’s title (i.e., service set identifier or SSID).
The bug may have severe implications in that dangerous actors may exploit the problem to plant fraudulent Wi-Fi hotspots with the title in query to interrupt the system’s wi-fi networking options.
After becoming a member of my private WiFi with the SSID “%ppercentspercentspercentspercentspercentn”, my iPhone completely disabled it is WiFi performance. Neither rebooting nor altering SSID fixes it :~)

The problem stems from abug within the method iOS parses the SSID enter, triggering a denial of service within the course of, in keeping with Zhi Zhou, a senior safety engineer at Ant Monetary Gentle-Yr Safety Labs in a brief evaluation revealed on Saturday.
“For the exploitability, it does not echo and the remainder of the parameters do not appear to be to be controllable. Thus I do not assume this case is exploitable,” Zhou. “In any case, to set off this bug, it’s worthwhile to hook up with that WiFi, the place the SSID is seen to the sufferer. A phishing Wi-Fi portal web page may as properly be more practical.”
Whereas the problem is not, iPhones which have been affected by the issue would wish to have their iOS community settings reset by going to Settings > Normal > Reset > Reset Community Settings and ensure the motion.
