IOS exposed a new vulnerability: attackers can bypass passwords to protect access contact information.

According to a message published on Thursday of the iPhone islam.com, a foreign website cracked, the website found a new vulnerability in Apple iOS 5.0.1 this week, attackers can bypass the password protection of the iPhone and access the contact list and call records in the target iPhone address book without authorization.

According to iPhone Islam, the method to exploit this vulnerability is complicated and requires multiple SIM card insertion and removal, alternatively, bypass password protection by dialing an unclaimed call in an area that is not covered by the network, which is suitable for upgrading the iPhone 4S to iOS5.0.1, iPhone 4 and iPhone 3GS

Unlike the previous iOS security vulnerability, the process of exploiting this vulnerability requires a lot of complex operations, and requires the attacker to know the mobile phone number of the target iPhone or have a backup SIM card. IPhone Islam rated this vulnerability as an "important" vulnerability, but some people think it is only a small problem. Apple may solve this problem when releasing the iOS 5.1 operating system.
