CWE-ID: CWE-264

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to bypass security restrictions on the target system.

The weakness exists due to an error in the socket_create function in common/socket.c in libimobiledevice and libusbmuxd. A remote attacker can connect to an IPv4 TCP socket, bypass intended access restrictions and communicate with services on iOS devices.

Successful exploitation of the vulnerability results in security bypass.
