Permissions, Privileges, and Access Controls
WebKit in Apple iOS before 4 on the iPhone and iPod touch does not enforce the expected boundary restrictions on content display by an IFRAME element, which allows remote attackers to spoof the user interface via a crafted HTML document.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
