Permissions, Privileges, and Access Controls
Microsoft Internet Explorer 6 and 7 does not properly determine the domain or security zone of origin of web script, which allows remote attackers to bypass the intended cross-domain security policy, and execute arbitrary code or obtain sensitive information, via a crafted HTML document, aka "Event Handling Cross-Domain Vulnerability."
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.
