Information Disclosure Vulnerability in Microsoft IE
This new vulnerability stems from the way IE handles
VBScript when validating cross-domain access, letting one domain's scripts
access another domain's contents within a frame. An attacker can use scripts to
exploit the vulnerability by extracting other domains' frame contents to send
to the attacker's Web site. The attacker can view files located on the user's
local machine or capture the contents of third-party Web sites the user visited
after leaving the attacker's site. The vulnerability lets an intruder learn
personal information about the user, such as usernames, passwords, and credit
card information.
