Microsoft Internet Explorer external cached object DOM access

ie-cache-external-dom-access (10433)

Medium Risk

Description:

Microsoft Internet Explorer could allow a remote attacker to execute malicious JavaScript in restricted domains by using the external cached object to bypass security domain restrictions and access any page's Document Object Model (DOM). If a remote attacker creates a malicious Web page that opens a window on the attacker's own site that uses the affected cached object, but then changes the URL of the window to a victim's page, the cached object could be used to bypass restrictions and access the victim page's DOM. This vulnerability could allow an attacker to steal cookies from Web sites, gain access to Web site content, and read files or execute program's on the victim's computer.

Platforms Affected:
