Microsoft Internet Explorer URL Local Resource Access Weakness

Microsoft Internet Explorer is prone to a security weakness that may permit unauthorized access to local resources on a client computer. This will effectively bypass security restrictions implemented in Internet Explorer 6 SP1. Specifically, a malicious Web page may access a file on a vulnerable client computer by pre-pending "URL:" to a request for a specific resource.

This weakness is useful when exploiting other vulnerabilities, such as vulnerabilities that allow cross-zone access.

Exploits are known to be circulating in the wild that abuse this issue in combination with BID 10473 and one of the issues described in BID 8577.
