An information disclosure vulnerability exists when the Windows its:// protocol handler unnecessarily sends traffic to a remote site in order to determine the zone of a provided URL. This could potentially result in the disclosure of sensitive information to a malicious site.
To exploit the vulnerability an attacker would have to trick a user into browsing to a malicious website or to an SMB or UNC path destination. An attacker who successfully tricked a user into disclosing the userβs NTLM hash could attempt a brute-force attack to disclose the corresponding hash password.
The security update addresses the vulnerability by correcting how the Windows its:// protocol handler determines the zone of a request.
