Microsoft CVE-2017-0049: Internet Explorer Information Disclosure Vulnerability



An information disclosure vulnerability exists when Internet Explorer does not properly handle JavaScript. The vulnerability could allow an attacker to detect specific files on the user's computer. In a web-based attack scenario, an attacker could host a website used to attempt to exploit the vulnerability. In addition, compromised websites and websites that accept or host user-generated content could contain specially crafted content that could exploit the vulnerability. In all cases, however, an attacker would have no way to force a user to view the attacker-controlled content. Instead, an attacker would have to convince users to take action. For example, an attacker could trick users into clicking a link that takes them to the attacker's site. An attacker who successfully exploited the vulnerability could potentially read data that was not intended to be disclosed. Note that the vulnerability would not allow an attacker to execute code or to elevate a user’s rights directly, but the vulnerability could be used to obtain information in an attempt to further compromise the affected system. The security update addresses the vulnerability by helping to restrict what information is returned to Internet Explorer.
