CVE-2016-3325

Vulnerability

This vulnerability affects Microsoft Internet Explorer 11 and Microsoft Edge. It allows a remote attacker to obtain sensitive information via a specially crafted website that, when visited by a user, triggers an information disclosure. The issue arises from improper handling of zone and integrity settings, cross-origin content, or objects in memory in the browsers [1][2]. Affected versions are those prior to the cumulative updates MS16-104 and MS16-105.

Exploitation

An attacker must host a malicious website and convince a user to visit it (typically through social engineering). No special authentication or network position is required beyond typical web browsing. The attacker can craft the site to exploit the flaw, potentially reading sensitive information from the user's browser session [1][2].

Impact

Successful exploitation allows the attacker to obtain sensitive information from the user's browser, such as data from other web pages or the system. The impact is limited to information disclosure; this vulnerability does not allow code execution or privilege escalation [1][2].

Mitigation

Microsoft released security updates as part of MS16-104 for Internet Explorer and MS16-105 for Microsoft Edge on September 13, 2016. Users should apply the cumulative updates (KB3183038 for IE, KB3183043 for Edge) to address this vulnerability. No workarounds are documented; applying the updates is the recommended mitigation [1][2].
