Vulnerability Details
The official description of this vulnerability states that Microsoft Internet Explorer 9 through 11 allows remote attackers to determine the existence of files via crafted JavaScript code, known as the "Internet Explorer Information Disclosure Vulnerability." The CVSS score of 4.3 indicates a medium severity level, with a low attack complexity and no privileges required for exploitation. The vulnerability affects Internet Explorer across multiple Windows operating systems.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of JavaScript by Internet Explorer. Attackers can exploit this flaw through network-based attacks that require user interaction to trigger the malicious JavaScript. The attack vector is considered to be of low complexity, as it does not require any special privileges or advanced knowledge to execute.
The impact on confidentiality is low, as it only allows file existence detection rather than direct access to the files themselves. There are no impacts on integrity or availability, as the vulnerability does not alter or disrupt the functionality of affected systems.
Risk & Impact Analysis
The real-world risk associated with CVE-2016-0162 includes potential information disclosure that could be leveraged by attackers to plan further intrusions. Given that this vulnerability is present in widely used versions of Internet Explorer, the blast radius is significant, potentially affecting numerous organizations still utilizing these versions.
Organizations should assess their usage of affected Internet Explorer versions and incorporate necessary updates in their patch management cycles. The urgency of addressing this vulnerability is heightened by its inclusion in the KEV catalog, indicating active awareness and risk to organizations that fail to act.
