Internet Explorer Zero Day Report

With a search engine as prevalent as Internet Explorer (IE) is in every modern organization, focusing on this common browser should be standard practice in all risk mitigation efforts. Since IE cannot be removed from Microsoft Windows, every windows host in the world is potentially susceptible to IE vulnerabilities and attacks. This report helps analysts and management better understand the organization’s attack surface and overall risk.

In this report, the tables listing installed versions of IE can be used to assist analysts in discovering which hosts may have outdated or unsupported versions. These outdated versions should be upgraded immediately. After discovering all of the installed IE versions in the environment, analysts can use the IE-related vulnerability information to identify the current risk and assess the actions that need to be taken to reduce that risk.

For analysts seeking to address the most critical threats related to IE, the chapter on IE vulnerabilities that allow for remote code execution is a perfect start. The vulnerabilities presented there are an immense risk, as they can allow an attacker to execute code remotely, bypassing most other environmental security measures.

The report is available in the SecurityCenter Feed, a comprehensive collection of dashboards, reports, Assurance Report cards and assets. The report can be easily located in the SecurityCenter Feed under the category Discovery & Detection.

The report requirements are:

• Tenable.sc 5.5.2
• Nessus 8.6.0
