New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

Synopsis
The Internet Explorer installation on the remote host is affected by multiple vulnerabilities.Description
The Internet Explorer installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :- A security feature bypass vulnerability exists when Microsoft browsers improperly handle redirect requests.
The vulnerability allows Microsoft browsers to bypass CORS redirect restrictions, and to follow redirect requests that should otherwise be ignored. An attacker who successfully exploited the vulnerability could force the browser to send data that would otherwise be restricted to a destination website of the attacker's choice. (CVE-2017-8592)
- A spoofing vulnerability exists when an affected Microsoft browser does not properly parse HTTP content.
An attacker who successfully exploited this vulnerability could trick a user by redirecting the user to a specially crafted website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services. (CVE-2017-8602)
- A remote code execution vulnerability exists in the way that the VBScript engine, when rendered in Internet Explorer, handles objects in memory. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit this vulnerability through Internet Explorer and then convince a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the Internet Explorer rendering engine. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit this vulnerability. An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. (CVE-2017-8618)
- A remote code execution vulnerability exists in the way JavaScript engines render when handling objects in memory in Microsoft browsers. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2017-8606, CVE-2017-8607, CVE-2017-8608)
- A remote code execution vulnerability exists when Internet Explorer improperly accesses objects in memory via the Microsoft Windows Text Services Framework. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2017-8594)
