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 :

 - An information disclosure vulnerability exists when Skype for Business is accessed via Internet Explorer. An attacker who exploited the vulnerability could cause the user to place a call without additional consent, leading to information disclosure of the user profile. For the vulnerability to be exploited, a user must click a specially crafted URL that prompts the Skype app.
 (CVE-2020-1432)

 - A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory. 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-2020-1403)

Microsoft has released the following security updates to address this issue:
