The Internet Explorer installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :
A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. 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-2019-0752, CVE-2019-0753, CVE-2019-0862)
An information disclosure vulnerability exists when the scripting engine does not properly handle objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2019-0835)
A tampering vulnerability exists when Microsoft browsers do not properly validate input under specific conditions. An attacker who exploited the vulnerability could pass custom command line parameters.
(CVE-2019-0764)
