"The Internet Explorer installation on the remote host is
missing security updates. It is, therefore, affected by a remote
code execution vulnerability:
- 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. If the current user is logged on with administrative user
rights, an attacker who successfully exploited the vulnerability
could take control of an affected system. An attacker could then
install programs; view, change, or delete data; or create new
accounts with full user rights. (CVE-2018-8653)");
