Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4054523 or cumulative update 4054520. It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists in RPC if the server has Routing and Remote Access enabled. An attacker who successfully exploited this vulnerability could execute code on the target system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
(CVE-2017-11885)

- A remote code execution vulnerability exists in the way the scripting engine handles 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-2017-11894, CVE-2017-11912)

- An information disclosure vulnerability exists when Internet Explorer improperly handles objects in memory.
An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2017-11887, CVE-2017-11906)

- An information disclosure vulnerability exists when the Windows its:// protocol handler unnecessarily sends traffic to a remote site in order to determine the zone of a provided URL. This could potentially result in the disclosure of sensitive information to a malicious site.
(CVE-2017-11927)

- A remote code execution vulnerability exists when Internet Explorer improperly accesses 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-2017-11886, CVE-2017-11890, CVE-2017-11901, CVE-2017-11903, CVE-2017-11907, CVE-2017-11913)
