Windows Scripting Host (WSH) in Windows 10 versions 1703 and 1709 and Windows Server, version 1709 allows a Device Guard security feature bypass vulnerability due to the way objects are handled in memory, aka "Windows Security Feature Bypass Vulnerability".

The remote Windows host is missing security update 4074592.
It is, therefore, affected by multiple vulnerabilities :

  - An vulnerability exists within microprocessors utilizing     speculative execution and indirect branch prediction,     which may allow an attacker with local user access to     disclose information via a side-channel analysis.
    (CVE-2017-5715, CVE-2017-5753, CVE-2017-5754)

  - 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-2018-0866)

  - A security feature bypass vulnerability exists in     Windows Scripting Host which could allow an attacker to     bypass Device Guard. An attacker who successfully     exploited this vulnerability could circumvent a User     Mode Code Integrity (UMCI) policy on the machine.
    (CVE-2018-0827)

  - An information disclosure vulnerability exists when the     Windows kernel improperly handles objects in memory. An     attacker who successfully exploited this vulnerability     could obtain information to further compromise the users     system.  (CVE-2018-0757, CVE-2018-0829, CVE-2018-0830)

    (CVE-2018-0847)

  - A remote code execution vulnerability exists in     StructuredQuery when the software fails to properly     handle objects in memory. An attacker who successfully     exploited the vulnerability could run arbitrary code in     the context of the current user. If the current user is     logged on with administrative user rights, an attacker     could take control of the affected system. An attacker     could then install programs; view, change, or delete     data; or create new accounts with full user rights.
    (CVE-2018-0825)

  - A security feature bypass vulnerability exists when     Microsoft Edge improperly handles requests of different     origins. The vulnerability allows Microsoft Edge to     bypass Same-Origin Policy (SOP) restrictions, and to     allow 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.  (CVE-2018-0771)

  - 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.
