A remote code execution vulnerability exists in Microsoft Word software when it fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted file to perform actions in the security context of the current user. For example, the file could then take actions on behalf of the logged-on user with the same permissions as the current user. To exploit the vulnerability, a user must open a specially crafted file with an affected version of Microsoft Word software. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) that contains a specially crafted file that is designed to exploit the vulnerability. However, an attacker would have no way to force the user to visit the website. Instead, an attacker would have to convince the user to click a link, typically by way of an enticement in an email or Instant Messenger message, and then convince the user to open the specially crafted file. The security update addresses the vulnerability by correcting how Microsoft Word handles files in memory.

The Microsoft Word Products are missing a security update.
It is, therefore, affected by the following vulnerability :

  - A remote code execution vulnerability exists in     Microsoft Word software when it fails to properly handle     objects in memory. An attacker who successfully     exploited the vulnerability could use a specially     crafted file to perform actions in the security context     of the current user. For example, the file could then     take actions on behalf of the logged-on user with the     same permissions as the current user.  (CVE-2020-1218)

The Microsoft Office Products are missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists when Microsoft Excel improperly discloses the contents of     its memory. An attacker who exploited the vulnerability could use the information to compromise the users     computer or data. (CVE-2020-1224)

  - A remote code execution vulnerability exists in Microsoft Excel software 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-2020-1193,     CVE-2020-1332, CVE-2020-1335, CVE-2020-1594)

  - A remote code execution vulnerability exists in Microsoft Word software when it fails to properly handle     objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted     file to perform actions in the security context of the current user. For example, the file could then take     actions on behalf of the logged-on user with the same permissions as the current user. (CVE-2020-1218,     CVE-2020-1338)

The Microsoft SharePoint Server installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in     Microsoft SharePoint when the software fails to check     the source markup of an application package. An attacker     who successfully exploited the vulnerability could run     arbitrary code in the context of the SharePoint     application pool and the SharePoint server farm account.
    Exploitation of this vulnerability requires that a user     uploads a specially crafted SharePoint application     package to an affected version of SharePoint. The     security update addresses the vulnerability by     correcting how SharePoint checks the source markup of     application packages. (CVE-2020-1200, CVE-2020-1210,     CVE-2020-1452, CVE-2020-1453, CVE-2020-1576)

  - A tampering vulnerability exists when Microsoft     SharePoint Server fails to properly handle profile data.
    An attacker who successfully exploited this     vulnerability could modify a targeted user's profile     data.  (CVE-2020-1440, CVE-2020-1523)

  - A remote code execution vulnerability exists in     Microsoft SharePoint where APIs aren't properly     protected from unsafe data input. An attacker who     successfully exploited the vulnerability could run     arbitrary code in the context of the SharePoint     application pool and the SharePoint server farm account.
    Exploitation of this vulnerability requires that a user     access a susceptible API on an affected version of     SharePoint with specially-formatted input. The security     update addresses the vulnerability by correcting how     SharePoint handles deserialization of untrusted data.
    (CVE-2020-1595)

  - A spoofing vulnerability exists when Microsoft     SharePoint Server does not properly sanitize a specially     crafted web request to an affected SharePoint server. An     authenticated attacker could exploit the vulnerability     by sending a specially crafted request to an affected     SharePoint server. The attacker who successfully     exploited the vulnerability could then perform cross-     site scripting attacks on affected systems and run     script in the security context of the current user.
    These attacks could allow the attacker to read content     that the attacker is not authorized to read, use the     victim's identity to take actions on the SharePoint site     on behalf of the user, such as change permissions and     delete content, and inject malicious content in the     browser of the user. The security update addresses the     vulnerability by helping to ensure that SharePoint     Server properly sanitizes web requests. (CVE-2020-1205)

  - A remote code execution vulnerability exists in     Microsoft SharePoint Server when it fails to properly     identify and filter unsafe ASP.Net web controls. An     authenticated attacker who successfully exploited the     vulnerability could use a specially crafted page to     perform actions in the security context of the     SharePoint application pool process.  (CVE-2020-1460)

  - A remote code execution vulnerability exists in     Microsoft Word software when it fails to properly handle     objects in memory. An attacker who successfully     exploited the vulnerability could use a specially     crafted file to perform actions in the security context     of the current user. For example, the file could then     take actions on behalf of the logged-on user with the     same permissions as the current user.  (CVE-2020-1218,     CVE-2020-1338)

  - A cross-site-scripting (XSS) vulnerability exists when     Microsoft SharePoint Server does not properly sanitize a     specially crafted web request to an affected SharePoint     server. An authenticated attacker could exploit the     vulnerability by sending a specially crafted request to     an affected SharePoint server. The attacker who     successfully exploited the vulnerability could then     perform cross-site scripting attacks on affected systems     and run script in the security context of the current     user. The attacks could allow the attacker to read     content that the attacker is not authorized to read, use     the victim's identity to take actions on the SharePoint     site on behalf of the user, such as change permissions     and delete content, and inject malicious content in the     browser of the user. The security update addresses the     vulnerability by helping to ensure that SharePoint     Server properly sanitizes web requests. (CVE-2020-1198,     CVE-2020-1227, CVE-2020-1345, CVE-2020-1482,     CVE-2020-1514)
