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. 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. Two possible email attack scenarios exist for this vulnerability: • With the first email attack scenario, an attacker could send a specially crafted email message to the user and wait for the user to click on the message. When the message renders via Microsoft Word in the Outlook Preview Pane, an attack could be triggered. • With the second scenario, an attacker could attach a specially crafted file to an email, send it to a user, and convince them to open it. 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 other 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. For users who view their emails in Outlook, the Preview Pane attack vector can be mitigated by disabling this feature. The following registry keys can be set to disable the Preview Pane in Outlook on Windows, either via manual editing of the registry or by modifying Group Policy. Note Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. For information about how to edit the registry, view the &quot;Changing Keys and Values&quot; Help topic in Registry Editor (Regedit.exe) or view the &quot;Add and Delete Information in the Registry&quot; and &quot;Edit Registry Data&quot; Help topics in Regedt32.exe. Outlook 2010: HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Options DWORD: DisableReadingPane Value: 1 Outlook 2013: HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Options DWORD: DisableReadingPane Value: 1 Outlook 2016, Outlook 2019, and Office 365 ProPlus: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options DWORD: DisableReadingPane Value: 1

It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in     Microsoft Outlook 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-2019-1200)

  - A remote code execution vulnerability exists in     Microsoft Outlook 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-2019-1199)

  - An elevation of privilege vulnerability exists when     Microsoft Outlook initiates processing of incoming     messages without sufficient validation of the formatting     of the messages. An attacker who successfully exploited     the vulnerability could attempt to force Outlook to load     a local or remote message store (over SMB).

  - 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-2019-1201,     CVE-2019-1205)

  - A remote code execution vulnerability exists when the     Windows Jet Database Engine improperly handles objects     in memory. An attacker who successfully exploited this     vulnerability could execute arbitrary code on a victim     system. An attacker could exploit this vulnerability by     enticing a victim to open a specially crafted file. The     update addresses the vulnerability by correcting the way     the Windows Jet Database Engine handles objects in     memory. (CVE-2019-1155)

A Microsoft Word product is missing security updates. It is, therefore, affected by the following vulnerability :

According to its self-reported version number, the Microsoft SharePoint application running on the remote host is affected by multiple vulnerabilities :

 - An information disclosure vulnerability exists in the way Microsoft SharePoint handles session objects.

 - A remote code execution vulnerability exists in Microsoft SharePoint software when it fails to properly handle objects in memory.

 - 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.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

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 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-2019-1201,     CVE-2019-1205)

  - An information disclosure vulnerability exists in the     way Microsoft SharePoint handles session objects. A     locally authenticated attacker who successfully     exploited the vulnerability could hijack the session of     another user.  (CVE-2019-1202)

  - 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-2019-1203)
