An information disclosure vulnerability exists when Microsoft Word improperly discloses the contents of its memory. An attacker who exploited the vulnerability could use the information to compromise the user’s computer or data. To exploit the vulnerability, an attacker could craft a special document file and then convince the user to open it. An attacker must know the memory address location where the object was created. The update addresses the vulnerability by changing the way certain Word functions handle objects in memory.

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

  - An information disclosure vulnerability exists when     Microsoft Word improperly discloses the contents of its     memory. An attacker who exploited the vulnerability     could use the information to compromise the user’s     computer or data.  (CVE-2020-1502)

  - An information disclosure vulnerability exists when     Microsoft Word 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-2020-1503, CVE-2020-1583)

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

  - 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-2020-1494,     CVE-2020-1495, CVE-2020-1496)

  - 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-2020-1497)

  - An information disclosure vulnerability exists when Microsoft Word 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-2020-1503, CVE-2020-1583)

  - A remote code execution vulnerability exists in Microsoft Office 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-2020-1563)

  - An elevation of privilege vulnerability exists in the way that Microsoft Office Click-to-Run (C2R)     components handle objects in memory. An attacker who successfully exploited the vulnerability could     elevate privileges. The attacker would need to already have the ability to execute code on the system.
    (CVE-2020-1581)

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

- A spoofing vulnerability exists when Microsoft SharePoint Server does not properly sanitize a specially crafted web request to an affected SharePoint server.

- An information disclosure vulnerability exists when Microsoft SharePoint Server 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 Office product installed on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists when     Microsoft Word 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-2020-1503, CVE-2020-1583)

  - 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-2020-1495, CVE-2020-1498)

The Microsoft Office Online Server or Microsoft Office Web Apps installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - 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.

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

  - 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-2020-1499,     CVE-2020-1500, CVE-2020-1501)

  - An information disclosure vulnerability exists when     Microsoft SharePoint Server fails to properly handle     objects in memory. An attacker who successfully     exploited this vulnerability could obtain information to     further compromise the users system.  (CVE-2020-1505)

  - An information disclosure vulnerability exists when     Microsoft Word 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-2020-1502, CVE-2020-1503,     CVE-2020-1583)
