Security Updates for Microsoft SharePoint Server and Microsoft Project Server (March 2018)

high Nessus Plugin ID 108298

Synopsis

The Microsoft SharePoint Server or Microsoft Project Server installation on the remote host is affected by multiple vulnerabilities.

Description

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

- An information disclosure vulnerability exists when Microsoft Office software reads out of bound memory due to an uninitialized variable, which could disclose the contents of memory. An attacker who successfully exploited the vulnerability could view out of bound memory. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office software. The security update addresses the vulnerability by properly initializing the affected variable. (CVE-2018-0919)

- A remote code execution vulnerability exists in Microsoft Office software when the Office 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-2018-0922)

- An elevation of privilege vulnerability exists when Microsoft SharePoint Server does not properly verify tenant permissions. 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 elevate permissions such that they gain full rights to the affected tenant. These attacks could allow the attacker to read content that the attacker is not authorized to read, change permissions, and edit or delete content. The security update addresses the vulnerability by helping to ensure that SharePoint Server properly checks tenant permissions.
(CVE-2018-0947)

- An elevation of privilege 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-2018-0909, CVE-2018-0910, CVE-2018-0911, CVE-2018-0912, CVE-2018-0913, CVE-2018-0914, CVE-2018-0915, CVE-2018-0916, CVE-2018-0917, CVE-2018-0921, CVE-2018-0923, CVE-2018-0944)
