Latest MS Server advisories
Medium [CVE-2020-1055] Microsoft Active Directory Federation Services Cross-Site Scripting Vulnerability
A cross-site-scripting (XSS) vulnerability exists when Active Directory Federation Services (ADFS) does not properly sanitize user inputs. An un-authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected ADFS server. The attacker who successfully exploited the vulnerability could then perform cross-site scripting attacks on affected systems and run scripts in the security context of the current user. This security update addresses the vulnerability by ensuring that ADFS properly sanitizes user inputs. Affected products named by the advisory: Windows Server 2019; Windows Server 2019 (Server Core installation); Windows Server, version 1903 (Server Core installation); Windows Server, version 1909 (Server Core installation).
Medium [CVE-2020-0963] Windows GDI Information Disclosure Vulnerability
An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage. The security update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory. Affected products named by the advisory: Windows Server 2008 R2 Service Pack 1; Windows Server 2008 R2 Service Pack 1 (Server Core installation); Windows Server 2008 Service Pack 2; Windows Server 2008 Service Pack 2 (Server Core installation); and 11 more.

Advisory [CVE-2020-1107] Microsoft SharePoint Spoofing Vulnerability
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. Affected products named by the advisory: Microsoft SharePoint Enterprise Server 2013 Service Pack 1; Microsoft SharePoint Enterprise Server 2016; Microsoft SharePoint Foundation 2013 Service Pack 1; Microsoft SharePoint Server 2019.
Advisory [CVE-2020-1105] Microsoft SharePoint Spoofing Vulnerability

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. Affected products named by the advisory: Microsoft SharePoint Enterprise Server 2016; Microsoft SharePoint Foundation 2013 Service Pack 1.

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. Affected products named by the advisory: Microsoft SharePoint Enterprise Server 2016; Microsoft SharePoint Foundation 2013 Service Pack 1; Microsoft SharePoint Server 2019.
Advisory [CVE-2020-1103] Microsoft SharePoint Information Disclosure Vulnerability
An information disclosure vulnerability exists where certain modes of the search function in Microsoft SharePoint Server are vulnerable to cross-site search attacks (a variant of cross-site request forgery, CSRF). When users are simultaneously logged in to Microsoft SharePoint Server and visit a malicious web page, the attacker can, through standard browser functionality, induce the browser to invoke search queries as the logged in user. While the attacker can’t access the search results or documents as such, the attacker can determine whether the query did return results or not, and thus by issuing targeted queries discover facts about documents that are searchable for the logged-in user. The security update addresses the vulnerability by running the search queries in a way that doesn’t expose them to this browser vulnerability. Affected products named by the advisory: Microsoft SharePoint Enterprise Server 2016; Microsoft SharePoint Foundation 2013 Service Pack 1; Microsoft SharePoint Server 2019.
