Synopsis
The Microsoft Sharepoint Server installation on the remote host is affected by multiple vulnerabilities.Description
The Microsoft Sharepoint Server installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :- 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-2019-0668)
- A spoofing vulnerability exists in Microsoft SharePoint when the application does not properly parse HTTP content. An attacker who successfully exploited this vulnerability could trick a user by redirecting the user to a specially crafted website. The specially crafted website could either spoof content or serve as a pivot the chain an attach with other vulnerabilities in web services. (CVE-2019-0670)
- 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 versions of SharePoint. The security update addresses the vulnerability by correcting how SharePoint checks the source markup of application packages. (CVE-2019-0594, CVE-2019-0604)
