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, aka 'Microsoft Office SharePoint XSS Vulnerability'.

According to its self-reported version number, the Microsoft SharePoint application running on the remote host is affected by 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 a security update. It is, therefore, affected by the following vulnerabilities:

  - 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-2019-0778)

  - 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.(CVE-2019-0604)
