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

 - An authentication bypass vulnerability exists in Windows Communication Foundation (WCF) and Windows Identity Foundation (WIF), allowing signing of SAML tokens with arbitrary symmetric keys.

 - 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 security updates. It is, therefore, affected by multiple vulnerabilities :

  - An authentication bypass vulnerability exists in Windows     Communication Foundation (WCF) and Windows Identity     Foundation (WIF), allowing signing of SAML tokens with     arbitrary symmetric keys. This vulnerability allows an     attacker to impersonate another user, which can lead to     elevation of privileges. The vulnerability exists in     WCF, WIF 3.5 and above in .NET Framework, WIF 1.0     component in Windows, WIF Nuget package, and WIF     implementation in SharePoint. An unauthenticated     attacker can exploit this by signing a SAML token with     any arbitrary symmetric key. This security update     addresses the issue by ensuring all versions of WCF and     WIF validate the key used to sign SAML tokens correctly.
    (CVE-2019-1006)

  - 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-2019-1134)
