"The Microsoft Dynamics 365 (on-premises) is missing a
security update. It is, therefore, affected by the following
vulnerability :

  - A cross site scripting vulnerability exists when
    Microsoft Dynamics 365 (on-premises) does not properly
    sanitize a specially crafted web request to an affected
    Dynamics server. An authenticated attacker could exploit
    the vulnerability by sending a specially crafted request
    to an affected Dynamics 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
    authenticated 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 within Dynamics Server 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 Dynamics Server properly sanitizes web
    requests. (CVE-2019-1375)");
