"The Microsoft Dynamics 365 (on-premises) is missing security updates. It is, therefore, affected by multiple
vulnerabilities:

  - 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-2020-1221, CVE-2020-1591)");
