multiple vulnerabilities :

  - A spoofing vulnerability exists in Microsoft Exchange
    Server when Outlook Web Access (OWA) fails to properly
    handle web requests. An attacker who successfully
    exploited the vulnerability could perform script or
    content injection attacks, and attempt to trick the user
    into disclosing sensitive information. An attacker could
    also redirect the user to a malicious website that could
    spoof content or the vulnerability could be used as a
    pivot to chain an attack with other vulnerabilities in
    web services.  (CVE-2019-0817, CVE-2019-0858)");
