  Original release date: April 9, 2019
  Last revised: ---

Description

  The component listed above contains a vulnerability that theoretically allows
  unauthenticated HTTP requests to be processed by the BusinessWorks engine
  even when authentication is required. This possibility is restricted to
  circumstances where HTTP "Basic Authentication" policy is used in conjunction
  with an XML Authentication resource. The BusinessWorks engine might instead
  use credentials from a prior HTTP request for authorization purposes.


Impact

  The impact of this vulnerability includes the possibility of a malicious
  HTTP client successfully executing HTTP requests without authenticating.
  This possibility is restricted to circumstances where HTTP basic
  authentication is used in conjunction with an XML Authentication resource.
