Last revised:
CVE-2019-8990
Source: TIBCO Software Inc.

Systems Affected

  • TIBCO ActiveMatrix BusinessWorks versions 6.4.2 and below

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.
