    TIBCO ActiveMatrix BusinessWorks Fails To Properly Enforce Authentication

    Original release date: April 9, 2019
    Last revised: ---
    Source: TIBCO Software Inc.


    Systems Affected

    TIBCO ActiveMatrix BusinessWorks versions 6.4.2 and below

    The following component is affected:

    * HTTP Connector


    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.

    CVSS v3 Base Score: 9.1 CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N


    Solution

    TIBCO has released updated versions of the affected systems which address
    these issues.

    TIBCO ActiveMatrix BusinessWorks versions 6.4.2 and below
    update to 6.5.0 or higher
