    TIBCO Silver Fabric Vulnerable to Reflected Cross-Site Scripting attacks

    Original release date: February 13, 2019
    Last revised: --
    Source: TIBCO Software Inc.


    Systems Affected

    TIBCO Silver Fabric versions 5.8.1 and below

    The following component is affected:

    * SOAP Admin API


    Description

    The component listed above contains a vulnerability that may allow reflected
    cross-site scripting (XSS) attacks.


    Impact

    The impact of this vulnerability includes the theoretical possibility that
    an unauthenticated attacker could perform administrative functions provided
    by the web interface of the affected system.

    CVSS v3 Base Score: 8.8 (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)


    Solution

    TIBCO has released updated versions of the affected component which address
    this issue.

    For each affected system, update to the corresponding software versions:

    TIBCO Silver Fabric versions 5.8.1 and below update to version 6.0.0
    or higher

    Note that the affected component has been deprecated in the systems affected.
    For customers that might not be able to update the software as quickly as
    needed, an alternate remediation is to disable the affected component. The
    component can be disabled by removing the configuration lines that activate
    it.

    To disable the affected component:
    - find the file $SF_HOME/webapps/livecluster/WEB-INF/web.xml (where
    $SF_HOME corresponds to the root folder where TIBCO Silver Fabric is
    installed.)
    - open the file in a text editor, and remove the lines that look like this:


    AxisServlet
    /webservices/*


    AxisServlet
    /WebServices/*



    Acknowledgments

    TIBCO would like to extend its appreciation to Robert Podsiadlo of ING Tech
    Poland for discovery of this vulnerability.
