TIBCO Security Advisory: February 13, 2019 - TIBCO Silver Fabric
- TIBCO Silver Fabric versions 5.8.1 and below
The following component is affected:
- SOAP Admin API
The component listed above contains a vulnerability that may allow reflected cross-site scripting (XSS) attacks.
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)
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:
<servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>/webservices/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>/WebServices/*</url-pattern> </servlet-mapping>
TIBCO would like to extend its appreciation to Robert Podsiadlo of ING Tech Poland for discovery of this vulnerability.
