TIBCO Enterprise Message Service vulnerability
Original release date: April 28, 2009
Last revised: --
Source: TIBCO Software Inc.
Systems Affected
TIBCO Enterprise Message Service (EMS) versions 4.0.0 through 5.1.1
The following components are affected:
* TIBCO EMS Server (tibemsd)
Overview
The TIBCO EMS server contains a buffer overflow vulnerability in
processing of inbound data via SmartSockets. The impact of this
vulnerability may include remote execution of arbitrary code,
information disclosure, and denial of service.
I. Description
TIBCO has released an update which addresses a critical vulnerability
in the server component of TIBCO EMS when used in conjunction with
TIBCO SmartSockets.
This vulnerability affects the EMS server if an attacker controls the
SmartSockets Server, or is able to inject data into the TCP stream
between the SmartSockets and EMS servers.
TIBCO strongly recommends sites running the affected component to
install the update or take mitigating action as appropriate.
II. Impact
The impact of this vulnerability varies depending on the operating
system, configuration options of the server, and the privilege
levels of the user that invokes the server.
On Unix based systems, the successful exploit will allow arbitrary
code execution with the privileges of the user that invoked the
server.
On Windows based systems, the successful exploit will allow
arbitrary code execution with the privileges of the user that
invoked the server. If the server component is installed as a
system service, this will result in access to system privileges.
III. Solution
SmartSockets support in the EMS server is disabled by default.
If SmartSockets support has been enabled, upgrade TIBCO EMS to
version 5.1.2 or above. This is strongly recommended.
If an upgrade is not possible, the following actions can mitigate
the vulnerability:
* Disable SmartSockets support by setting "tibss_transports"
to "disabled" in the configuration file for the EMS server
(tibemsd.conf).
* Ensure that all SmartSockets servers specified in the
"server_names" field of the transports configuration file
(transports.conf) are fully trusted, and that injection of
data into the rtserver/tibemsd connection is prevented.
