TIBCO Rendezvous vulnerability
Original release date: June 5, 2006
Last revised: --
Source: TIBCO Software Inc.
Systems Affected
TIBCO Rendezvous versions below 7.5.1
TIBCO Runtime Agent (TRA) versions below 5.4
TIBCO Hawk versions below 4.6.1
The following components are affected:
* TIBCO Rendezvous Routing Daemon (rvrd)
* TIBCO Rendezvous Secure Routing Daemon (rvsrd)
* TIBCO Rendezvous Secure Daemon (rvsd)
* TIBCO Rendezvous Cache (rvcache)
* TIBCO Rendezvous Agent (rva)
Overview
TIBCO Rendezvous daemon components listed above contain a buffer
overflow vulnerability in the HTTP administrative interface.
The impact of this vulnerability may include remote execution of
arbitrary code, information disclosure, and denial of service.
I. Description
TIBCO has released updates which address critical vulnerabilities
in daemon components of TIBCO Rendezvous and TIBCO Runtime Agent.
TIBCO strongly recommends sites running the affected components 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 daemon, and the privilege
levels of the user that invokes the daemon.
On Unix based systems, the successful exploit will allow arbitrary
code execution with the privileges of the user that invoked that
daemon, with the exception of user id 0 ("root"). If the daemon
component was invoked by user id 0, a successful exploit will
result in access to privileges of user id 65534 ("nobody").
On Windows based systems, the successful exploit will allow
arbitrary code execution with the privileges of the user that
invoked that daemon. If the daemon component is installed as
a system service, this will result in access to system privileges.
III. Solution
Upgrade TIBCO Rendezvous to version 7.5.1 or above. This is
strongly recommended.
If an upgrade is not possible, the following actions can mitigate
the vulnerability:
* Disable the HTTP administrative interface by use of the
"-no-http" option. This will block the vulnerability
completely.
* Set the administrative username and password of the daemon
component. This will restrict access to the vulnerability
to users possessing administrative access to the daemon
component. It is also recommended that the administration
interface be restricted to HTTPS by use of the "-https-only"
option.
* Restrict access to the HTTP administrative interface to users
on the local host by use of the "-http" and "-https" options
(example: "-http 127.0.0.1:7580 -https 127.0.0.1:7585"). This
will restrict access to the vulnerability to users with login
access to the host.
* Use a user with restricted privileges to invoke the daemon
components.
* On Unix systems, invoke the daemon components from a chroot
environment. This will restrict the ability to access or
modify information in the event of a successful exploit.
