TIBCO Security Advisory: April 9, 2008 - TIBCO Rendezvous®

TIBCO Rendezvous® vulnerability

Original release date: April 9, 2008
Last revised: --
CVE-2008-1703
Source: TIBCO Software Inc.

Description

TIBCO Rendezvous and derived components listed below contain buffer overflow vulnerabilities in the processing of inbound data. The impact of these vulnerabilities may include remote execution of arbitrary code, information disclosure, and denial of service.

TIBCO has released updates that address critical vulnerabilities in server and library components of TIBCO Rendezvous.

TIBCO Rendezvous and derived components contain a vulnerability that may allow an attacker to compromise the server or application by sending a specially crafted message.

TIBCO strongly recommends sites running the affected components to install the update or take mitigating action as appropriate.

Systems Affected

  • TIBCO Rendezvous versions below 8.1.0
  • TIBCO Rendezvous TX versions below 2.0.4
  • TIBCO Rendezvous DataSecurity versions below 2.1.6
  • TIBCO Runtime Agent (TRA) versions below 5.5.4
  • TIBCO Hawk versions below 4.8.0
  • TIBCO iProcess Engine versions 10.3.0 thru 10.6.1
  • TIBCO TIBCO Substation ES versions below 2.4.0
  • TIBCO Adapter for Files (z/OS only) versions below 4.4.1

The following components are affected:

  • TIBCO Rendezvous Daemon (rvd)
  • TIBCO Rendezvous Routing Daemon (rvrd)
  • TIBCO Rendezvous Secure Routing Daemon (rvsrd)
  • TIBCO Rendezvous Secure Daemon (rvsd)
  • TIBCO Rendezvous Cache (rvcache)
  • TIBCO Rendezvous Agent (rva)
  • TIBCO Rendezvous Relay Agent (rvrad)
  • TIBCO Rendezvous Performance Test Tool (rvperfm, rvperfs)
  • TIBCO Rendezvous client library (libtibrv)
  • TIBCO Rendezvous Server In-Process Module Add-on (libtibrvipm)
  • TIBCO Rendezvous Access Control List Daemon (rvacld)
  • TIBCO Rendezvous TX daemon (rvtxd)
  • TIBCO iProcess Engine Process Sentinal (procmgr, pmsulib)
  • TIBCO Substation ES RV Transformer (tibssxfr)
  • TIBCO File Adapter (z/OS) Publisher (sxf3rpub)
  • TIBCO File Adapter (z/OS) Subscriber (sxf3rsub)

Impact

The impact of these vulnerabilities varies depending on the operating system and the privilege levels of the user that invokes the server or application.

On Unix based systems, a successful exploit against the Rendezvous communication daemons (rvd, rvrd, rvsd, rvsrd) 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 Unix based systems, a successful exploit against all other components will allow arbitrary code execution with the privileges of the user that invoked the server or application.

On Windows based systems, a successful exploit will allow arbitrary code execution with the privileges of the user that invoked the server or application. If the server or application is installed as a system service, this will result in access to system privileges.

Solution

Upgrade TIBCO Rendezvous to version 8.1.0 or above.  Update all components derived from TIBCO Rendezvous to use version 8.1.0 or above.  This is strongly recommended.

If an upgrade is not possible, the following actions can mitigate the vulnerabilities:

  • Utilize a firewall to restrict UDP/PGM access to the Rendezvous network to trusted sources.
  • Utilize a firewall to restrict access to the Rendezvous server port to trusted sources.
  • Use a user with restricted privileges to invoke the server or application.
  • On Unix systems, invoke the server or application from a chroot environment.  This will restrict the ability to access or modify information in the event of a successful exploit.
