TIBCO Security Advisory: January 15, 2008 - TIBCO SmartSockets®

TIBCO SmartSockets® vulnerability

Original release date: January 15, 2008
Last revised: --
CVE-2007-5655, CVE-2007-5656, CVE-2007-5657, CVE-2007-5658
Source: TIBCO Software Inc.

Description

TIBCO SmartSockets 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 which address critical vulnerabilities in the server and library components of the TIBCO SmartSockets.

These vulnerabilities directly affect the SmartSockets server (rtserver) and applications utilizing the TipcConnAccept interface. These vulnerabilities may also affect applications utilizing the SmartSockets libraries if an attacker is able to inject data into the server/client TCP connection.

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

Systems Affected

  • TIBCO SmartSockets versions below 6.8.1

The following components are affected:

  • TIBCO SmartSockets Server (rtserver)
  • TIBCO SmartSockets Cache (scache)
  • TIBCO SmartSockets Gateway (rtgateway)
  • TIBCO SmartSockets LiveWeb (rtweb)
  • TIBCO SmartSockets client libraries (rtipc, rtmsg, rtutil)
  • TIBCO SmartMQ Server (mqserver)

 

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, the successful exploit will allow arbitrary code execution with the privileges of the user that invoked the server or application.

On Windows based systems, the 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 SmartSockets to version 6.8.1 or above.  This is strongly recommended.

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

  • Utilize a firewall to restrict access to the rtserver or TipcConnAccept 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.
