    TIBCO Hawk® vulnerability

    Original release date: July 29, 2008
    Last revised: --
    CVE-2008-3338
    Source: TIBCOSoftware Inc.


    TIBCO Hawk vulnerability

    Original release date: July 29, 2008
    Last revised: --
    Source: TIBCO Software Inc.


    Systems Affected

    TIBCO Hawk versions below 4.8.1
    TIBCO Runtime Agent (TRA) versions below 5.6.0
    TIBCO iProcess Engine versions 10.3.0 thru 10.6.2, and 11.0.0
    TIBCO Mainframe Service Tracker versions below 1.1.0

    The following components are affected:

    * TIBCO Hawk AMI C library (libtibhawkami)
    * TIBCO Hawk HMA (tibhawkhma)


    Overview

    TIBCO Hawk and derived components listed above 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.


    I. Description

    TIBCO has released updates which address critical vulnerabilities in the
    The Hawk AMI C library and Hawk Monitoring Agent.

    The TIBCO Hawk AMI C library and derived components contain a vulnerability
    that may allow an attacker to compromise an 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.


    II. Impact

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

    On Unix based systems, a successful exploit will allow arbitrary code
    execution with the privileges of the user that invoked the application.

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


    III. Solution

    Upgrade TIBCO Hawk to version 4.8.1 or above. Update all components
    derived from TIBCO Hawk to use version 4.8.1 or above. This is strongly
    recommended.

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

    * If TIBCO Rendezvous is being used as the Hawk transport, utilize a
    firewall to restrict UDP/PGM access to the TIBCO Rendezvous network
    to trusted sources.
    * If TIBCO Enterprise Messaging Service is being used as the Hawk
    transport, ensure that authorization is enabled in the EMS server and
    that only fully trusted users are allowed to publish on Hawk subjects.
    * Use a user with restricted privileges to invoke the application.
    * On Unix systems, set the permissions of the tibhawkhma executable
    such that it is not suid.
    * On Unix systems, invoke the application from a chroot environment.
    This will restrict the ability to access or modify information in the
    event of a successful exploit.
