    Title : Security Vulnerabilities in MediaBase Apache and PHP
    Number : 20030502-01-I
    Date : May 19, 2003
    Reference: Kasenna Support Issue # 1095 and # 1330
    Fixed in : Patches from Kasenna Support Website
    ______________________________________________________________________________

    - -----------------------
    - --- Issue Specifics ---
    - -----------------------

    It's been reported that Kasenna Mediabase has insecure versions of
    Apache and PHP.

    SGI has investigated the issue and recommends the following steps for
    neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures
    be implemented on ALL vulnerable SGI systems.

    These issues have been corrected with patches and in future releases of
    MediaBase.

    - --------------
    - --- Impact ---
    - --------------

    MediaBase is an optional product from Kasenna, and is not installed by
    default on IRIX 6.5 systems.

    To determine the version of IRIX you are running, execute the following
    command:

      # /bin/uname -R

    That will return a result similar to the following:

      # 6.5 6.5.16f

    The first number ("6.5") is the release name, the second ("6.5.16f" in this
    case) is the extended release name. The extended release name is the
    "version" we refer to throughout this document.

    To see if mediabase is installed, execute the following command:

      % versions -b | grep mbase
      I mbase_client 06/01/2000 WebFORCE MediaBase 2.1 - Client
      I mbase_players 10/06/2000 SGI MediaBase 4.0.1 - Players packaged
                                          for installation on server
      I mbase_root 12/24/2000 SGI MediaBase 4.0.1 - Development ROOT
                                          Files
      I mbase_server 10/06/2000 SGI MediaBase 4.0.1 - MediaBase Server
                                          Execution Environment
      I mbase_server_spk1 12/24/2000 SGI MediaBase 4.0.1 - MediaBase Server
                                          Service Pack 1

    To determine if the version of Apache installed as part of MediaBase is
    vulnerable, execute the following command:

      % /usr/kasenna/apache/bin/httpd -v
      Server version: Apache/1.3.14 (Unix)
      Server built: Dec 20 2000 15:52:52

    If the version shown (in this case 1.3.14) is lower than 1.3.27, then the
    system is vulnerable.

    To determine if the version of PHP installed as part of MediaBase is
    vulnerable, execute the following commands:

    %/usr/bin/elfdump -L /usr/mbase/asset_gateway/php_apache.so | grep TIMSTAMP
      [46] TIMSTAMP Jan 13 14:50:39 2003

    %/usr/bin/elfdump -L /usr/mbase/asset_gateway/php_mediabase.so | grep TIMSTAMP
      [45] TIMSTAMP Jan 10 14:02:48 2003

    If the value shown for "TIMSTAMP" is earlier than the ones shown, then the
    system is vulnerable.

    - ----------------------------
    - --- Temporary Workaround ---
    - ----------------------------

    There is no effective workaround available for these problems if MediaBase
    is needed. SGI and Kasenna recommend installing the patches shown below
    from the Kasenna website.

    - ----------------
    - --- Solution ---
    - ----------------

    Kasenna MediaBase is an optional product, the system is vulnerable if
    a vulnerable version of MediaBase and its associated Apache and PHP
    components are installed. Please run the commands shown in the "Impact"
    section above and install the patches if those commands show
    the system to be vulnerable.

    Kasenna has provided patches for these vulnerabilities. Our recommendation
    is to install the patches provided by Kasenna.

    To obtain the Kasenna MediaBase patches, go to http://support.kasenna.com/
    and install the patches shown in support issue 1095 (apache) and 1033 (PHP).
