Note that supported OS edition or version differs based on SWRC-VE/ RCVE/ ROR version. Please refer to the SWRC-VE/ RCVE/ ROR manual for the supported OS.

Note: Determining the affected product

  • In Windows
    space
    • In case of Windows Server 2003:
      space
      1. Click "Start" button and select "Control Panel", then select "Add or Remove Programs".
      2. At "Add or Remove Programs" windows, check if one of the following software is installed.
        space
        • Systemwalker Resource Coordinator Virtual server Edition Manager
        • ServerView Resource Coordinator VE Manager
        • ServerView Resource Orchestrator Manager

        If none of the above software appears on the list, the affected product is not installed, hence no need to proceed to the next step.
      3. Select the software at the previous step and Click the link "Click here for support information.". Then "Support Info" window will appear.
      4. At "Support Info" windows, check the "Version".
        If the installed version matches with one of the products listed at section "3-2", then the installed product contains the vulnerability.
    • In case of Windows Server 2008/ Windows Server 2012:
      space
      1. Click "Start" button and select "Control Panel", then click "Program and Features".
      2. At "Program and Features" window, check if one of the following software is installed.
        space
        • ServerView Resource Coordinator VE Manager
        • ServerView Resource Orchestrator Manager

        If none of the above software appears on the list, the affected product is not installed, hence no need to proceed to the next step.
      3. Select the software at the previous step and software info will be displayed at the bottom of "Program and Features" window.
      4. Check if the installed version matches with one of the products listed at section "3-2", then the installed product contains the vulnerability.
  • In Linux
    space
    1. Open a terminal
    2. Check if RCVE/ ROR is installed by executing the following command.
      #/bin/rpm -qi FJSVrcvmr
    3. Check "Version" info from the output of the command executed at the previous step.
      If the "Version" matches one of the products listed at section "3-2", then the installed product contains the vulnerability.

3-3. Workaround

  • In Windows
    space
    1. Login to SWRC-VE/ RCVE/ ROR manager server as Administrator or user account with admin privilege.
    2. Open Windows Explorer and move to the following directory.
      < SWRC-VE/ RCVE/ ROR installation path > \Manager\rails\config\initializers
      Note : < SWRC-VE/ RCVE/ ROR installation path > is the path to SWRC-VE/ RCVE/ ROR installation directory.
    3. Check if "CVE-2013-0156.rb" file exists or not.
      space
      1. If "CVE-2013-0156.rb" file exists, then the workaround method has already been performed, hence no need to proceed to the next step.
      2. If "CVE-2013-0156.rb" file does not exist, create the file using text editor, and add the following 2 lines into the file.

        ActiveSupport::CoreExtensions::Hash::Conversions::XML_PARSING.delete('symbol')
        ActiveSupport::CoreExtensions::Hash::Conversions::XML_PARSING.delete('yaml')
    4. Open a command prompt and restart SWRC-VE/ RCVE/ ROR manager service by executing the following command.

      < SWRC-VE/ RCVE/ ROR Installation path >\SVROR\Manager\bin\rcxmgrctl stop
      < SWRC-VE /RCVE /ROR Installation path >\SVROR\Manager\bin\rcxmgrctl start
  • In Linux
    space
    1. Login to RCVE/ ROR manager server as root user.
    2. Open a terminal and change directory to /opt/FJSVrcvmr/rails/config/initializers/
      #cd /opt/FJSVrcvmr/rails/config/initializers/
    3. Check if "CVE-2013-0156.rb" file exists under the directory.
      #ls -l CVE-2013-0156.rb
      space
      1. If the file exists, the workaround has already been performed. Hence no need to proceed to the next step.
      2. If the file does not exist, create CVE-2013-0156.rb and add the following 2 lines into the file.

        ActiveSupport::CoreExtensions::Hash::Conversions::XML_PARSING.delete('symbol')
        ActiveSupport::CoreExtensions::Hash::Conversions::XML_PARSING.delete('yaml')

        Below is an example of adding the 2 lines above using echo command.

        #echo "ActiveSupport::CoreExtensions::Hash::Conversions::XML_PARSING.delete ('symbol')" >> CVE-2013-0156.rb
        #echo "ActiveSupport::CoreExtensions::Hash::Conversions::XML_PARSING.delete('yaml')" >> CVE-2013-0156.rb
    4. Restart RCVE/ ROR manager service by executing the following command.

      #/opt/FJSVrcvmr/bin/rcxmgrctl stop
      #/opt/FJSVrcvmr/bin/rcxmgrctl start

    Note: Workaround method does not affect SWRC-VE/ RCVE/ ROR functionality.
