Description/symptom of problem:  

PI87300 resolves the following problem:


        Information Disclosure in WebSphere Application Server in JSF (CVE-2017-2583) 





Directions to apply fix:  
        1. Stop your Liberty profile server(s).
        2. The following files will be backed up to [LibertyRootDir]/lib/fixes automatically,
        if they exist (file locations are relative to your Liberty profile install root,
        and may not exist depending on the installed product edition or configuration of runtime):

         - lib/features/com.ibm.websphere.appserver.jsf-2.0.mf
         - dev/api/spec/com.ibm.websphere.javaee.jsf.2.0_1.0.16.jar

        3. Open a console and direct it to the location of your iFix jar
        4. Run the command "java -jar 17001-wlp-archive-IFPI87300.jar". The following launch options
        are available for the jar:

        --installLocation [LibertyRootDir] by default the jar will look for a "wlp" directory
        in its current location. If your Liberty profile install
        location is different to "wlp" and/or is not in the same
        directory as the jar then you can use this option to change
        where the jar will patch. [LibertyRootDir] can either be
        relative to the location of the jar or an absolute file path.

        --suppressInfo hides all messages other than confirming the
        patch has completed or error messages.

        5. When you next start your Liberty profile server(s), the fix will become active in your runtime.





Directions to remove fix:  
        1. Stop your Liberty profile server(s).
        2. You will need to delete the following files (file locations are
        relative to your Liberty profile install root):

         - lib/com.ibm.ws.jsf_1.0.16.cl170120170929-1533.jar
         - lib/fixes/17001-wlp-archive-IFPI87300_17.0.0001.20171012_1812.xml
         - lib/fixes/17001-wlp-archive-IFPI87300_17.0.0001.20171012_1812.lpmf
         - lib/features/com.ibm.websphere.appserver.jsf-2.0.mf
         - dev/api/spec/com.ibm.websphere.javaee.jsf.2.0_1.0.16.jar

        3. You will need to restore the static files by extracting the corresponding backup archive from
        [LibertyRootDir]/lib/fixes (contents of the backup archive are relative to your
        Liberty profile install root).

        4. When you next start your Liberty profile server(s), use the --clean option.
        The fix will then become inactive in your runtime.





Directions to re-apply fix:  
        1. Follow the instructions to apply the fix.
