Affected Products and Versions

IBM Platform Symphony 6.1.1, 7.1 Fix Pack 1, and 7.1.1, and IBM Spectrum Symphony 7.1.2 and 7.2. All OS editions, including Linux and Windows, are affected. The remediation steps for Linux are provided in this document. For Windows, use the Linux steps as a reference and find the correct path for patching.

Remediation/Fixes

1. For IBM Platform Symphony 6.1.1 or 7.1 Fix Pack 1, download the appropriate fix and follow the instructions in the readme file to upgrade to Struts version 2.3.32.

2. For IBM Platform Symphony 7.1.1 and higher, follow the steps to update to Struts version 2.3.32 on Linux hosts:
    2.1 Log on to each management host in the cluster and download the struts-2.3.32-lib.zip package from the following location: 2.2 Stop the Platform Management Console service (WEBGUI):
      > egosh service stop WEBGUI
    2.3 For backup purposes, move the following files, which will be replaced by new files:

      NOTE: If you changed the default configuration for the WLP_OUTPUT_DIR environment variable and the APPEND_HOSTNAME_TO_WLP_OUTPUT_DIR parameter is set to true in the $EGO_CONFDIR/wlp.conf file, you must clean up the $WLP_OUTPUT_DIR/webgui_hostname/gui/workarea/ directory.
    2.6 Launch a web browser and clear your browser’s cache.
    2.7 Start the WEBGUI service:
      > egosh service start WEBGUI
