Software version: 7.1 Fix Pack 1
Operating system(s): Linux
Reference #: 0792795
Modified date: 22 May 2019
Summary
This interim fix provides instructions on upgrading Apache Tomcat from
v6.0.43 to v8.5.37 in IBM Platform Symphony 7.1 Fix Pack 1 in order to
address security vulnerability CVE-2018-11784 in Apache Tomcat.
Vulnerability Details
CVE-ID: CVE-2018-11784

For Platform Symphony 7.1 Fix Pack 1
Installation
1. Log on to the master host as the cluster administrator and stop the
WEBGUI service:
> egosh user logon -u Admin -x Admin
> source $EGO_TOP/cshrc.platform
> egosh service stop WEBGUI
2. Log on to each management host in the cluster and back up the
following files for recovery purposes:
$EGO_TOP/gui/3.1/tomcat/
$EGO_CONFDIR/../../gui/conf/catalina.policy
$EGO_CONFDIR/../../gui/conf/catalina.properties
$EGO_CONFDIR/../../gui/conf/server.xml$EGO_TOP/gui/ego/3.1/platform/WEB-INF/web.xml
$EGO_TOP/gui/is/7.1/isgui/WEB-INF/web.xml
$EGO_TOP/gui/perf/3.1/perfgui/WEB-INF/web.xml
$EGO_TOP/gui/soam/7.1/soamgui/WEB-INF/web.xml
$EGO_TOP/gui/soam/7.1/symgui/WEB-INF/web.xml
3. Copy the apache-tomcat-8.5.37.tar.gz package to a temporary folder and
decompress the file:
> cp apache-tomcat-8.5.37.tar.gz /tmp
> tar zxvf apache-tomcat-8.5.37.tar.gz
> rm -rf apache-tomcat-8.5.37/conf/
> rm -rf apache-tomcat-8.5.37/work/
> rm -rf apache-tomcat-8.5.37/logs/
4. Copy the Tomcat folder:
> rm -rf $EGO_TOP/gui/3.1/tomcat
> cp -rf apache-tomcat-8.5.37 $EGO_TOP/gui/3.1/tomcat
5. Copy the sym7.1_lnx26-lib23-x64_build509541.tar.gz package and
decompress it:
> tar zxfo sym7.1_lnx26-lib23-x64_build509541.tar.gz -C $EGO_TOP
6. If you ran the "egoconfig mghost shared_dir" command during
installation to set up a shared location for configuration files,
ensure that the configuration file is changed in the shared directory:
> cp $EGO_TOP/gui/conf/catalina.policy
$EGO_CONFDIR/../../gui/conf/catalina.policy
> cp $EGO_TOP/gui/conf/catalina.properties
$EGO_CONFDIR/../../gui/conf/catalina.properties
> cp $EGO_TOP/gui/conf/server.xml
$EGO_CONFDIR/../../gui/conf/server.xml
7. If you modified the $EGO_CONFDIR/../../gui/conf/server.xml
configuration file for details such as the GUI service port, manually
redo those changes.
8. Edit the web.xml files to add the following configuration:
1. Edit each of the following files:
$EGO_TOP/gui/ego/3.1/platform/WEB-INF/web.xml
$EGO_TOP/gui/is/7.1/isgui/WEB-INF/web.xml
$EGO_TOP/gui/perf/3.1/perfgui/WEB-INF/web.xml
$EGO_TOP/gui/soam/7.1/symgui/WEB-INF/web.xml
$EGO_TOP/gui/soam/7.1/soamgui/WEB-INF/web.xml
2. Find the "<servlet-name>dwr-invoker</servlet-name>" line in the
"</servlet>" section and add the following configuration:
<init-param>
<param-name>crossDomainSessionSecurity</param-name>
<param-value>false</param-value>
</init-param>
For example:
<servlet>
<servlet-name>dwr-invoker</servlet-name>
<servlet-class>org.directwebremoting.servlet.DwrServlet</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>crossDomainSessionSecurity</param-name>
<param-value>false</param-value>
</init-param>
</servlet>
9. On each management host, delete all subdirectories and files in the
following directory:
> rm -rf $EGO_TOP/gui/work/*
10. On all client hosts, open your web browser and clear the browser
cache.
11. Start the WEBGUI service:
> source $EGO_TOP/cshrc.platform
> egosh service start WEBGUI
12. In the $EGO_TOP/gui/logs/catalina.out file, check whether the GUI
version indicates version 8.5.37:
INFO: Server version: Apache Tomcat/8.5.37
Uninstallation
Follow the instructions in this section to uninstall this update in your
cluster, if required.
1. Log on to the master host as the cluster administrator and stop the
WEBGUI service:
> egosh user logon -u Admin -x Admin
> source $EGO_TOP/cshrc.platform
> egosh service stop WEBGUI
2. On each management host, restore the backup files:
1. Remove the Tomcat folder, which was introduced by this interim
fix:
> rm -rf $EGO_TOP/gui/3.1/tomcat
2. Restore the following folders and files from your backup:
$EGO_TOP/gui/3.1/tomcat
$EGO_CONFDIR/../../gui/conf/catalina.policy
$EGO_CONFDIR/../../gui/conf/catalina.properties
$EGO_CONFDIR/../../gui/conf/server.xml
$EGO_TOP/gui/ego/3.1/platform/WEB-INF/web.xml
$EGO_TOP/gui/is/7.1/isgui/WEB-INF/web.xml
$EGO_TOP/gui/perf/3.1/perfgui/WEB-INF/web.xml
$EGO_TOP/gui/soam/7.1/soamgui/WEB-INF/web.xml
$EGO_TOP/gui/soam/7.1/symgui/WEB-INF/web.xml
3. Delete all subdirectories and files in the following directory:
> rm -rf $EGO_TOP/gui/work/*
4. On all client hosts, open your web browser and clear the browser
cache.
5. Start the WEBGUI service:
> source $EGO_TOP/cshrc.platform
> egosh service start WEBGUI
