  2. Stop the WebAccessServer (apache tomcat server)
    • Windows:
      <RDS\RDA install location>\WebAccessServer\apache-tomcat-x.0.xx\bin\catalina.bat stop
    • UNIX / Linux:
      <RDS/RDA install location>/WebAccessServer/apache-tomcat-x.0.xx/bin\catalina.sh stop

  3. Go to the location where the war file is located in the RDS/RDA install location.
    • Windows:
      <RDS\RDA install location>\WebAccessServer\apache-tomcat-x.0.xx\webapps\
    • UNIX / Linux:
      <RDS/RDA install location>/WebAccessServer/apache-tomcat-x.0.xx/webapps/

  4. Delete (or backup) the following:
    file: rds-help.war
    directory: rds-help

  5. Replace the rds-help.war downloaded.

  6. Start the WebAccessServer
    • Windows:
      <RDS\RDA install location>\WebAccessServer\Start_RDAWebServer.bat
    • UNIX / Linux:
      <RDS/RDA install location>/WebAccessServer/Start_RDAWebServer.sh
The latest rds-help.war file is now installed which does not have the security vulnerabilitys.
