RDS Tivoli: http://www-01.ibm.com/support/docview.wss?uid=swg24032905
RDS Apache: End August 2012

Workarounds:
In the meantime, this risk can be mitigated by following the below steps.

1. Download the rds-help.zip file and extract the rds-help.war

1. FTP: ftp://public.dhe.ibm.com/software/rational/Directory_server/rds-help.zip

2. HTTP: http://public.dhe.ibm.com/software/rational/Directory_server/rds-help.zip

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

4. Delete/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:
<RDS/RDA install location>/WebAccessServer/Start_RDAWebServer.sh

The latest rds-help.war file is now installed which does not have the security vulnerabilities.

Note: This help file has contents for RDS versions 5.2(Tivoli) and later, and RDS 5.1.1 (Apache) and later.
