PK17838 also occurs on the v5.0 release yet a fix was only      
made for v5.1 and v6.0. We need to backport the fix to the      
v5.0 release as well.

PROBLEM SUMMARY

USERS AFFECTED:
Users of the administrative console application of Websphere Application
Server version 5.0.2.

PROBLEM DESCRIPTION:
This is a security vulnerability issue where malicious users can give
html scripts as input to some administrative console pages and
thereby access sensitive information.

RECOMMENDATION:
None

This issue is caused because HTML characters are not escaped
when data is output by the GUI.

PROBLEM CONCLUSION:                                             
As part of the code fix HTML input is encoded and sanitized so  
that the value is not interpreted but treated as normal input.  
                                                                
There will be no more service packs for version 5.0.2. The fix  
for this APAR will be available via iFix.

The Update Installer can be downloaded from the following link:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg21205991

The Update Installer for V5.0 does not have a maintenance directory.
It uses fixpacks and fixes as the location of the unpacked files.

1) Copy PKxxxxx.jar file directly to the maintenance directory

2) Shutdown WebSphere
Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere 
instance that maintenance is being applied to.

3) Launch Update Installer

4) Enter the installation location of the WebSphere product you want to update.

5) Select the "Install maintenance package" operation.

6) Enter the file name of the maintenance package to install (PKxxxxx.jar file which was copied 
in the maintenance directory). The V5.0 and V5.1 fix packs and fixes are unpacked as .jar files 
and should be unpacked into fixpacks or fixes directory.
