Abstract

If you have installed an interim fix for PM44303, Websphere Application Server 
6.1.0 Fixpack 43, 7.1.0 Fixpack 21 or Fixpack 23 which includes APAR PM44303,
there is the potential for an authenticated user to gain unauthorized access to 
resources.

Content

VULNERABILITY DETAILS:


DESCRIPTION:
The Web Administration component of Tivoli Directory Server (TDS) uses 
Websphere Application Server to provide Administrative services as a Websphere 
Enterprise Application.

If you have installed an Interim Fix for Websphere Application Server APAR 
PM44303, Websphere Application Server 6.1.0.43, Websphere Application Server 
7.1.0 Fixpack 21 or Fixpack 23 which includes APAR PM44303, you have the 
potential for an authenticated user on the network to bypass security 
restrictions, caused by an error when validating user credentials. This access 
requires a medium level of complexity. This could allow a user to gain 
unauthorized administrative access to an application and potentially gain 
access to confidential and critical customer data.

This could allow the user to modify the configuration of the TDS server causing 
the server to work incorrectly. The user could also stop or uninstall the TDS 
Admin console causing a denial of service for the TDS clients. Lastly the user 
could modify the TDS Administrator password allowing access to the TDS Admin 
console and TDS information.
