If you have installed an interim fix for PM44303, Websphere Application Server Fixpack 21 or Fixpack 23 which includes APAR PM44303, there is the potential for an authenticated user to gain access to unauthorized resources.
The Web Portal Manager component of Tivoli Access Manager for e-business (TAMeb) 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 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 TAMeb server causing the server to work incorrectly. The user could also stop or uninstall the TAMeb Admin console causing a denial of service for the TAMeb clients. Lastly the user could modify the TAMeb Administrator password allowing access to the TAMeb Admin console and TAMeb information.
