Content
VULNERABILITY DETAILS:
DESCRIPTION:
The IBM Security Access Manager for Enterprise Single Sign On IMS server uses
Websphere Application Server to provide IMS server 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 IMS server
causing the server to work incorrectly. The user could also stop or uninstall
the IMS server causing a denial of service for the Access Agent clients.
Lastly the user could modify the IMS Administrator password allowing access to
the IMS Admin console and IMS information.
