WebSphere Application Server contains a flaw that may lead to unauthorized access. The issue is triggered when a context is secured using a '/*' directive. Direct access to a context's index page using its file name is covered by an authentication process, whereas a request to the directory itself is not covered. This will disclose the index page without authenticatoin, resulting in a loss of confidentiality.
