Information Leakage

Published: November 16, 2006

Version: 1.0

Maximum Severity Rating: Low

Background

When users are attempting to access portal functions, we strive to strike a balance between providing informative messages, but not revealing unnecessary detail to people attempting to profile the application.

Issue Summary

Two areas have been altered to fix issues where more information that was necessary was made available.

  1. When attempting to access a a page that the user does not have permission to, the user is correctly redirected to the login page. However, the page title preserves the name of the originally requested page, which has been determined to be an unnecessary information leakage.
  2. When logged in, if the user attempts to access another users profile, they are correctly redirected to a failure page. However, at that point the user can tell by the error message if the user account they tried to access is a standard user or a superuser.
