Information Disclosure: Information Leakage

Affected Products

All Microsoft IIS web applications using ASP

Technical Description

It is possible to produce errors which may contain sensitive information about the application. By corrupting cookie values to special values like "=" the ASP engine will produce an error and send it to the clients browser.

Fix Recommendation

A possible workaound would be to configure the web server to send custom error pages when an error was produced. Of course the custom error page should not contain information about the problem itself but about the administrator the customer can inform.
