** Product Description

Authentix is a Windows-based product that offers cookie/form-based or 100%
cookie-free "Basic Authentication" website protection while keeping NT
Users Names and Passwords private. It protects all files, not just ASP
pages. It can validate against an internal database, a text file or an
external ODBC datasource. It requires Windows NT or Windows 2000 and IIS.

More information on Authentix can be found on

** Versions affected

All versions prior to version 5.3.
To check your current version number, start Authentix from the Start
Menu/Flicks Software, and look in the About box.

** Problem description

By using special characters in the URL combined with some special
circumstances it is possible to bypass the authentification mechanism of
Authentix100, thus not receiving a login-prompt. This allows arbitrary
users to view information that was not intented to be seen by them.

** Patch availability

Knowing the importance that Authentix100 plays in authentification methods,
Flicks Software has released version 5.3 of Authentix100.

All users of Authentix100 are strongly encouraged to upgrade to the latest
version of Authentix100 at
This upgrade, similar to the cost of the original product, is FREE.
