Security advisory: Authentix100

Release Date: 1 november 2000

Vendor: Flicks Software (http://www.flicks.com)



** 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

http://www.flicks.com/authentix100

This upgrade, similar to the cost of the original product, is FREE.
