Artiva Agency Single Sign-On (SSO) feature vulnerability
Original Release date: 14 Apr 2014 | Last revised: 14 Apr 2014

Overview
Artiva Agency Single Sign-On (SSO) feature checks only the local Windows login name which could allow an attacker to impersonate another Artiva Agency user.

Description
Artiva Agency Single Sign-On (SSO) feature when configured with the domain name option allows the currently logged on Windows user to automatically be logged into the Artiva Agency application using the same username without any additional authentication. Artiva Agency Single Sign-On (SSO) checks only the local Window login name and as a result does not take into consideration the associated user’s domain name. By creating a local Windows user account with the same username as a Windows domain account, Artiva Agency will allow the attacker to login as the domain account to the Artiva Agency application.

Impact
An unauthenticated Artiva Agency user can create a local Windows user account with the same username as a Windows domain account and Artiva Agency will allow the attacker to login as the domain account to the Artiva Agency application.
