Technical Analysis

Authentication bypass on medical software in general is a big utility to both an attacker and a liability for medical professionals using the software.

Where is may be less applicable in utility is simply in where it is used. The list of labs that do use this software is listed straight on the software’s website which hopefully allowed them to communicate the importance of patching before this vulnerability was announced (and hopefully they applied additional compensating controls in the process): http://blis.cc.gatech.edu/index.php
