Trustwave's SpiderLabs Security Advisory TWSL2010-007: Passlogix v-GO Self-Service Password Reset Bypass via Invalid SSL Certificate
https://www.trustwave.com/spiderlabs/advisories/TWSL2010-007.txt
Published: 2010-12-10 Version: 1.0

Analysis:

It appears that the SSL exception window is tied to the target machine.
This window itself may be a part of the application, which unfortunately happens to provide a way to browse the target machine file system for exporting certificates instead of the user's itself.

This vulnerability can be classified as 'design flaw' lacking authentication check upon accessing the file systems. The vulnerable window form is not tied to the realm of authentication domain.

Check:

The above finding can mostly be missed in normal pentest where a  pentester and the target application are the only actors.  However, Spiderlabs researchers managed to test the target application in different environment settings under their control. Thus, it is essential to consider what environmental factors may interfere with the target application logics and workflow. Draw test cases. Examine and study the application behaviors.

When the first method was tried, the Java Runtime did no

Background: Nowadays, the use of large touch screen kiosks has been prevalent.  They are to replace tradition paper-based brochures and to provide more interactive means to consumers. In restaurants, you can see a variety of food menu that can be accessible in large touch screen LCD monitor.  In your local Telcos, you can see a variety of mobile and Internet subscriptions plans.   Behind these touch screen menus are running standalone or browser-mode Adobe Flash applications which are second-to-none for interactivity and scalablity and ease of update. Data could be pulled from somewhere round their centralized web severs. Weakness: Jumping out We cannot use  iKat  at first as we do not have access to any keyboard facility. However, the trick is no-brainer. Do long press on any locations and relieve.  You should see the usual Flash context menu like: Touch "Global Settings".  A web browser window will pop up and redirect to the Adobe URL,  http://www.macromedia.c
