WHID 2007-28: US Embassy probes hacking of online visa appointment system
Date: 13 June 2007
Incident Type: Security Breach
WASC Threat Classification: Insufficient Authentication

If you live in a country from which you need a Visa to get to the states, you knew this would happen. The US online Visa appointment system is very open. Indeed too open. Someone in Jamaica took advantage of this to pre-allocate appointments.

While this might be classified as a business process design flaw, isn't security also about this?

Date: 01 November 2004
Incident Type: Vulnerability Disclosure
WASC Threat Classification: Insufficient Authentication, Predictable Resource Location

Following a software upgrade, Cahoot, a UK based Internet only bank allowed accessing user accounts by guessing their user names. At least on one page allowed accessing an account by only specifying the user name in the URL. The bug was open for 12 days before being discovered.

The site was taken off line for 10 hours to fix the issue. It is a significant incident, as it is one of those rare occasions where vulnerability was serious enough to force the organization to just take the site off line until it is fixed.

We somehow missed this story so it finds its way to WHID only now in late 2007.
