Hacker also disclose the Vulnerable link and Vulnerability type was Sql injection. SQL Injection is one of the many web attack mechanisms used by hackers to steal data from organizations. It is perhaps one of the most common application layer attack techniques used today.

Web application security is much more challenging than infrastructure. The top Web application vulnerabilities occur and re-occur time and again. According to survey results, only 51 percent of organizations currently have coders conduct security testing, and only 40 percent of organizations report they test during development. Vulnerabilities like these fall often outside the traditional expertise of network security managers.

To help you understand how to minimize these risks, Qualys provides this guide "Web Application Security; How to Minimize Prevalent Risk of Attacks" as a primer to web application security.
