Web 2.0 Threats and Risks for Financial Services
by Shreeraj Shah - net square - Monday, 30 April 2007.
CSRF with Web 2.0 applications

CSRF allows transactions to be carried out without an end user’s consent, making them one of the most effective attack vectors in financial applications. In Web 2.0 applications Ajax talks with backend Web services over XML-RPC, SOAP or REST. It is possible to invoke them using GET and POST methods. In other words, it is also possible to make cross-site calls to these Web services and in doing so, compromise a victim’s profile interfaced with Web services. CSRF is an interesting attack vector that takes on a new dimension in this newly defined endpoints scenario. These endpoints may be for Ajax or Web services but can also be invoked by cross-domain requests. Key financial transactions cannot depend simply on authenticated sessions, but must take extra care to process information, either by manually validating the password or by using CAPTCHA.

Conclusion

A lot more analysis needs to be done before financial applications can be integrated with their core businesses using Web 2.0. The Web security space is filling up with new attacks as we speak or offering new ways of delivering old attacks – both are dangerous where “monetary transactions” are involved. Here, we have seen just a small set of attacks. There are several other attack vectors with respect to Web 2.0 frameworks. A better threat model is required to undertake a thorough security analysis. Web 2.0 is a promising technology but also one that needs careful coding and usage practices prior to being consumed in applications.
