RSS is getting popular, as a result of which it is being linked to important financial databases. It poses a threat in two dimensions. On the server side customized feed routines can be exploited by an attacker. On the client side session hijacking and malicious code execution is possible. RSS offers great flexibility and capability to push data to the client but the security cost involved is high. Feeds are available for the end client to read; how to consume feeds is up to the end client entirely. This makes the equation difficult and less secure. This feed may be consumed by vulnerable software running in a specific zone context and the client may be vulnerable to exploits. For financial services it is important to control the consumption of the RSS feeds along with the content to make a secure RSS compartment.
