Fuzzing Risks for Rich HTML Applications

Fuzzing Risks for Rich HTML Applications

A recent research project showed that it was possible to shift money from bank accounts to multiple others in other banks by simply tampering the form scanner parameters on one account. The exploitation demonstrated the vulnerability of online banking sites when rich html applications are used to enhance the customer experience and insuffi cient care is taken to harden the site. The attack is commonly known as a cross-site scripting (XSS) attack and relies on session hijacking between the client side technologies and the server side services. The break is exploited in various ways to change the instructions and to circumvent a number of security features including one-time passwords (OTP).
