Description Adam Mariš 2017-06-01 03:05:14 EDT

Applications that do not change the value of the MvcViewFactoryCreator useSpringBinding property which is disabled by default (i.e. set to “false”) can be vulnerable to malicious EL expressions in view states that process form submissions but do not have a sub-element to declare explicit data binding property mappings.
