Overview
org.springframework:spring-webmvc is a package that provides Model-View-Controller (MVC) architecture and ready components that can be used to develop flexible and loosely coupled web applications.
Affected versions of this package are vulnerable to Multipart Content Pollution. It provides client-side support for multipart requests. When the server application (server A) receives input from a remote client, and then uses that input to make a multipart request to another server (server B), it can be exposed to an attack, where an extra multipart is inserted in the content of the request from server A, causing server B to use the wrong value for a part it expects. This could to lead privilege escalation, for example, if the part content represents a username or user roles.
