Code injection in Apache Struts

Published: 5/13/2022Modified: 10/22/2025Added to CISA KEV: 3/25/2022

Description

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.
