CVE-2013-2251 Apache Struts 2 arbitrary OGNL code execution via crafted parameters
Last modified: 2015-07-31 06:51:52 EDT
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 188.8.131.52 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.
Upstream Advisory: http://struts.apache.org/release/2.3.x/docs/s2-016.html
Upstream bug: https://issues.apache.org/jira/browse/WW-4140

Not Vulnerable. This issue only affects struts 2, it does not affect the versions of struts as shipped with various Red Hat products.
