CVE-2013-2251, addressed by Apache Struts security bulletin S2-016, is an OGNL expression injection vulnerability in Apache Struts 2.0.0 through 2.3.15. Struts processes parameters using the action:, redirect:, and redirectAction: prefixes without sufficient filtering of attacker-controlled OGNL expressions. A remote attacker can supply a crafted prefixed parameter containing an OGNL expression and cause it to be evaluated in the server-side Struts/Java context, enabling arbitrary Java method invocation and potentially operating-system command execution.

This repository contains a single Metasploit module (struts_default_action_mapper.rb) that exploits a remote code execution vulnerability in Apache Struts 2 (CVE-2013-2251). The vulnerability arises from improper sanitization of parameters prefixed with 'action:', 'redirect:', or 'redirectAction:' in the DefaultActionMapper, allowing attackers to inject OGNL expressions via HTTP requests. The module supports both Windows and Linux targets and can deliver a variety of payloads, including Meterpreter sessions and command shells. It leverages Metasploit's HttpClient and HttpServer mixins to interact with the target and serve payloads. The module is highly weaponized, allowing for customizable payloads and automated cleanup of dropped files. Key endpoints include the default action URI and a writable directory for payload deployment. The exploit is operational over the network and requires the attacker to specify the target's action URI and, for Linux, a writable directory (default: /tmp).
