CVE-2019-0230 is a remote code execution vulnerability in Apache Struts affecting versions 2.0.0 through 2.5.20. The flaw is caused by forced double OGNL evaluation in situations where raw user-controlled input is evaluated within tag attributes. Under vulnerable conditions, attacker-supplied input can be interpreted as an OGNL expression more than once, enabling malicious expression injection and execution of arbitrary code within the context of the application server running the Struts application.

This repository contains a single Metasploit module: 'struts2_multi_eval_ognl.rb', which exploits double OGNL evaluation vulnerabilities in Apache Struts 2 (CVE-2019-0230 and CVE-2020-17530). The module targets web applications that use user-supplied data in tag attributes, allowing remote code execution via crafted HTTP requests. The exploit supports two main payload types: direct Unix command execution and deployment of a Meterpreter reverse shell (Linux dropper). The module is highly configurable, allowing the attacker to specify the target URI, HTTP port, parameter name, and which CVE to exploit. The attack vector is network-based, leveraging HTTP requests to inject malicious OGNL expressions. The code is weaponized, as it is part of the Metasploit framework and supports automated payload delivery and session management. No hardcoded IPs or domains are present; the attacker must supply the target's address and relevant parameters.
This repository contains a proof-of-concept (POC) exploit for CVE-2019-0230 (also known as S2-059), a remote code execution vulnerability in Apache Struts 2. The repository consists of two files: a brief README and a 'poc.txt' file containing a raw HTTP POST request. The exploit leverages OGNL injection to achieve command execution on the target server. The provided payload executes the 'ls -al' command and returns its output in the HTTP response. The exploit targets an endpoint such as '/test/test.action' on a server running a vulnerable version of Apache Struts 2. No detection scripts or framework integration are present; this is a standalone POC demonstrating the vulnerability.
