Loading vulnerability…
CVE-2017-12611 is a remote code execution vulnerability in Apache Struts affecting versions 2.0.0 through 2.3.33 and 2.5 through 2.5.10.1. The flaw arises when Freemarker tags are used with an unintentional expression instead of a string literal. In vulnerable configurations, attacker-controlled request values can be evaluated as expressions within the Struts/Freemarker rendering path, resulting in server-side expression execution and ultimately arbitrary code execution in the context of the application.

2 valid exploits after Mallory filtered fakes, detection scripts, and README-only repos (2 hidden).
This repository provides a proof-of-concept (POC) exploit for CVE-2017-12611, a remote code execution vulnerability in Apache Struts 2. The repository contains three files: a .gitattributes file, a markdown file with the OGNL payload (payload.md), and a detailed readme (read_me.md) with setup and exploitation instructions. The exploit leverages an OGNL injection payload that, when submitted to a vulnerable Struts 2 endpoint (e.g., http://<your-ip>:8080/hello.action), executes arbitrary system commands on the server. The readme guides the user to set up a vulnerable environment using Docker Compose, submit the payload via Burp Suite, and obtain a shell by transforming intercepted requests into curl commands. The exploit demonstrates RCE by running the 'id' command but can be adapted for other commands. No detection scripts or fake elements are present; the repository is a functional POC for the specified vulnerability.
This repository contains a Python script (exploit.py) and a README.md file. The script exploits the Apache Struts 2 S2-053 vulnerability (CVE-2017-12611), which allows for remote code execution via crafted OGNL expressions in HTTP GET parameters. The exploit.py script takes three arguments: a target URL, a parameter name, and a system command to execute. It constructs a malicious OGNL payload that is injected into the specified parameter and sends a GET request to the target. If successful, the output of the executed command is returned in the HTTP response. The README provides usage instructions, an example, and references to further information. The exploit is operational and allows arbitrary command execution on vulnerable Struts 2 servers.
