CVE-2014-125126 affects Simple E-Document versions 3.0 through 3.1. The application contains an unrestricted file upload flaw in its upload functionality and an authentication bypass condition tied to trust in a user-supplied cookie value. An unauthenticated attacker can send HTTP requests with a crafted cookie header, specifically access=3, to bypass normal authentication checks and reach the upload mechanism without valid credentials. The upload feature does not adequately restrict allowed file types and does not properly validate or sanitize user-controlled input, allowing upload of malicious server-executable files such as .php scripts. In environments where uploaded files are stored in a web-accessible location and executed by the server, this can be used to place a web shell and achieve remote code execution in the context of the web server process.

This repository contains a single Metasploit module (simple_e_document_upload_exec.rb) that exploits an arbitrary file upload vulnerability in Simple E-Document versions 3.0 and 3.1 (CVE-2014-125126). The exploit works by bypassing authentication (using a specific cookie) and abusing the file upload feature to upload a malicious PHP file. Once uploaded, the module executes the payload, resulting in remote code execution as the web server user. The module is weaponized, allowing the attacker to specify any PHP payload supported by Metasploit. The main endpoints targeted are the 'upload.php' script for uploading the payload and the directory where the payload is executed. The exploit is effective only if file uploads are enabled on the target system. The repository is structured as a typical Metasploit module, with all logic contained in a single Ruby file.
