AI-analyzed exploit summary This exploit targets osCommerce 2.3.4.1 by injecting PHP code into the configuration file via an unauthenticated reinstallation process. It leverages the lack of authentication checks in the install.php script to execute arbitrary commands.

A remote code execution vulnerability exists within osCommerce Online Merchant version 2.3.4.1 due to insecure default configuration and missing authentication in the installer workflow. By default, the /install/ directory remains accessible after installation. An unauthenticated attacker can invoke install_4.php, submit crafted POST data, and inject arbitrary PHP code into the configure.php file. When the application later includes this file, the injected payload is executed, resulting in full server-side compromise.
