FKIE_CVE-2018-25114

Vulnerability from fkie_nvd - Published: 2025-07-23 14:15 - Updated: 2026-06-17 01:54
Severity
9.3 (Critical) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
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.

Un atacante no autenticado puede invocar install_4.php, enviar datos POST manipulados e inyectar c\u00f3digo PHP arbitrario en el archivo configure.php. Cuando la aplicaci\u00f3n incluye posteriormente este archivo, se ejecuta el payload inyectado, lo que resulta en una vulnerabilidad completa del servidor."
