FKIE_CVE-2025-9494

Vulnerability from fkie_nvd - Published: 2025-09-23 02:15 - Updated: 2026-10-11 20:10
Severity
8.5 (High) - CVSS:4.0/AV:A/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
An OS command injection vulnerability has been discovered in the Vitogate 300, which can be exploited by malicious users to compromise affected installations. Specifically, the `/cgi-bin/vitogate.cgi` endpoint is affected, when the `form` JSON parameter is set to `form-0-2`. The vulnerability stems from the fact that that function at offset 0x21c24 does not properly sanitize supplied input before interpolating it into a format string which gets passed to `popen()`. Consequently, an authenticated attacker is able to inject arbitrary OS commands and thus gain code execution on affected devices.

Espec\u00edficamente, el endpoint \u0027/cgi-bin/vitogate.cgi\u0027 se ve afectado cuando el par\u00e1metro JSON \u0027form\u0027 se establece en \u0027form-0-2\u0027. La vulnerabilidad se deriva del hecho de que esa funci\u00f3n en el offset 0x21c24 no sanitiza adecuadamente la entrada proporcionada antes de interpolarla en una cadena de formato que se pasa a \u0027popen()\u0027. En consecuencia, un atacante autenticado es capaz de inyectar comandos del sistema operativo (OS) arbitrarios y as\u00ed obtener ejecuci\u00f3n de c\u00f3digo en los dispositivos afectados."
