CVE-2025-48390

Estado: AnalizadaAlta (8.6)—

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.178, FreeScout is vulnerable to code injection due to insufficient validation of user input in the php_path parameter. The backticks characters are not removed, as well as tabulation is not removed. When checking user input, the file_exists function is also called to check for the presence of such a file (folder) in the file system. A user with the administrator role can create a translation for the language, which will create a folder in the file system. Further in tools.php, the user can specify the path to this folder as php_path, which will lead to the execution of code in backticks. This issue has been patched in version 1.8.178.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

CWE-94 (code injection) en parámetro php_path sin validación permite ejecución de código entre backticks con privilegios de administrador (PR:H). Red, requiere autenticación, acceso remoto a servicio.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

Antes de la versión 1.8.178, FreeScout era vulnerable a la inyección de código debido a una validación insuficiente de la entrada del usuario en el parámetro php_path. Las comillas invertidas no se eliminan, ni tampoco la tabulación. Al verificar la entrada del usuario, también se llama a la función file_exists para comprobar la presencia de dicho archivo (o carpeta) en el sistema de archivos. Un usuario con rol de administrador puede crear una traducción para el idioma, lo que creará una carpeta en el sistema de archivos. Además, en tools.php, el usuario puede especificar la ruta a esta carpeta como php_path, lo que provocará la ejecución de código entre comillas invertidas. Este problema se ha corregido en la versión 1.8.178."
