CVE-2026-45746

Full vulnerability record from the local CVENow database.

Description

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.3.2, the File Manager functionality in Termix contains a critical Broken Access Control vulnerability due to improper validation of the sessionId parameter. The backend trusts a client-controlled identifier without verifying that it belongs to the authenticated user. This allows an attacker to manipulate the value and access active File Manager sessions belonging to other users. Since these sessions are tied to SSH connections to remote VPS instances, exploitation allows unauthorized interaction with another user's remote filesystem. Because the File Manager exposes functionality such as file reading, writing, uploading, and execution, this vulnerability enables direct command execution on another user's VPS (RCE). Version 2.3.2 patches the issue.

      "value": "Termix es una plataforma de gestión de servidores basada en web con capacidades de terminal SSH, tunelización y edición de archivos. Antes de la versión 2.3.2, la funcionalidad de Administrador de Archivos en Termix contiene una vulnerabilidad crítica de Control de Acceso Roto debido a la validación incorrecta del parámetro sessionId. El backend confía en un identificador controlado por el cliente sin verificar que pertenezca al usuario autenticado. Esto permite a un atacante manipular el valor y acceder a sesiones activas del Administrador de Archivos pertenecientes a otros usuarios. Dado que estas sesiones están vinculadas a conexiones SSH a instancias VPS remotas, la explotación permite la interacción no autorizada con el sistema de archivos remoto de otro usuario. Debido a que el Administrador de Archivos expone funcionalidades como lectura, escritura, carga y ejecución de archivos, esta vulnerabilidad permite la ejecución directa de comandos en el VPS de otro usuario (RCE). La versión 2.3.2 corrige el problema."
