CVE-2026-45743

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. 16 file-manager endpoints in Termix prior to version 2.3.2 do not verify that the requesting user owns the SSH session identified by `sessionId`. An authenticated attacker who knows or guesses another user's active `sessionId` can read, write, delete, download, and execute files on the victim's connected SSH host. Version 2.3.2 patches the issue.

Summary		(es) Termix es una plataforma de gestión de servidores basada en web con capacidades de terminal SSH, tunelización y edición de archivos. 16 puntos finales del gestor de archivos en Termix anteriores a la versión 2.3.2 no verifican que el usuario solicitante sea el propietario de la sesión SSH identificada por ’sessionId’. Un atacante autenticado que conoce o adivina la ’sessionId’ activa de otro usuario puede leer, escribir, eliminar, descargar y ejecutar archivos en el host SSH conectado de la víctima. La versión 2.3.2 corrige el problema.
