CVE-2026-18264

NoMachine getstat Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of NoMachine. Authentication is required to exploit this vulnerability. The specific flaw exists within the web service, which listens on TCP port 4000 by default. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the service account. . Was ZDI-CAN-30634.

Summary		(es) Vulnerabilidad de inyección de comandos y ejecución remota de código NoMachine getstat. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de NoMachine. Se requiere autenticación para explotar esta vulnerabilidad. La falla específica existe dentro del servicio web, que escucha en el puerto TCP 4000 por defecto. El problema resulta de la falta de validación adecuada de una cadena proporcionada por el usuario antes de usarla para ejecutar una llamada al sistema. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de la cuenta de servicio. . Era ZDI-CAN-30634.
