CVE-2025-10659

The Telenium Online Web Application is vulnerable due to a PHP endpoint accessible to unauthenticated network users that improperly handles user-supplied input. This vulnerability occurs due to the insecure termination of a regular expression check within the endpoint. Because the input is not correctly validated or sanitized, an unauthenticated attacker can inject arbitrary operating system commands through a crafted HTTP request, leading to remote code execution on the server in the context of the web application service account.

Summary		(es) La aplicación web Telenium Online es vulnerable debido a un endpoint PHP accesible para usuarios de red no autenticados que maneja incorrectamente la entrada proporcionada por el usuario. Esta vulnerabilidad ocurre debido a la terminación insegura de una verificación de expresión regular dentro del endpoint. Debido a que la entrada no se valida o sanea correctamente, un atacante no autenticado puede inyectar comandos arbitrarios del sistema operativo a través de una solicitud HTTP manipulada, lo que lleva a la ejecución remota de código en el servidor en el contexto de la cuenta de servicio de la aplicación web.
