Prior to version 1.11.34, there is a stored XSS vulnerability in Chamilo LMS (Verison 1.11.32) allows an attacker to inject arbitrary JavaScript into the platform’s social network and internal messaging features. When viewed by an authenticated user (including administrators), the payload executes in their browser within the LMS context. This enables full account takeover via session hijacking, unauthorized actions with the victim’s privileges, exfiltration of sensitive data, and potential self-propagation to other users. This issue has been patched in version 1.11.34."},{"lang":"es","value":"Chamilo es un sistema de gestión del aprendizaje. Antes de la versión 1.11.34, existe una vulnerabilidad XSS almacenado en Chamilo LMS (versión 1.11.32) que permite a un atacante inyectar JavaScript arbitrario en las funciones de red social y mensajería interna de la plataforma. Cuando es visto por un usuario autenticado (incluidos los administradores), la carga útil se ejecuta en su navegador dentro del contexto del LMS. Esto permite la toma de control total de la cuenta mediante el secuestro de sesión, acciones no autorizadas con los privilegios de la víctima, la exfiltración de datos sensibles y la posible autopropagación a otros usuarios.
