Descriptions

An issue was discovered in Open-Xchange OX Guard before 2.4.2-rev5. Script code can be provided as parameter to the OX Guard guest reader web application. This allows cross-site scripting attacks against arbitrary users since no prior authentication is needed. Malicious script code can be executed within a user's context. This can lead to session hijacking or triggering unwanted actions via the web interface (sending mail, deleting data etc.) in case the user has an active session on the same domain already.

Ha sido descubierto un problema en Open-Xchange OX Guard en versiones anteriores a 2.4.2-rev5. Código script puede ser usado como parámetro para la aplicación web de lectura huésped OX Guard. Esto permite ataques de XSS contra usuarios arbitrarios debido a que ninguna autenticación previa es necesaria. El código script malicioso puede ser ejecutado en un contexto de usuario. Esto puede conducir al secuestro de sesión o desencadenar acciones no deseadas a través de la interfaz web (envío de correo, eliminación de datos, etc.) en caso de que el usuario tenga una sesión activa en el mismo dominio a la vez.

Open-Xchange Guard versions 2.4.2 and below suffer from multiple cross site scripting vulnerabilities.
