In OneDev before version 4.0.3, the application's BasePage registers an AJAX event listener (`AbstractPostAjaxBehavior`) in all pages other than the login page. This listener decodes and deserializes the `data` query parameter. We can access this listener by submitting a POST request to any page. This issue may lead to `post-auth RCE` This endpoint is subject to authentication and, therefore, requires a valid user to carry on the attack. This issue was addressed in 4.0.3 by encrypting serialization payload with secrets only known to server."},{"lang":"es","value":"OneDev es una plataforma devops todo en uno. En OneDev versiones anteriores a  4.0.3, la BasePage de la aplicación registra un detector de eventos AJAX (\"AbstractPostAjaxBehavior\") en todas las páginas excepto en la página de inicio de sesión. Este oyente decodifica y deserializa el parámetro de consulta \"data\". Podemos acceder a este oyente mediante el envío de una petición  POST a cualquier página. Este problema puede conllevar a una \"post-auth RCE\".
