Descriptions

OpenStack Nova before 2012.1 allows someone with access to an EC2_ACCESS_KEY (equivalent to a username) to obtain the EC2_SECRET_KEY (equivalent to a password). Exposing the EC2_ACCESS_KEY via http or tools that allow man-in-the-middle over https could allow an attacker to easily obtain the EC2_SECRET_KEY. An attacker could also presumably brute force values for EC2_ACCESS_KEY.

OpenStack Nova versiones anteriores a 2012.1, permite a alguien con acceso a una EC2_ACCESS_KEY (equivalente a un nombre de usuario) obtener la EC2_SECRET_KEY (equivalente a una contraseña). Exponer el EC2_ACCESS_KEY por medio de http o herramientas que permiten ataques de tipo man-in-the-middle sobre https podría permitir a un atacante obtener fácilmente el EC2_SECRET_KEY. Un atacante también podría presumir valores por fuerza bruta para EC2_ACCESS_KEY.
