Descriptions

lib/moodlelib.php in Moodle through 2.6.11, 2.7.x before 2.7.10, 2.8.x before 2.8.8, and 2.9.x before 2.9.2 relies on the PHP mt_rand function to implement the random_string and complex_random_string functions, which makes it easier for remote attackers to predict password-recovery tokens via a brute-force approach.

lib/moodlelib.php en Moodle hasta la versión 2.6.11, 2.7.x en versiones anteriores a 2.7.10, 2.8.x en versiones anteriores a 2.8.8 y 2.9.x en versiones anteriores a 2.9.2 se basa en la función PHP mt_rand para la implementación de las funciones random_string y complex_random_string, lo que hace que sea más fácil para atacantes remotos predecir tokens de recuperación de contraseña a través de una aproximación por fuerza bruta.
