Descriptions

The MNET authentication functionality in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 allows remote authenticated users to impersonate other user accounts by using the Login As feature in conjunction with a remote MNET single sign-on capability, as demonstrated by a Mahara site.

La funcionalidad de autenticación MNET en Moodle v1.9.x antes de v1.9.15, v2.0.x antes de v2.0.6 y v2.1.x antes de v2.1.3 permite hacerse pasar por otras cuentas de usuario a usuarios remotos autenticados mediante el uso de la funcionalidad "Login As" junto con una funcionalidad remota de inicio de sesión único (Single-Sign-On), tal y como lo demuestra un sitio hecho con Mahara.

Several security issues have been fixed in Moodle, a course management system for online learning.
