Descriptions

Grafana 2.x, 3.x, and 4.x before 4.6.4 and 5.x before 5.2.3 allows authentication bypass because an attacker can generate a valid "remember me" cookie knowing only a username of an LDAP or OAuth user.

Grafana en versiones 2.x, 3.x y 4.x anteriores a la 4.6.4 y versiones 5.x anteriores a la 5.2.3 permite la omisión de autenticación debido a que un atacante puede generar una cookie "remember me" válida conociendo solo el nombre de usuario de un usuario LDAP u OAuth.

Red Hat Gluster Storage Web Administration includes a fully automated setup based on Ansible and provides deep metrics and insights into active Gluster storage pools by using the Grafana platform. Red Hat Gluster Storage Web Administration provides a dashboard view which allows an administrator to get a view of overall gluster health in terms of hosts, volumes, bricks, and other components of GlusterFS. Issues addressed include a bypass vulnerability.
