Descriptions
OpenStack Keystone Folsom, Grizzly before 2013.1.3, and Havana, when using LDAP with Anonymous binding, allows remote attackers to bypass authentication via an empty password.
OpenStack Swift Folsom, Grizzly anterior a 2013.1.3 y Havana, cuando utilizan LDAP con binding anónimo, permite a atacantes remotos evitar la autenticación con una contraseña en blanco.
Eoghan Glynn and Alex Meade discovered that Keystone did not properly perform expiry checks for the PKI tokens used in Keystone. If Keystone were setup to use PKI tokens, a previously authenticated user could continue to use a PKI token for longer than intended. This issue only affected Ubuntu 12.10 which does not use PKI tokens by default. Jose Castro Leon discovered that Keystone did not properly authenticate users when using the LDAP backend. An attacker could obtain valid tokens and impersonate other users by supplying an empty password. By default, Ubuntu does not use the LDAP backend. Various other issues were also addressed.
