Descriptions

SOGo 2.x before 2.4.1 and 3.x through 5.x before 5.1.1 does not validate the signatures of any SAML assertions it receives. Any actor with network access to the deployment could impersonate users when SAML is the authentication method. (Only versions after 2.0.5a are affected.)

SOGo versiones 2.x anteriores a 2.4.1 y versiones 3.x hasta 5.x anteriores a 5.1.1, no comprueba las firmas de las aserciones SAML que recibe. Cualquier actor con acceso a la red del despliegue podría suplantar a usuarios cuando SAML es el método de autenticación. (Sólo las versiones posteriores a 2.0.5a están afectadas)
