Descriptions

eLabFTW is an electronic lab notebook manager for research teams. In versions prior to 4.2.0 there is a vulnerability which allows an attacker to authenticate as an existing user, if that user was created using a single sign-on authentication option such as LDAP or SAML. It impacts instances where LDAP or SAML is used for authentication instead of the (default) local password mechanism. Users should upgrade to at least version 4.2.0.

eLabFTW es un administrador de cuadernos de laboratorio electrónicos para equipos de investigación. En versiones anteriores a 4.2.0, se presenta una vulnerabilidad que permite a un atacante autenticarse como un usuario existente, si ese usuario fue creado usando una opción de autenticación de inicio de sesión único como LDAP o SAML. Afecta a los casos en los que se usa LDAP o SAML para la autenticación en lugar del mecanismo de contraseña local (por defecto). Los usuarios deben actualizar al menos a la versión 4.2.0
