Descriptions
chain.c in back-ldap in OpenLDAP 2.4.x before 2.4.24, when a master-slave configuration with a chain overlay and ppolicy_forward_updates (aka authentication-failure forwarding) is used, allows remote authenticated users to bypass external-program authentication by sending an invalid password to a slave server.
chain.c en back-ldap en OpenLDAP v2.4.x anteriores a v2.4.24 cuando se utiliza una configuración maestro-esclavo con una superposición de la cadena y policy_forward_updates (también conocido como authentication-failure forwarding), permite a usuarios remotos autenticados eludir la autenticación por programa externo mediante el envío de una contraseña no válida para un servidor esclavo.
Multiple vulnerabilities were found in OpenLDAP, allowing for Denial of Service or a man-in-the-middle attack. Versions less than 2.4.35 are affected.
