How to fix?

Upgrade Debian:10 openldap to version 2.4.25-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openldap package and not the openldap package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

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.
