New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

When binding against a DN during authentication, the reply from 389-ds-base will be different whether the DN exists or not. This can be used by an unauthenticated attacker to check the existence of an entry in the LDAP database.
