What to Know

Asymmetric Resource Consumption vulnerability in Apache Directory LDAP API.

Storing a password using the bcrypt algorithm with a high force like 30 in a LDAP server that supports this algorithm will cause the server CPU to run for hours checking the credentials. A bounded cost should be enforced to avoid a server DOS.

This issue affects Apache Directory LDAP API: from 2.1.0 before 2.1.9.

Users are recommended to upgrade to version 2.1.9, which fixes the issue. (NVD)
