Kerentanan Improper Restriction of Communication Channel to Intended Endpoints. Skor CVSS 3.1 9.0 (Critical) menurut redhat.com.

Deskripsi (NVD)

A flaw was found in 389-ds-base. The server does not discard plaintext bytes already buffered from a client connection when negotiating StartTLS, allowing an on-path attacker to inject a crafted LDAP message that is processed after the TLS upgrade and whose response is delivered to the client in place of the client's own pending operation's response, due to messageID collision. This can cause a client application to treat a failed authentication (bind) attempt as successful.
