CVE-2025-27231

LDAP bind-password disclosure via retained host credential

Published Oct 3, 2025 · Updated Oct 3, 2025

Credential disclosure in the Zabbix Frontend allows remote authenticated users with Super Admin access to steal the saved LDAP bind password. Changing the LDAP Host leaves the stored Bind password intact, so the frontend sends that credential in a bind request to the replacement server. Exploitation requires a Super Admin account, an existing LDAP bind password, and a rogue LDAP endpoint able to receive the outbound bind.
