CVE-2019-14910 [CRITICAL] CWE-303 Keycloak: LDAP authentication accepts invalid passwords when using StartTLS
Keycloak: LDAP authentication accepts invalid passwords when using StartTLS
A vulnerability was found in keycloak 7.x, when keycloak is configured with LDAP user federation and StartTLS is used instead of SSL/TLS from the LDAP server (ldaps), in this case user authentication succeeds even if invalid password has entered.
A flaw was found in keycloak 7.x where an invalid password is accepted for user authentication when LDAP user federation and STARTTLS is used instead of SSL/TLS from the LDAP server. This can allow an attacker to log into a system using any entry for a password authentication and still gain access to the system.
Statement: This flaw does not affect Red Hat's Single Sign On (RHSSO) product and, thus, no patch will be forthcoming.
Mitigation: Disabling STARTTLS will fix
