Vulnerability from fkie_nvd - Published: 2018-02-09 14:29 - Updated: 2024-11-21 03:59
Severity ?
5.9 (Medium) - CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A Denial of Service vulnerability was found in Apache Qpid Broker-J 7.0.0 in functionality for authentication of connections for AMQP protocols 0-8, 0-9, 0-91 and 0-10 when PLAIN or XOAUTH2 SASL mechanism is used. The vulnerability allows unauthenticated attacker to crash the broker instance. AMQP 1.0 and HTTP connections are not affected. An authentication of incoming AMQP connections in Apache Qpid Broker-J is performed by special entities called "Authentication Providers". Each Authentication Provider can support several SASL mechanisms which are offered to the connecting clients as part of SASL negotiation process. The client chooses the most appropriate SASL mechanism for authentication. Authentication Providers of following types supports PLAIN SASL mechanism: Plain, PlainPasswordFile, SimpleLDAP, Base64MD5PasswordFile, MD5, SCRAM-SHA-256, SCRAM-SHA-1. XOAUTH2 SASL mechanism is supported by Authentication Providers of type OAuth2. If an AMQP port is configured with any of these Authentication Providers, the Broker may be vulnerable.

      "value": "Se ha encontrado una vulnerabilidad de denegaci\u00f3n de servicio (DoS) en Apache Qpid Broker-J 7.0.0, en la funcionalidad para la autenticaci\u00f3n de conexiones para los protocolos AMQP 0-8, 0-9, 0-91 y 0-10 cuando se emplean los mecanismos PLAIN o XOAUTH2 SASL. La vulnerabilidad permite que un atacante no autenticado cierre la instancia broker inesperadamente. Las conexiones AMQP 1.0 y HTTP no se han visto afectadas. La autenticaci\u00f3n de conexiones AMQP entrantes en Apache Qpid Broker-J se realiza por medio de entidades especiales llamadas \"Authentication Providers\" (proveedores de autenticaci\u00f3n). Cada Authentication Provider puede soportar varios mecanismos SASL, que se ofrecen a los clientes que se conectan como parte del proceso de negociaci\u00f3n SASL. El cliente elige el mecanismo SASL m\u00e1s adecuado para la autenticaci\u00f3n. Los Authentication Providers de los siguientes tipos soportan el mecanismo PLAIN SASL: Plain, PlainPasswordFile, SimpleLDAP, Base64MD5PasswordFile, MD5, SCRAM-SHA-256 y SCRAM-SHA-1. El mecanismo XOAUTH2 SASL est\u00e1 soportado por los Authentication Providers de tipo OAuth2. Si un puerto AMQP est\u00e1 configurado con cualquiera de estos Authentication Providers, el broker podr\u00eda ser vulnerable."
