In particular, a device may send messages that are bigger than the max-message-size that the protocol adapter has indicated during link establishment. While the AMQP 1.0 protocol explicitly disallows a peer to send such messages, a hand crafted AMQP 1.0 client could exploit this behavior in order to send a message of unlimited size to the adapter, eventually causing the adapter to fail with an out of memory exception."},{"lang":"es","value":"En Eclipse Hono versiones 1.3.0 y 1.4.0, el adaptador de protocolo AMQP no verifica el tamaño de los mensajes AMQP recibidos desde dispositivos. En particular, un dispositivo puede enviar mensajes que son más grandes que el tamaño máximo de mensaje que el adaptador de protocolo ha indicado durante el establecimiento del enlace. Si bien el protocolo AMQP versión 1.0 explícitamente no permite a un peer enviar dichos mensajes, un cliente AMQP versión 1.0 diseñado podría explotar este comportamiento a fin de enviar un mensaje de tamaño ilimitado hacia el adaptador, lo que eventualmente causa a un adaptador un fallo con una excepción de falta de memoria"}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}],"cvssMetricV2":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"2.0","vectorString":"AV:N/AC:L/Au:N/C:N/I:N/A:P","baseScore":5.0,"accessVector":"NETWORK","accessComplexity":"LOW","authentication":"NONE","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"PARTIAL"},"baseSeverity":"MEDIUM","exploitabilityScore":10.0,"impactScore":2.9,"acInsufInfo":false,"obtainAllPrivilege":false,"obtainUserPrivilege":false,"obtainOtherPrivilege":false,"userInteractionRequired":false}]},"weaknesses":[{"source":"emo@eclipse.org","type":"Secondary","description":[{"lang":"en","value":"CWE-1284"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:eclipse:hono:1.3.0:*:*:*:*:*:*:*","matchCriteriaId":"E0069162-7F28-4FA8-9ECC-C6F884F3A33E"},{"vulnerable":true,"criteria":"cpe:2.3:a:eclipse:hono:1.4.0:*:*:*:*:*:*:*","matchCriteriaId":"A88017C9-1C6D-452D-93E5-2F762C78A586"}]}]}],"references":[{"url":"https://bugs.eclipse.org/bugs/show_bug.cgi?id=567068","source":"emo@eclipse.org","tags":["Issue Tracking","Vendor Advisory"]},{"url":"https://bugs.eclipse.org/bugs/show_bug.cgi?id=567068","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking","Vendor Advisory"]}]}}]}
