By setting the content-type header to application/cloudevents+json and omitting required CloudEvent attributes (id, source, type), the attacker triggers an ArgumentException in KafkaMessageConsumer.SingleMessageHandlingAsync that is treated as fatal, causing the host to stop and re-process the same poison record on every restart, resulting in a permanent crash-loop.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-755"],"vendors":[],"products":[],"references":[{"url":"https://github.com/GDATASoftwareAG/motornet/commit/b4b6979f5dd7447dd02312e27d766ae2e9d050c2","tags":[]},{"url":"https://github.com/GDATASoftwareAG/motornet/pull/1785","tags":[]},{"url":"https://github.com/GDATASoftwareAG/motornet/releases/tag/v0.19.0","tags":[]},{"url":"https://www.vulncheck.com/advisories/motor-net-kafka-denial-of-service-via-cloudevents-handler","tags":[]}],"exploitRefs":[{"url":"https://github.com/GDATASoftwareAG/motornet/commit/b4b6979f5dd7447dd02312e27d766ae2e9d050c2","tags":[]},{"url":"https://github.com/GDATASoftwareAG/motornet/pull/1785","tags":[]},{"url":"https://github.com/GDATASoftwareAG/motornet/releases/tag/v0.19.0","tags":[]}],"hasPoc":true,"ai":null}
