An attacker would have to construct a malicious serialized object in one of the deserialization exception record headers.\n\nThe researcher described in detail the causes of the vulnerability and the method of its exploitation. This is a perfect example of how a vulnerability can be reproduced only based on information from advisory.  \n\n\ud83d\udcdd Contents:\n\u25cf Preface\n\u25cf Concepts of Kafka\n\u25cf Preparation\n\nhttps://pyn3rd.github.io/2023/09/15/CVE-2023-34040-Spring-Kafka-Deserialization-Remote-Code-Execution/", "creation_timestamp": "2023-09-18T06:30:08.000000Z"}
