CVE-2024-42362Public exploitNetwork attack vector

Authenticated code execution via unsafe YAML deserialization

Published Aug 20, 2024 · Updated Aug 21, 2024

Unsafe deserialization in Apache HertzBeat before 1.6.0 allows remote authenticated users to execute arbitrary code through monitor imports. YamlImExportServiceImpl.parseImport passes the uploaded YAML stream to SnakeYAML Yaml.load, which instantiates attacker-selected Java objects. Access requires an admin or user role; a crafted import can load a remote malicious JAR and execute commands in the server process.
