CVE-2023-46801Network attack vector

Authenticated code execution via JRMP deserialization

Published Jul 15, 2024 · Updated Sep 13, 2024

Deserialization in Apache Linkis DataSource 1.4.0 through 1.5.0 allows remote authenticated users to execute code via JRMP. The MySQL data-source creation path deserializes attacker-controlled JRMP content, permitting malicious files to be written and run on the server. Exploitation requires an authorized Linkis account and a server running Java before 1.8.0_241, and results in server-side code execution.
