CVE-2022-39312Public exploitNetwork attack vector

Remote command execution via unfiltered JDBC parameters

Published Oct 25, 2022 · Updated Apr 22, 2025

Deserialization in DataEase before 1.15.2 allows remote attackers to execute system commands through crafted MySQL JDBC parameters. MysqlConfiguration.getJdbc() appends extraParams directly to the connection URL without rejecting deserialization-enabling options. Exploitation requires DataEase to connect to an attacker-controlled MySQL server; successful commands run with server privileges.
