In Apache Linkis <=1.2.0 when used with the MySQL Connector/J, a deserialization vulnerability with possible remote code execution impact exists when an attacker has write access to a database and configures a JDBC EC with a MySQL data source and malicious parameters. Therefore, the parameters in the JDBC URL should be blacklisted. Versions of Apache Linkis <= 1.2.0 are affected, we recommend users to update to 1.3.0. Mitigation: <= 1.2.0 users should upgrade to 1.3.0, or upgrade the materials of JDBC EngineConn separately, you can refer to: https://github.com/apache/incubator-linkis/tree/master/linkis-engineconn-plugins/jdbc Credit: This issue was discovered by 4ra1n and zac from ZAC Security Team References: https://lists.apache.org/thread/rxytj48q17304snonjtyt5lnlw64gccc
