[peacewong <peacewong () apache org>]

Severity: important

Description:

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 will be 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
