CVE-2023-49566: Apache Linkis DataSource: JDBC Datasource Module with DB2 has JNDI Injection vulnerability

[Heping Wang <peacewong () apache org>]

Severity: important

Affected versions:

- Apache Linkis DataSource * before 1.6.0

Description:

In Apache Linkis <=1.5.0, due to the lack of effective filtering
of parameters, an attacker configuring malicious 

db2

 parameters in the DataSource Manager Module will result in jndi injection. Therefore, the parameters in the DB2 URL 
should be blacklisted. 

This attack requires the attacker to obtain an authorized account from Linkis before it can be carried out.

 Versions of Apache Linkis 

<=1.5.0

 will be affected.
We recommend users upgrade the version of Linkis to version 1.6.0.
