Weakness: CWE-502

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.

Affected products

Apache Software Foundation Apache Linkis: from 1.4.0 before 1.6.0 — fixed in 1.6.0

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Linkis 1.6.0. Check the vendor advisory for mitigations.
