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.

In Apache Linkis <= 1.5.0, data source management module, when adding Mysql data source, exists remote code execution vulnerability for java version < 1.8.0241. The deserialization vulnerability exploited through jrmp can inject malicious files into the server and execute them.

This attack requires the attacker to obtain an authorized account from Linkis before it can be carried out.  We recommend that users upgrade the java version to >= 1.8.0241. Or users upgrade Linkis to version 1.6.0.

In Apache Linkis = 1.4.0, due to the lack of effective filtering of parameters, an attacker configuring malicious Mysql JDBC parameters in the DataSource Manager Module will trigger arbitrary file reading. Therefore, the parameters in the Mysql JDBC 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 = 1.4.0 will be affected.

We recommend users upgrade the version of Linkis to version 1.6.0.
