CVE-2023-49566Network attack vector

Authenticated JNDI injection via unfiltered DB2 parameters

Published Jul 15, 2024 · Updated Mar 27, 2025

JNDI injection in Apache Linkis DataSource before 1.6.0 allows remote authenticated users to trigger JNDI lookups through DB2 parameters. The DataSource Manager places user-controlled DB2 properties into a JDBC URL without rejecting dangerous JNDI parameters. Exploitation requires an authorized Linkis account; the advisory does not disclose the post-lookup payload or a more specific consequence.
