Description

Apache Flume versions 1.4.0 through 1.9.0 are vulnerable to a remote code execution (RCE) attack when a configuration uses a JMS Source with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI to allow only the use of the java protocol or no protocol.

Affected products

Apache Software Foundation Apache Flume: from 1.4.0 before 1.10.0 — fixed in 1.10.0

How to fix

Upgrade to a fixed version: Apache Software Foundation Apache Flume 1.10.0. Check the vendor advisory for mitigations.
