CVE-2022-34916Network attack vector

Remote code execution via unrestricted JNDI lookup

Published Aug 21, 2022 · Updated Aug 3, 2024

Remote code execution in Apache Flume 1.4.0 through 1.10.0 allows remote attackers to execute code through a JMS Source JNDI LDAP URI. JMSMessageConsumer passes destinationName directly to InitialContext.lookup without restricting its URI scheme, allowing an LDAP lookup to attacker-controlled infrastructure. Exploitation requires a JMS Source configured with the malicious LDAP destination and attacker control of that LDAP server; successful execution runs in the Flume agent's context.
