CVE-2022-25167Network attack vector

Remote code execution via unchecked JNDI lookup

Published Jun 14, 2022 · Updated Aug 3, 2024

Deserialization in Apache Flume 1.4.0 through 1.9.0 allows remote attackers to execute code through a JMSSource JNDI LDAP URI. JMSSource passes its configured connectionFactory name to a JNDI lookup without validating the URI scheme, allowing an LDAP response to supply untrusted serialized data. Exploitation requires a JMS Source configured with the LDAP URI and attacker control of the referenced LDAP server.
