CVE-2022-42468

Apache Flume prior to 1.11.0 has an Improper Input Validation (JNDI Injection) in JMSSource

9.8 CriticalFix available

Apache Flume versions 1.4.0 through 1.10.1 are vulnerable to a remote code execution (RCE) attack when a configuration uses a JMS Source with an unsafe providerURL. This issue is fixed by limiting JNDI to allow only the use of the java protocol or no protocol.

GitHub AdvisoriesGHSA-9w4g-fp9h-3q2v 9.8

Apache Flume vulnerable to remote code execution via deserialization of unsafe providerURL

Flume’s JMSSource class can be configured with a providerUrl parameter. A JNDI lookup is performed on this name without performing validation. This could result in untrusted data being deserialized, leading to remote code execution (RCE) attack when a configuration uses a JMS Source with an unsafe providerURL. This issue is fixed in version 1.11.0.
