Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2022-34916 impacting apache flume. Evaluated with CVSS Base Score of 9.8 (CRITICAL).

Original NVD Description

Source: NIST NVD
Apache Flume versions 1.4.0 through 1.10.0 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.
