Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insecure input validation when processing serialized data in JMSSink. A remote attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests and execute arbitrary code on the target system.

Note, a non-default configuration with support for JMSSink is required to exploit this vulnerability.


Remediation

Upgrade Apache Log4j to the 2.x branch.
