JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to. The attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-4104. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.

Detection & IOCsextracted from sources · hover to see the quote

  • Detect JNDI lookup requests originating from JMSSink via TopicConnectionFactoryBindingName configuration — monitor for outbound LDAP/JNDI connections from Log4j 1.x JMS-configured applications
  • Flag presence of JMSSink class in deployed log4j 1.x JAR files as an indicator of attack surface exposure
  • Monitor Log4j configuration files for the presence of JMSSink appender definitions, especially those referencing external LDAP endpoints via TopicConnectionFactoryBindingName
  • Alert on deserialization activity from the JMSSink component (org/apache/log4j/net/JMSSink.class) in Log4j 1.x deployments
  • ·Vulnerability only triggers when JMSSink is explicitly configured — not exploitable in default Log4j 1.x deployments
  • ·Red Hat Satellite using log4j-over-slf4j with Candlepin is not affected because it uses the logback framework for logging
  • ·Red Hat Virtualization and OpenShift Container Platform OCP Metering stack ship vulnerable log4j but do not use JMSSink — rated Low impact
