CVE-2022-23302: Deserialization of untrusted data in JMSSink in Apache Log4j 1.x

Published Jan 18, 2022
·
Updated

A flaw was found in the Java logging library Apache Log4j in version 1.x. JMSSink in Log4j 1.x is vulnerable to deserialization of untrusted data. This allows a remote attacker to execute code on the server if JMSSink is deployed and has been configured to perform JNDI requests.

Other sources

Apache Log4j could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an unsafe deserialization in JMSSink. By sending specially-crafted JNDI requests using TopicConnectionFactoryBindingName configuration, an attacker could exploit this vulnerability to execute arbitrary code on the system.

— IBM

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.

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.

Information

These are the possible mitigations for this flaw for releases version 1.x: - Comment out or remove JMSSink in the Log4j configuration if it is used - Remove the JMSSink class from the server's jar files. For example: ``` zip -q -d log4j-*.jar org/apache/log4j/net/JMSSink.class ``` - Restrict access for the OS user on the platform running the application to prevent modifying the Log4j configuration by the attacker.
