✅ Remediation

Before applying the update, back up your existing installation, including all applications, configuration files, databases and database settings, and so on. The References section of this erratum contains a download link (you must log in to download the update). Workaround: As per upstream: - In prior releases confirm that if the JDBC Appender is being used it is not configured to use any protocol other than Java. - Note that only the log4j-core JAR file is impacted by this vulnerability. Applications using only the log4j-api JAR file without the log4j-core JAR file are not impacted by this vulnerability. Workaround: 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. Workaround: These are the possible mitigations for this flaw for releases version 1.x: - Comment out or remove JDBCAppender in the Log4j configuration if it is used - Remove the JDBCAppender class from the server's jar files. For example: ``` zip -q -d log4j-*.jar org/apache/log4j/jdbc/JDBCAppender.class ``` Workaround: These are the mitigations available for this flaw for log4j 1.x: - Avoid using Chainsaw to view logs, and instead use some other utility, especially if there is a log view available within the product itself. - Remove the Chainsaw classes from the log4j jar files. For example: ``` zip -q -d log4j-*.jar org/apache/log4j/chainsaw/* ``` (log4j jars may be nested in zip archives within product)
