  • Red Hat Data Grid 8.2.3

✅ Remediation

To install this update, do the following: 1. Download the Data Grid 8.2.3 server patch from the customer portal[²]. 2. Back up your existing Data Grid installation. You should back up databases, configuration files, and so on. 3. Install the Data Grid 8.2.3 server patch. Refer to the 8.2.3 Release Notes[³] for patching instructions. 4. Restart Data Grid to ensure the changes take effect. 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: For Log4j versions up to and including 2.15.0, this issue can be mitigated by removing the JndiLookup class from the classpath (example: zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class). Workaround: For Log4j 2 versions up to and including 2.16.0, this flaw can be mitigated by: - In PatternLayout in the Log4j logging configuration, replace Context Lookups like ${ctx:loginId} or $${ctx:loginId} with Thread Context Map patterns (%X, %mdc, or %MDC) like %X{loginId}. - Otherwise, in the Log4j logging configuration, remove references to Context Lookups like ${ctx:loginId} or $${ctx:loginId} where they originate from sources external to the application such as HTTP headers or user input.
