Hackers continue to scan and exploit systems containing Log4J vulnerabilities at an unprecedented rate. On 10 December, the Spring Blog published detailed instructions for remediating Spring Boot applications using Maven or Gradle build scripts; Where this solution pattern is still accurate, the documented version is now out-of-date. Remember that even though the library may not be explicitly imported, it still might be present as a transitive dependency.
Latest Release for Log4J Vulnerabilities
The most secure version of Log4J is now version 2.17.1 (documented in our previous article). To force Spring Boot to import the most recent release of Log4J, include the following in your build scripts:
<properties> <log4j2.version>2.17.1</log4j2.version> </properties>
ext['log4j2.version'] = '2.17.1'
