Log4j vulnerability patch

On December 10th, 2021, a global and widespread critical vulnerability was discovered in Apache Log4j, an open-source Java package used to enable logging in many popular applications. This vulnerability can be exploited to enable remote code execution on servers. It affects several applications including Ephesoft Transact.

For more information about this vulnerability, please visit the Apache website.

1. Stop the Transact server service.

2. Locate any log4j-core*.jar files in the following directories and rename the JAR extension to BAK. Notate the version of the file as the same patched version of that file will need to be used in its place.

  • [Ephesoft_Directory]\Application\WEB-INF\lib
  • [Ephesoft_Directory]\Dependencies\license-util\libs\stdlibs
  • [Ephesoft_Directory]\EphesoftReports\WEB-INF\lib
  • [Ephesoft_Directory]\JavaAppServer\bin

3. For the following files that were backed up, download the following patched releases and copy the following file to its path:

    • Download log4j-core-2.8.2-p.jar then rename it to log4j-core-2.8.2.jar (remove the -p) to replace the original file.
    • Download log4j-core-2.11.2-p.jar then rename it to log4j-core-2.11.2.jar (remove the -p) to replace the original file.
    • Download log4j-core-2.12.1-p.jar then rename it to log4j-core-2.12.2.jar (remove the -p) to replace the original file

Note: If you encounter a log4j-core-*.jar release version not listed above, please contact support and submit the file for review before starting the vulnerability mitigation process.

4. Start Transact server service and verify accessibility.
