Steps for the deployment of the hotfix for Log4j 2.x vulnerabilities in QuarkXPress Server

Background: Log4Shell vulnerable jars were found, which may trigger false positives in vulnerability scanners, below hotfix will fix the same.

Solution: Below is instructions to apply the hotfix in the QuarkXPress Server (QXPS): 
 
  1. Stop QXPS Server and ensure that no instances of QXPSServerRenderer.exe are running in the task manager.
  2. Replace the old Log4j files with the new Log4J-XXX-2.17.1.jar files:
    1. Navigate to the folder “[$QXPS Installation]\dependencies” (C:\Program Files\Quark\QuarkXPress Server XXXX\dependencies)
    2. Take a backup of all the *.jar files whose name starts with “log4j-”. For example, 4 files for QXPS 2018 and QXPS 2020: log4j-1.2-api-XXX.jar, log4j-api-XXX.jar, log4j-core-XXX.jar, log4j-jcl-XXX.jar; and 2 files for QXPS 2019: log4j-api-XXX.jar, log4j-core-XXX.jar
    3. Delete all the .jar files whose name starts with “log4j-”. For example, 4 files for QXPS 2018 and QXPS 2020: log4j-1.2-api-XXX.jar, log4j-api-XXX.jar, log4j-core-XXX.jar, log4j-jcl-XXX.jar and 2 files for QXPS 2019: log4j-api-XXX.jar, log4j-core-XXX.jar
    4. Copy the following jar files from the folder “Log4j_2.17_HotFix\Log4J_2.17” in the provided hotfix to the folder “[$QXPS Installation]\dependencies” as explained in step 1.
      For all QXPS versions (QXPS 2018 to QXPS 2020):
      - log4j-api-2.17.1.jar
      - log4j-core-2.17.1.jar
      For QXPS 2018 and QXPS 2020 only:
      - log4j-1.2-api-2.17.1.jar
        log4j-jcl-2.17.1.jar
  1. Modify the file “wrapper.conf” to adhere to the new version of log4j jar files:
    1. Take a backup of the file wrapper.conf from “[$QXPS Installation]\” (C:\Program Files\Quark\QuarkXPress Server XXXX\ wrapper.conf)
    2. Edit the file wrapper.conf in “[$QXPS Installation]\” and then search and replace the following four instances of the log4j references:
      For all QXPS versions (QXPS 2018 To QXPS 2020):
      - Replace text - log4j-api-XXX.jar with log4j-api-2.17.1.jar
      - Replace text - log4j-core-XXX.jar with log4j-core-2.17.1.jar
      For QXPS 2018 and QXPS 2020 only:
      - Replace text - log4j-1.2-api-XXX.jar with log4j-1.2-api-2.17.1.jar
      - Replace text - log4j-jcl-XXX.jar with log4j-jcl-2.17.1.jar
  2. Start QXPS Server and verify that the server is creating logs in the log files in “[$QXPS Installation]\log\”.
    1. QXPS Log.log appears immediately after you have launched QXPS.
    2. QXPS Transaction Log.log appears when you send a publishing request to QXPS.
    3. QuarkXPress Server Fatal Log.log displays logs only when there is a fatal problem. For example, when you launch QXPS as an application while QXPS is already being running as a service.
