Fixed CVEs

Prerequisites

Consider the following requirements for your system:

  • Talend Jobserver 8.0.1 must be installed.

Installation

  1. Create a backup of the files in <jobserver_home>/lib , <jobserver_home>/conf and the *.bat and *.sh scripts.
  2. Stop Jobserver.
  3. Remove all files from <jobserver_home>/lib, <jobserver_home>/*.sh and <jobserver_home>/*.bat .
  4. Replace them with their patched counterparts.
  5. Recommended change of following configuration properties in <jobserver_home>/conf/TalendJobserver.properties in case you use SSL:

    # Enabled protocols for JobServer socket communication
    org.talend.remote.server.ssl.enabled.protocols=TLSv1.2,TLSv1.3
    
    # Enabled protocols for JMX management server
    org.talend.jmxmp.ssl.enabled.protocols=TLSv1.2,TLSv1.3
    
  6. Recommended to set following configuration property to false in case you want to disable the Monitoring Port 8888:

    # Enable the Monitoring port or not. true by default
    org.talend.remote.jobserver.server.TalendJobServer.ENABLE_MONITORING_PORT=true
    
  7. Add the following configuration properties to <jobserver_home>/conf/TalendJobserver.properties:

    It is recommended to set the following configuration property to true:

    # Set to true to enable authorization for all jobserver commands (recommended)
    org.talend.remote.jobserver.commons.config.JobServerConfiguration.SECURITY_MODE=true
    

    The following configuration property enables authorization for all job file deployments. This requires that on client-side ( TAC, Studio ) support for file server authorization must be available and the system property org.talend.remote.jobserver.client.old has be set to false. For more details refer to the documentation.

    # Set to true to enable authorization for all job file deployments
    ( Requires additional configuration for TAC and Studio. )
    org.talend.remote.jobserver.commons.config.JobServerConfiguration.FILESERVER_AUTHORIZATION=true
    

    The following configuration have been added to add constraints on job to prevent Denial Of Service attacks. High default have been defined, it is recommended to adapt these to your environment.

    # Maximum number of file listeners, 0 = No limit
    org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_FILE_LISTENERS=6000
    
    # Maximum number of library dependencies embedded in a job
    org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_LIBRARY_DESC_NB=1000
    # Maximum size of all library dependency names for a job
    org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_LIBRARY_DESC_SIZE=100KB
    
    # Maximum number of deployed jobs, 0 = No Limit
    org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_JOB_NB=6000
    
    # Max size that a job archive is allowed to be. The default is 1G, 0 = No limit
    org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_JOB_FILE_SIZE=1G
    
    # Maximum size of TalendJobServersFiles/archiveJobs folder, 0 = No limit, 0 = No Limit
    org.talend.remote.jobserver.commons.config.JobServerConfiguration.MAX_ARCHIVES_DIR_SIZE=100G
    

    The following configuration have been added to activate job archive signature check.

     # Activate job archive signature, 1 or more values separated by comma (',').
     # Possible values are:
     # - 'ON_DEPLOY' (legacy)
     # - 'ON_UPLOAD' (advised & default)
     org.talend.remote.jobserver.commons.config.JobServerConfiguration.JOB_ARCHIVE_SIGNATURE_CHECK=ON_UPLOAD
    
  8. An empty allow list for impersonation users is not supported anymore. If you want to allow impersonation for anyone and support jobs running without impersonation, you need to explicitly set:

    org.talend.remote.jobserver.server.TalendJobServer.RUN_AS_ALLOWLIST=anybody
    

    Please refer to the following examples to understand this setting:

RUNASALLOWLIST Run as user Execution Explanation
accepted No impersonation, OK
anybody accepted No impersonation, OK
anybody jim accepted All users allowed
* refused Must specify a user
* jim accepted All users allowed
jim,jules refused Must specify a user from the list
jim,jules jim accepted jim is in the list
ju* jules accepted jules matches ju*
  1. Check Read, Write & Execution rights on files

Per default, the rights should be:

  • rw-r--r-- (i.e. 0664) per default, meaning everybody can read, but only the owner can overwrite the file
  • rwxr-xr-x (i.e. 0655) for *.sh files, meaning everybody can read & execute, but only the owner can overwrite the file

If needed, feel free to update these rights to match your current installation environment.
Especially to allow further patch updates by a non-owner user, you might want to allow other users to have Write access.

  1. Start Jobserver

Uninstallation

  1. Stop Jobserver.
  2. Remove the files in <jobserver_home>/lib, <jobserver_home>/conf and the *.bat and *.sh scripts. and restore the unpatched counterparts from your backup.
  3. Start Jobserver

Affected files for this patch

All files in <jobserver_home>/lib, <jobserver_home>/conf and the *.bat and *.sh scripts.

Removed features

TPRUN-3775

When the option org.talend.remote.jobserver.commons.config.JobServerConfiguration.LAUNCH_SHELL_SCRIPT was set to false (which is the default value), the script files were regenerated in :

  • deployedJobPath/[jobName]/[jobName]_run.bat for Windows
  • deployedJobPath/[jobName]/[jobName]_run.sh for UNIX

These files will no longer be regenerated ( updated with valid classpath ) and thus will not be executable anymore. To see executed command please use the debug level log.

Deprecated features

TPRUN-3775

The possibility to launch from shell script using option org.talend.remote.jobserver.commons.config.JobServerConfiguration.LAUNCH_SHELL_SCRIPT set to true is deprecated and will be removed in end 2022.
