Subject [jira] [Commented] (SOLR-8101) Installation script permission issues and other scripts fixes
Date Wed, 14 Oct 2015 21:39:05 GMT


Timothy Potter commented on SOLR-8101:

I've tried this out on Amazon Linux (CentOS based) and looks good. I'm hoping to commit this
soon unless there are other concerns?

>                 URL:
>             Project: Solr
>          Issue Type: Improvement
>          Components: scripts and tools
>    Affects Versions: 5.3.1
>            Reporter: Sergey Urushkin
>            Assignee: Timothy Potter
>              Labels: patch, security
>         Attachments: solr-5.3.1.patch, solr-scripts-v2.patch, solr-scripts-v3.patch
> Until [] is fixed, I suggest to improve
current shell scripts. Provided patch:
>   *  changes {{$SOLR_ENV}} default to {{/etc/default/$}} . This is
*security* issue. If {{}} is placed in directory which is writable by {{$SOLR_USER}},
solr process is able to write to it, and than it will be run by root on start/shutdown.
>   * changes permissions. {{$SOLR_USER}} should only be able to write to {{$SOLR_VAR_DIR}}.
This directory should not be readable by other users as it may contain personal information.
>   * sets {{$SOLR_USER}} home directory to {{$SOLR_VAR_DIR}} . As I can see there is no
need in {{/home/solr}} directory.
>   * adds {{-f}} option to {{}}. It should be used to safely upgrade
>   * adds quotes to unquoted variables
>   * adds leading zero to chmod commands
>   * removes group from chown commands (uses ":")
> Tested on ubuntu 14.04 amd64, but changes are pretty system-independent.
