Sergey Urushkin updated SOLR-8101:
----------------------------------
Attachment: (was: solr-5.3.1.patch)
> Installation script permission issues and other scripts fixes
> -------------------------------------------------------------
>
> Key: SOLR-8101
> URL: https://issues.apache.org/jira/browse/SOLR-8101
> Project: Solr
> Issue Type: Improvement
> Components: scripts and tools
> Affects Versions: 5.3.1
> Reporter: Sergey Urushkin
> Labels: patch, security
> Attachments: solr-5.3.1.patch
>
>
> Until [https://issues.apache.org/jira/browse/SOLR-7871] is fixed, I suggest
> to improve current shell scripts. Provided patch:
> * changes {{$SOLR_ENV}} default to {{/etc/default/solr.in.sh}} . This is
> *security* issue. If {{solr.in.sh}} is placed in directory which is writable
> by {{$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}} {{$SOLR_INSTALL_DIR/server/solr-webapp}}
> {{$SOLR_INSTALL_DIR/server/logs}} . {{solr-webapp}} directory might be
> inspected more. These directories should not be readable by other users as
> they 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 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.
