Preparation

Report & Form
^^^^^^^^^^^^^

In PHP 5.x the QFQ extension needs  the PHP MySQL native driver. The following functions are used and are only available with the
native driver (see also: http://dev.mysql.com/downloads/connector/php-mysqlnd/):

* mysqli::get_result (important),
* mysqli::fetch_all (nice to use)

To normalize UTF8 input, the *php5-intl* resp. *php7.0-intl* package is needed by

* normalizer::normalize()

59
For the `download`_ function, the programs `pdftk` and `file` are necessary to concatenate PDF files.
60

61
62
Preparation for Ubuntu 14.04::

63
64
	sudo apt-get install php5-mysqlnd php5-intl
	sudo apt-get install pdftk file                # for file upload and PDF
65
66
67
	sudo php5enmod mysqlnd
	sudo service apache2 restart

Preparation for Ubuntu 16.04::
69

70
	sudo apt install php7.0-intl
71
	sudo apt install pdftk libxrender1 file        # for file upload, PDF and 'HTML to PDF' (wkhtmltopdf)
72

73
.. _wkhtml:
74

75
76
wkhtmltopdf
^^^^^^^^^^^
77

78
79
`wkhtmltopdf <http://wkhtmltopdf.org/>`_ will be used by QFQ to offer 'website print' and 'HTML to PDF' conversion.
The program is not included in QFQ and has to be manually installed.
80

81
82
83
84
* The Ubuntu package `wkhtmltopdf` needs a running Xserver - this does not work on a headless webserver.

  * Best is to install the QT version from the named website above.
  * In case of trouble with wkhtmltopdf, also install 'libxrender1'.
85

86
In `config-qfq-ini`_ specify the:
87

88
89
90
91
92
93
94
95
* installed `wkhtmltopdf` binary:

  * `WKHTMLTOPDF = /.../wkhtmltopdf`

* the site base URL:

  * `BASE_URL_PRINT = http://example.com/`

96

97
98
**Important**: To access FE_GROUP protected pages or content, it's necessary to disable the `[FE][lockIP]` check! `wkhtml`
will access the Typo3 page locally (localhost) and that IP address is different from the client (=user) IP.
99
100

Configure via Typo3 Installtool `All configuration > $TYPO3_CONF_VARS['FE']`: ::
101
102
103

   [FE][lockIP] = 0

104
105
106
107
108
**Warning**: this disables an important anti-'session hijacking' protection. The security level of the whole installation
will be *lowered*! Again, this is only needed if `wkhtml` needs access to FE_GROUP protected pages & content. As an
alternative to lower the security level, create a separated page subtree which is only accessible (configured via
Typosript) from specific IPs **or** if a FE-User is logged in.

109
110
If there are problems with converting/downloading FE_GROUP protected pages, check `SHOW_DEBUG_INFO = download` to debug.

HTML to PDF conversion
''''''''''''''''''''''

`wkhtmltopdf` converts a website (local or remote) to a (multi)-page PDF file. It's mainly used in `download`_.

Print
'''''

Different browser prints the same page in different variations. To prevent this, QFQ implements a small PHP wrapper

120
`print.php` with uses `wkhtmltopdf` to convert HTML to PDF.

122
123
124
125
126
127
128
129
130
131
Provide a `print this page`-link (replace {current pageId})::

	<a href="typo3conf/ext/qfq/qfq/api/print.php?id={current pageId}">Print this page</a>

Any parameter specified after `print.php` will be delivered to `wkhtmltopdf` as part of the URL.

Typoscript code to implement a print link on every page::

	10 = TEXT
	10 {
132
		wrap = <a href="typo3conf/ext/qfq/qfq/api/print.php?id=|&type=2"><span class="glyphicon glyphicon-print" aria-hidden="true"></span> Printview</a>

		data = page:uid
	}

Setup
-----

* Install the extension via the Extensionmanager.

  * If you install the extension by manual download/upload and get an error message
    "can't activate extension": rename the downloaded zip file to `qfq.zip` or `qfq_<version>.zip` (e.g. version: 0.9.1).

  * If the Extensionmanager stops after importing: check your memory limit in php.ini.

* Enable the online local-documentation_.
* Copy/rename the file *<Documentroot>/typo3conf/ext/<ext_dir>/config.example.qfq.ini* to
  *<Documentroot>/typo3conf/config.qfq.ini* and configure the necessary values: `config.qfq.ini`_
  The configuration file is outside the extension directory to not loose it during updates.

* When the QFQ Extension is called the first time on the Typo3 Frontend, the file *<ext_dir>/qfq/sql/formEditor.sql* will
151
  played and fills the database with the *Form editor* records. This also happens automatically after each software update of QFQ.

It's also possible to setup custom variables in `config.qfq.ini`.

E.g. to setup a contact address and reuse the information inside your installation do:

 * `config.qfq.in`::

		ADMINISTRATIVE_CONTACT = john@doe.com
		ADMINISTRATIVE_ADDRESS = John Doe, Hollywood Blvd. 1, L.A.
		ADMINISTRATIVE_NAME = John Doe

 * Somewhere in a `Form` or in `Report`::

      {{ADMINISTRATIVE_CONTACT:Y}}, {{ADMINISTRATIVE_ADDRESS:Y}}, {{ADMINISTRATIVE_NAME}}

.. _`VariablesAddBySql`:

Variables add by SQL
^^^^^^^^^^^^^^^^^^^^

A specified SELECT statement in `config.qfq.ini`_ in variable `VAR_ADD_BY_SQL` fill be fired after filling the SYSTEM STORE.
The query should have 0 (nothing happens) or 1 row. The column names and column values will be added as variables to the SYSTEM_STORE.
Existing variables will be overwritten. Be carefull not to overwrite needed values.
 
This option is usefull to make generic custom values, saved in the database, accessible to all QFQ Report and Forms.
Access such variables as usual via `{{<varname>:Y}}`.

489
.. _`periodId`:
490
491
492
493
494
495
496

periodId
''''''''

This is

* a usecase, implemented via `VariablesAddBySql`_,
497
* a way to access `Period.id` with respect to the current period (the period itself is custom defined).
498
499
500
501
502

After a full QFQ installation, three things are prepared:

* a table `Period` (extend / change it to your needs, fill them with your periods),
* one sample record in table `Period`,
503
* in `config.qfq.ini`_ the default definition of `VAR_ADD_BY_SQL` will set the variable `periodId` during QFQ load.
504
505
506
507
508

511

Websites, delivering semester data, schoolyears schedules, or any other type or periods, often need an index to the
*current* period. One way is a) to mark the current period and b) to change the marker every time when the next period
becomes current.
The QFQ approach works without a marker and without manual intervention: the whished index will be computed during QFQ load.

In `config.qfq.ini`: ::

512
	VAR_ADD_BY_SQL = 'SELECT id AS periodId FROM Period WHERE start<=NOW() ORDER BY start DESC LIMIT 1'
513
514
515
516
517
518
519
520
521
522
523
524
525

a variable 'periodId' will automatically computed and filled in STORE SYSTEM. Access it via `{{periodId:Y0}}`.
To get the name and current period: ::

  SELECT name, ' / ', start FROM Period WHERE id={{periodId:Y0}}

Typically, it's necessary to offer a 'previous' / 'next' link. In this example, the STORE SIP holds the new periodId: ::

  SELECT CONCAT('id={{pageId:T}}&periodId=', {{periodId:SY0}}-1, '|Next') AS _Page, ' ', name, ' ', CONCAT('id={{pageId:T}}&periodId=', {{periodId:SY0}}+1, '|Next') AS _Page FROM Period AS s WHERE s.id={{periodId:SY0}}

Take care for minimum and maximum indexes (do not render the links if out of range).

DB USER privileges
^^^^^^^^^^^^^^^^^^

The specified DB User needs privileges to the database of at least: SELECT / INSERT / UPDATE / DELETE / SHOW.

To apply automatically QFQ-'DB UPDATE' the following rights are mandatory too: CREATE / ALTER

To get access to the Typo3 installation, 'dbuser' should also have acces to the Typo3 Database with at least SELECT / INSERT / UPDATE / DELETE.

.. _`ExceptionMaxLength`:

Exception for SECURITY_GET_MAX_LENGTH
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If it is necessary to use a GET variable which exceeds SECURITY_GET_MAX_LENGTH limit, name the variable with '_<num>' at
544
the end. E.g. `my_long_variable_130`. Such a variable has an allowed length of 130 chars. Access the variable as
545
546
547
usual with the variable name: `{{my_long_variable_130:C:...}}`.

555
556
If you get a 'Page forbidden / not found' there might be some Webserver restrictions. E.g. the Typo3 example of `.htaccess`
in the Typo3 installation folder will forbid access to any extension documentation (which is a good idea on a productive
557
558
server). For a development server instead, deactivate the forbid rule of 'documentation'. In `.htaccess` (snippet from
Typo3 7.6 _.htaccess): ::
559

560
561
  production:   RewriteRule (?:typo3conf/ext|typo3/sysext|typo3/ext)/[^/]+/(?:Configuration|Resources/Private|Tests?|Documentation|docs?)/ - [F]

571
572
SIPs
----

The following is a technical background information. Not needed to just use QFQ.

573
The SIPs (=Server Id Pairs) are uniq timestamps, created/registered on the fly for a specific browser session (=user). Every SIP is
574
575
576
577
578
579
580
581
582
583
584
585
586
587
registered on the server (= stored in a PHP Session) and contains one or more key/value pairs. The key/value pairs never leave
the server. The SIPs will be used:

* to protect values not to be spoofed by anyone,
* to protect values not to be altered by anyone,
* to grant access, e.g.:

  * load and save forms,
  * upload files,
  * download files,
  * PHP AJAX pages.

SIPs becomes invalid, as soon as the current browser session is destroyed. The client (= user) can't manipulate the content
of SIPs - it's only possible to reuse already registered SIPs by the user, who already owns the session.
588
589
590
591
592

Access privileges
-----------------

The Typo3 FE Groups can be used to implement access privileges. Such groups are assigned to
593

594
595
596
597
598
599
600
* Typo3 FE users,
* Typo3 pages,
* and/or Typo3 content records (e.g. QFQ records).

This will be used for general page structure privileges.

A `record base` privileges controlling (e.g. which user can edit
601
602
which person record) will be implicit configured, by the way that records are viewable / editable (or not) through
SQL in the specific QFQ tt-content statements.

Typo3 QFQ content element
-------------------------

Insert one or more QFQ content elements on a Typo3 page. Specify column and language per content record as wished.

The title of the QFQ content element will not be rendered. It's only visible in the backend for orientation.

Databases
---------

A Typo3 / QFQ Installation needs at least two databases. One for the Typo3 installation and one for QFQ.

QFQ itself can be separated in 'QFQ system' and 'QFQ data' databases, if necessary (than at least three databases are needed).
Furthermore a `Form` can operate on any additional database, specified per `Form`.parameter.dbIndex and configured via `config.qfq.ini`_.

* Option 'A' is the most simple and commonly used.
* Option 'B' separate the T3 and QFQ databases on two database hosts.
* Option 'C' is like 'B' but with a shared 'QFQ data'-database between three 'Typo3 / QFQ' instances.
* Further variants are possible.

+---+----------------+--------------+-------------------------------+------------------------------+----------------------------------+
|   | Domain         | Website Host | T3                            | QFQ system                   | QFQ data                         |
+===+================+==============+===============================+==============================+==================================+
| A | standalone.edu | 'w'          | <dbHost>, <dbname>_t3, <dbnameSingle>_db                                                        |

+---+----------------+--------------+-------------------------------+------------------------------+----------------------------------+
| C | appC1.edu      | 'wAppC'      | <dbHostAppC>, <dbnameC1>_t3   | <dbHostC>, <dbnameSysC1>_db  | <dbHostData>_db, <dbNameData>_db |
+---+----------------+--------------+-------------------------------+------------------------------+----------------------------------+

+---+----------------+--------------+-------------------------------+------------------------------+----------------------------------+
| C | appC3.edu      | 'wAppC3'     | <dbHostAppC3>, <dbnameC3>_t3  | <dbHostC3>, <dbnameSysC3>_db | <dbHostData>_db, <dbNameData>_db |
+---+----------------+--------------+-------------------------------+------------------------------+----------------------------------+

In `config.qfq.ini`_ mutliple database credentials can be prepared. Mandatory is at least one credential setup like
`DB_1_USER`, `DB_1_SERVER`, `DB_1_PASSWORD`, `DB_1_NAME`. The number '1' indicates the `dbIndex`. Increment the number
to specify further database credential setups.

Often the `DB_1_xxx` is identically to the used Typo3 database credentials.

If not explicit specified, 'QFQ system' and 'QFQ database' will use the same database with the same credentials (setup 'A').

To define separate 'QFQ data' and 'QFQ system', in `config.qfq.ini`_ define  `DB_1_USER`, ... (e.g. 'QFQ data') and `DB_2_USER`,
... (e.g. 'QFQ system') and specify the assignment::

	DB_INDEX_DATA = 1
	DB_INDEX_QFQ = 2

To let a form operate (show, load and save) on a different database, use `Form.parameter.dbIndexData` (see `form-parameter`_).

Different QFQ versions, shared database
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When using different QFQ versions and a shared 'QFQ data'-database, there is some risk of conflicting
'QFQ system' tables. Best is to always use the same QFQ version on all instances.

Variable
========
782

783
784
Most elements of a Form, FormElement or Report might contain (QFQ) variables. Such variables are surrounded by
double curly braces. Three different types of functionality are provided. Access to:
785

786
787
788
* `store-variables`_
* `sql-variables`_
* `column-variables`_
789

790
Some examples, including nesting::
791

792
793
794
795
796
  # Store
  #---------------------------------------------
  {{r}}
  {{index:FS}}
  {{name:FS:alnumx:s}}
797

798
799
800
  # SQL
  #---------------------------------------------
  {{SELECT name FROM person WHERE id=1234}}
801

802
803
804
805
  # Columns
  #---------------------------------------------
  {{10.pId}}
  {{10.20.pId}}
806

807
808
809
810
811
  # Nesting
  #---------------------------------------------
  {{SELECT name FROM person WHERE id={{r}} }}
  {{SELECT name FROM person WHERE id={{key1:C:alnumx}} }} # explained below
  {{SELECT name FROM person WHERE id={{SELECT id FROM pf LIMIT 1}} }} # it's more efficient to use only one query
812
813


814
Leading and trailing spaces inside curly braces are removed.
815

816
817
  * *{{ SELECT "Hello World"   }}* becomes *{{SELECT "Hello World"}}*
  * *{{ varname   }}* becomes *{{varname}}*

Types

821

822
.. _`store-variables`:
823

824
825
Store variables
^^^^^^^^^^^^^^^
826

827
Syntax:  *{{VarName[:<store / prio>[:<sanitize class>[:<escape>[:<default>]]]]}}*
828

829
* Example::
830

831
832
833
834
  {{pId}}
  {{pId:FSE}}
  {{pId:FSE:digit}}
  {{name:FSE:alnumx:m}}
835
  {{name:FSE:alnumx:m:John Doe}}
836

837
838
839
* Zero or more stores might be specified to be searched for the given VarName.
* If no store is specified, the by default searched stores are: **FSRVD** (=FORM > SIP > RECORD > VARS > DEFAULT).
* If the VarName is not found in one store, the next store is searched,  up to the last specified store.
840
841
* If the VarName is not found and a default value is given, the default is returned.
* If no value is found, nothing is replaced - the string '{{<VarName>}}' remains.
842
* If anywhere along the line an empty string is found, this **is** a value: therefore, the search will stop.
843

849

850

851
.. _`sql-variables`:
852

853
854
SQL variables
^^^^^^^^^^^^^
855

856
857
858
* The detection of an SQL command is case *insensitive*.
* Leading  whitespace will be skipped.
* The following commands are interpreted as SQL commands:
859

860
861
862
  * SELECT
  * INSERT, UPDATE, DELETE, REPLACE, TRUNCATE
  * SHOW, DESCRIBE, EXPLAIN, SET
863

864
865
866
867
* A SQL Statement might contain parameters, including additional SQL statements. Inner SQL queries will be executed first.
* All variables will be substituted one by one from inner to outer.
* The number of variables inside an input field or a SQL statement is not limited.
* A resultset of a SQL statement will be imploded over all: concat all columns of a row, concat all rows - there is no glue string.
868

869
* Example::
870

871
872
873
  {{SELECT id, name FROM Person}}
  {{SELECT id, name, IF({{feUser}}=0,'Yes','No')  FROM Person WHERE id={{r:S}} }}
  {{SELECT id, city FROM Address AS adr WHERE adr.accId={{SELECT id FROM Account AS acc WHERE acc.name={{feUser}} }} }}
874

875
* Special case for `SELECT` input fields and FormElement.type=action `sqlValidate`. To deliver a result array specify an '!' before the SELECT: ::
876

877
   {{!SELECT ...}}
878

879

880
.. _`column-variables`:
881

882
883
884
885
886
Column variables
^^^^^^^^^^^^^^^^

Syntax:  *{{<level>.<column>}}*

887
Only used in report to access outer columns. See `access-column-values`_ and `syntax-of-report`_.
888

889
890
There might be name conflicts between VarName / SQL keywords and <line identifier>. QFQ checks first for '<level>',
than for 'SQL keywords' and than for 'VarNames' in stores.
891
892
893

All types might be nested with each other. There is no limit of nesting variables.

894
895
Very specific: Also, it's possible that the content of a variable is again (including curly braces) a variable - this
is sometimes used in text templates, where the template is retrieved from a record and
896
897
898
specific locations in the text will be (automatically by QFQ) replaced by values from other sources.

.. _`sanitize-class`:
899
900

Sanitize class
901
902
903
904
905
906
--------------

* If a value violates a parameter sanitize class, the value becomes an empty string.
* Per store there is a default if sanitizing applies and if yes, which class.

  * Store *C* (Client=Browser) and store *F* (Form) will be sanitized with 'digit'.
907

908
* All `predefined-variable-names`_ have a specific default sanitize class. For these variables, it's not necessary
909
  to specify a sanitize class.
910
* All other variables (Store: C, F) get by default the sanitize class defined in the corresponding form. If not defined,
911
912
  the default class is 'digit'.
* A default sanitize class can be overwritten by individual definition: *{{a:C:all}}*
913
914
915
* If there is a sanitized class specified, it applies to all given stores.

For QFQ variables and FormElements:

.. _`variable-escape`:

Escape
------

Variables used in SQL Statements might cause trouble by using: NUL (ASCII 0), \\n, \\r, \\, ', ", and Control-Z.

To protect the web application the following `escape` types are available:

	* 'm' - `real_escape_string() <http://php.net/manual/en/mysqli.real-escape-string.php>`_ (m = mysql)
	* 'l' - LDAP search filter values will be escaped: `ldap-escape() <http://php.net/manual/en/function.ldap-escape.php>`_ (LDAP_ESCAPE_FILTER).
	* 'L' - LDAP DN values will be escaped. `ldap-escape() <http://php.net/manual/en/function.ldap-escape.php>`_ (LDAP_ESCAPE_DN).
	* 's' - single ticks will be escaped. str_replace() of ' against \\'.
	* 'd' - double ticks will be escaped: str_replace() of " against \\".
958
959
	* 'c' - config - the escape type configured in `config.qfq.ini`_.
	* ''  - the escape type configured in `config.qfq.ini`_.
960
961
962
963
964
965
966
967
	* '-' - no escaping.

* The `escape` type is defined by the fourth parameter of the variable. E.g.: `{{name:FE:alnumx:m}}` (m = mysql).
* It's possible to combine different `escape` types, they will be processed in the order given. E.g. `{{name:FE:alnumx:Ls}}` (L, s).
* Escaping is typically necessary for SQL or LDAP queries.
* Be careful when escaping nested variables. Best is to escape **only** the most outer variable.
* In `config.qfq.ini`_ a global `ESCAPE_TYPE_DEFAULT` can be defined. The configured escape type applies to all substituted
  variables, who *do not* contain a *specific* escape type.
968
* Additionally a `defaultEscapeType` can be defined per `Form` (separate field in the *Form editor*). This overwrites the
969
970
971
  global definition of `config.qfq.ini`. By default, every `Form.defaultEscapeType` = 'c' (=config), which means the setting
  in `config.qfq.ini`_.
* To suppress a default escape type, define the `escape type` = '-' on the specific variable. E.g.: `{{name:FE:alnumx:-}}`.
972

973
974
975
976
977
Security
========

All values passed to QFQ will be:

978
979
980
981
982
983
984
985
986
987
988
989
990
991
992
993
* Checked against max. length and allowed content, on the client and on the server side. On the server side, the check
  happens before any further processing. The 'length' and 'allowed' content is specified per `FormElement`. 'alnumx' is the
  default allowed content for those. Violating the rules will stop the 'save record' process (Form) or result in an empty value (Report).

* Only elements defined in the `Form` definition or requested by `Report` will be processed.

* UTF8 normalized (normalizer::normalize) to unify different ways of composing characters. It's more a database interest
  to work with unified data.

SQL statements are typically fired as `prepared statements` with separated variables.
Further *custom* SQL statements will be defined by the webmaster - those do not use `prepared statements` and might be
affected by SQL injection. To prevent SQL injection, every variable can be escaped with `mysqli::real_escape_string` by
defining the `escape` modifier `m`.

**QFQ notice**:

994
* Variables passed by the client (=Browser) are untrusted and use the default sanitize class 'digit' (if nothing else is
995
996
  specified). If alpha characters are submitted, the content violates `digit` and becomes therefore empty - there is no
  error message. Best is to always use SIP or digits.
997
998
999
1000

Get Parameter
-------------

1001
**QFQ security restriction**:
1002

1003
1004
* GET parameter might contain urlencoded content (%xx). Therefore all GET parameter will be processed by 'urldecode()'.
  As a result a text like '%nn' in GET variables will always be decoded. It's not possible to transfer '%nn' itself.
1005
* GET variables are limited to SECURITY_GET_MAX_LENGTH chars - any violation will stop QFQ.
1006
1007
1008
1009

Post Parameter
--------------

1010
Per `FormElement` (HTML input) the default is to `htmlspecialchars()` the input. This means &<>'" will be encoded as htmlentity
1011
and saved as a htmlentity in the database. In case any of these characters (e.g. for HTML tags) are
1012
1013
1014
required, the encoding can be disabled per FormElement: `encode=none` (default is `specialchar`).

During Form load, htmlentities are decoded again.
1015
1016
1017
1018

$_SERVER
--------

1019
All $_SERVER vars are htmlentities encoded (all, not only specialchars!) .
1020
1021
1022
1023

Honeypot
--------

1024
1025
Every QFQ Form contains 'honeypot'-HTML input elements (HTML: hidden & readonly). Which of them to use is configured in
`config.qfq.ini`_ (default:   'username', 'password' and 'email'). On every start of QFQ (form, report, save, ...),
1026
1027
1028
1029
1030
these variables are tested if they are non-empty. In such a case a probably malicous bot has send the request and the
request will not be processed.

If any of the default configured variable names are needed (which will never be the case for QFQ), an explicit variable name
list have to be configured in `config.qfq.ini`_.
1031

1032
**QFQ security restriction**:
1033

1034
* The honeypot variables can't be used in GET or POST as regular HTML input elements - any values of them will terminate QFQ.
1035
1036
1037
1038

Violation
---------

1039
On any violation, QFQ will sleep SECURITY_ATTACK_DELAY seconds (`config.qfq.ini`_) and than exit the running PHP process.
1040
1041
A detected attack leads to a complete white (=empty) page.

1042
If SECURITY_SHOW_MESSAGE = true (`config.qfq.ini`_), at least a message is displayed after the delay.
1043

1044
1045
Client Parameter via SIP
------------------------
1046
1047

Links with URL parameters, targeting to the local website, are typically SIP encoded. Instead of transferring the parameter
1048
1049
as part of the URL, only one uniqe GET parameter 's' is appended at the link. The parameter 's' is uniq (equal to a
timestamp) for the user. Assigned variables are stored as a part of the PHP user session on the server.
1050
1051
1052
1053
Two users might have the same value of parameter 's', but the content is completely independet.

Variables needed by Typo3 remains on the link and are not 'sip-encoded'.

1056
1057
1058
1059
1060
1061
1062
Secure direct fileaccess
------------------------

If the application uploads files, mostly it's not necessary and often a security issue, to offer a direct download of
the uploaded files. Best is to create a directory, e.g. `fileadmin/protected` and deny direct access via webbrowser to it.
E.g. for Apache set a htaccess rule: ::

Carsten Rose committed
1063
		<Directory "/var/www/html/fileadmin/protected">
1064
1065
1066
			Require all denied
		</Directory>

1067
1068
**Important**: all QFQ uploads should then save files in or below such a directory.

1069
1070
To offer download of those files, use the reserved columnname '_download':`download`_ or variants.

1071
**Important**: To protect the installation against executing of uploaded malicious script code, disable PHP for the final upload
1072
directory. E.g. `fileadmin`: ::

Carsten  Rose's avatar
Carsten Rose committed
1075
1076
1077
			php_admin_flag engine Off
		</Directory>

1078
1079
This is in general a good security improvement for directories with user supplied content.

1080
1081
1082
1083
File upload
-----------

By default the mime type of every uploaded file is checked against a whitelist of allowed mime types. The mime type of
1084
1085
1086
a file can be (easily) faked by an attacker. This check is good to handle regular user file upload for specific file types. To
prevent attacks against uploading and executing malicous code this won't help.

1087
1088
1089
Instead prohibit the execution of user contributed files by the webserver config (`SecureDirectFileAccess`_).
