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()

58
For the `download`_ function, the programs `pdftk` and `file` are necessary to concatenate PDF files.
59

60
61
Preparation for Ubuntu 14.04::

62
63
	sudo apt-get install php5-mysqlnd php5-intl
	sudo apt-get install pdftk file                # for file upload and PDF
64
65
66
	sudo php5enmod mysqlnd
	sudo service apache2 restart

Preparation for Ubuntu 16.04::

69
	sudo apt install php7.0-intl
70
	sudo apt install pdftk libxrender1 file        # for file upload, PDF and 'HTML to PDF' (wkhtmltopdf)
71

72
.. _wkhtml:
73

74
75
wkhtmltopdf
^^^^^^^^^^^
76

77
78
`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.
79

80
* The Ubuntu package `wkhtmltopdf` needs a running Xserver - this does not work on a headless webserver. Best is to
81
  install the QT version from the named website above.
82

83
In `config-qfq-ini`_ specify the:
84

85
86
87
88
89
90
91
92
* installed `wkhtmltopdf` binary:

  * `WKHTMLTOPDF = /.../wkhtmltopdf`

* the site base URL:

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

93

94
95
**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.
96
97

Configure via Typo3 Installtool `All configuration > $TYPO3_CONF_VARS['FE']`: ::
98
99
100

   [FE][lockIP] = 0

101
102
103
104
105
**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.

106
107
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

117
`print.php` with uses `wkhtmltopdf` to convert HTML to PDF.

119
120
121
122
123
124
125
126
127
128
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 {
129
		wrap = <a href="typo3conf/ext/qfq/qfq/api/print.php?id=|&type=2"><span class="glyphicon glyphicon-print" aria-hidden="true"></span> Printview</a>

	}

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.

147
148
* When the QFQ Extension is called the first time on the Typo3 Frontend, the file *<ext_dir>/qfq/sql/formEditor.sql* will
  played and fills the database with the *FormEditor* 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}}

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.

453
.. _`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
454
the end. E.g. `my_long_variable_130`. Such a variable has an allowed length of 130 chars. Access the variable as
455
456
457
usual with the variable name: `{{my_long_variable_130:C:...}}`.

466
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
467
468
server). For a development server instead, deactivate the forbid rule of 'documentation'. In `.htaccess` (snippet from
Typo3 7.6 _.htaccess): ::
469

470
471
  production:   RewriteRule (?:typo3conf/ext|typo3/sysext|typo3/ext)/[^/]+/(?:Configuration|Resources/Private|Tests?|Documentation|docs?)/ - [F]
  development:  RewriteRule (?:typo3conf/ext|typo3/sysext|typo3/ext)/[^/]+/(?:Configuration|Resources/Private|Tests?|docs?)/ - [F]

SIPs
----

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

483
The SIPs (=Server Id Pairs) are uniq timestamps, created/registered on the fly for a specific browser session (=user). Every SIP is
484
485
486
487
488
489
490
491
492
493
494
495
496
497
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.

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

The Typo3 FE Groups can be used to implement access privileges. Such groups are assigned to
503

504
505
506
507
508
509
510
* 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
511
512
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.

* *SQL_LOG*

  * Filename where to log SQL queries and statistical data.
  * File is relative to the extension directory or absolute (starting with '/').
  * Content: SQL queries and timestamp, formName/formId, fe_user, success, affected rows, newly created record
    id's and accessed from IP.
  * The global setting can be overwritten by defining `sqlLog` inside of a QFQ tt-content record.

Variable
========
641

642
643
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:
644

645
646
647
* `store-variables`_
* `sql-variables`_
* `column-variables`_
648

649
Some examples, including nesting::
650

651
652
653
654
655
  # Store
  #---------------------------------------------
  {{r}}
  {{index:FS}}
  {{name:FS:alnumx:s}}
656

657
658
659
  # SQL
  #---------------------------------------------
  {{SELECT name FROM person WHERE id=1234}}
660

661
662
663
664
  # Columns
  #---------------------------------------------
  {{10.pId}}
  {{10.20.pId}}
665

666
667
668
669
670
  # 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
671
672


673
Leading and trailing spaces inside curly braces are removed.
674

675
676
  * *{{ SELECT "Hello World"   }}* becomes *{{SELECT "Hello World"}}*
  * *{{ varname   }}* becomes *{{varname}}*

.. _`store-variables`:
682

683
684
Store variables
^^^^^^^^^^^^^^^
685

686
Syntax:  *{{VarName[:<store / prio>[:<sanitize class>[:<escape>]]]}}*
687

688
* Example::
689

690
691
692
693
  {{pId}}
  {{pId:FSE}}
  {{pId:FSE:digit}}
  {{name:FSE:alnumx:m}}
694

695
696
697
698
699
* 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.
* If the VarName is not found in any store, nothing is replaced - the string '{{<VarName>}}' remains.
* If anywhere along the line an empty string is found, this **is** a value: therefore, the search will stop.

.. _`sql-variables`:
709

710
711
SQL variables
^^^^^^^^^^^^^
712

713
714
715
* The detection of an SQL command is case *insensitive*.
* Leading  whitespace will be skipped.
* The following commands are interpreted as SQL commands:
716

717
718
719
  * SELECT
  * INSERT, UPDATE, DELETE, REPLACE, TRUNCATE
  * SHOW, DESCRIBE, EXPLAIN, SET
720

721
722
723
724
* 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.
725

726
* Example::
727

728
729
730
  {{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}} }} }}
731

732
* Special case for `SELECT` input fields and FormElement.type=action `sqlValidate`. To deliver a result array specify an '!' before the SELECT: ::
733

734
   {{!SELECT ...}}
735

736

737
.. _`column-variables`:
738

739
740
741
742
743
Column variables
^^^^^^^^^^^^^^^^

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

744
Only used in report to access outer columns. See `access-column-values`_ and `syntax-of-report`_.
745

746
747
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.
748
749
750

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

751
752
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
753
754
755
specific locations in the text will be (automatically by QFQ) replaced by values from other sources.

.. _`sanitize-class`:
756
757

Sanitize class
758
759
760
761
762
763
--------------

* 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'.
764

765
* All `predefined-variable-names`_ have a specific default sanitize class. For these variables, it's not necessary
766
  to specify a sanitize class.
767
* All other variables (Store: C, F) get by default the sanitize class defined in the corresponding form. If not defined,
768
769
  the default class is 'digit'.
* A default sanitize class can be overwritten by individual definition: *{{a:C:all}}*
770
771
772
* If there is a sanitized class specified, it applies to all given stores.

.. _`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 \\".
	* '-' - 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.
* Additionally a `defaultEscapeType` can be defined per `Form` (separate field in the Form Editor). This overwrites the
  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:-}}`.
827

828
829
830
831
832
Security
========

All values passed to QFQ will be:

833
834
835
836
837
838
839
840
841
842
843
844
845
846
847
848
* 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**:

849
* Variables passed by the client (=Browser) are untrusted and use the default sanitize class 'digit' (if nothing else is
850
851
  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.
852
853
854
855

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

856
**QFQ security restriction**:
857

858
859
* 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.
860
* GET variables are limited to SECURITY_GET_MAX_LENGTH chars - any violation will stop QFQ.
861
862
863
864

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

865
Per `FormElement` (HTML input) the default is to `htmlspecialchars()` the input. This means &<>'" will be encoded as htmlentity
866
and saved as a htmlentity in the database. In case any of these characters (e.g. for HTML tags) are
867
868
869
required, the encoding can be disabled per FormElement: `encode=none` (default is `specialchar`).

During Form load, htmlentities are decoded again.
870
871
872
873

$_SERVER
--------

874
All $_SERVER vars are htmlentities encoded (all, not only specialchars!) .
875
876
877
878

Honeypot
--------

879
880
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, ...),
881
882
883
884
885
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`_.
886

887
**QFQ security restriction**:
888

889
* The honeypot variables can't be used in GET or POST as regular HTML input elements - any values of them will terminate QFQ.
890
891
892
893

Violation
---------

894
On any violation, QFQ will sleep SECURITY_ATTACK_DELAY seconds (`config.qfq.ini`_) and than exit the running PHP process.
895
896
A detected attack leads to a complete white (=empty) page.

897
If SECURITY_SHOW_MESSAGE = true (`config.qfq.ini`_), at least a message is displayed after the delay.
898

899
900
Client Parameter via SIP
------------------------
901
902

Links with URL parameters, targeting to the local website, are typically SIP encoded. Instead of transferring the parameter
903
904
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.
905
906
907
908
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'.

909
910
.. _`SecureDirectFileAccess`:

911
912
913
914
915
916
917
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's avatar
Carsten Rose committed
918
		<Directory "/var/www/html/fileadmin/protected">
919
920
921
			Require all denied
		</Directory>

922
923
**Important**: all QFQ uploads should then save files in or below such a directory.

924
925
To offer download of those files, use the reserved columnname '_download':`download`_ or variants.

926
**Important**: To protect the installation against executing of uploaded malicious script code, disable PHP for the final upload
927
directory. E.g. `fileadmin`: ::
Carsten  Rose's avatar
Carsten Rose committed
928

Carsten  Rose's avatar
Carsten Rose committed
929
		<Directory "/var/www/html/fileadmin">
Carsten  Rose's avatar
Carsten Rose committed
930
931
932
			php_admin_flag engine Off
		</Directory>

933
934
This is in general a good security improvement for directories with user supplied content.

935
936
937
938
File upload
-----------

By default the mime type of every uploaded file is checked against a whitelist of allowed mime types. The mime type of
939
940
941
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.

942
943
944
Instead prohibit the execution of user contributed files by the webserver config (`SecureDirectFileAccess`_).

* Default *<prio>*: *FSRVD* - Form / SIP / Record / Vars / Table definition.
* Hint: Preferable, parameter should be submitted by SIP, not by Client (=URL).

  * Warning: Data submitted via 'Client' can be easily spoofed and altered.
  * Best: Data submitted via SIP never leaves the server, cannot be spoofed or altered by the user.
  * SIPs can _only_ be defined by using *Report*. Inside of *Report* use columns 'Link' (with attribute 's'), 'page?' or 'Page?'.

* *typeAheadLimit*: there might be a hard limit on the server side (e.g. 100) - which can't be extended.
1298
1299
* *ldapUseBindCredentials* is only necessary if `anonymous` access is not possible. RDN and password has to be configured in
  `config.qfq.ini`.

.. _LDAP_Typeahead:

Typeahead (TA)
--------------

*Typeahead* offers continous searching of a LDAP directoy by using a regular *FormElement* of type *text*.
The *FormElement.parameter*=*typeAheadLdap* will trigger LDAP searches on every user **keystroke**
(starting after *typeAheadMinLength* keystrokes) for the current *FormElement* - this is different from *dynamicUpdate*
(triggered by leaving focus of an input element). Typeahead delivers a list of elements.

* *FormElement.parameter.typeAheadLdap* - activate the mode *Typeahead* - no value is needed, the existence is suffucient.
* *Form.parameter* or *FormElement.parameter*:

  * *ldapServer* = `directory.example.com`
  * *ldapBaseDn* =  `ou=Addressbook,dc=example,dc=com`
1316
  * *typeAheadLdapSearch* = `(|(cn=*?*)(mail=*?*))`

* *typeAheadLdapValuePrintf*, shown to the user in a drop-down box and
1324
* *typeAheadLdapIdPrintf*, which represents the final data to save.

1326
1327
The `id/value` translation is compareable to a regular select drop-down box with id/value pairs.
Only attributes, defined in *typeAheadLdapValuePrintf* / *typeAheadLdapIdPrintf* will be fetched from the LDAP directory.

To examine all possible values of an LDAP server, use the commandline tool `ldapsearch`. E.g.::

  ldapsearch -x -h directory.example.com -L -b ou=Addressbook,dc=example,dc=com "(mail=john.doe@example.com)"

All occurences of a '?' in *ldapSearch* will be replaced by the user data typed in via the text-*FormElement*.
The typed data will be escaped to fullfill LDAP search limitations.
1334
Regular *Form* variables might be used on all parameter and will be evaluated during form load (!) - *not* at the time when

the user types something.

1337
1338
1339
1340
1341
Pedantic
^^^^^^^^

In case the typed value (technically this is the value of the *id*, latest in the moment when loosing the focus) have
to be a valid (= exist on the LDAP server), the *typeAheadPedantic* mode can be activated.
1342
If the user typed something and that is not a valid *id*, the client (=browser) will delete the input when loosing the focus.
1343
To identify the exact *id*, an additional search filter is necessary: `ypeAheadLdapSearchPrefetch` - see next topic.
1344
1345
1346
1347

* *Form.parameter* or *FormElement.parameter*:

  * *typeAheadPedantic*

1357

Prefetch
^^^^^^^^

After 'form load' with an existing record, the user epects to see the previous saved data. In case there is an *id* to
*value* translation, the *value* does not exist in the database, instead it has to be fetched again dynamically from the
LDAP server. A precise LDAP query has to be defined to force this:

* *Form.parameter* or *FormElement.parameter*:

1358
1359
  * *typeAheadLdapSearchPrefetch* = `(mail=?)`

1360
1361
This situation also applies in *pedantic* mode to verify the user input after each change.

1362
1363
1364
PerToken
^^^^^^^^

1365
1366
1367
Sometimes a LDAP server only provides attributes like 'sn' and 'givenName', but not 'displayName' or another practial
combination of multiple attributes - than it is difficult to search for 'firstname' *and* (=human AND) 'lastname'.
E.g. 'John Doe', results to search like `(|(sn=*John Doe*)(givenName=*John Doe*))` which will be probably always be empty.
