What are the CFSQLType on QueryExecute - coldfusion

When I look at
QueryExecute ("select from Artists where artistid=? and country=?",
[1, "USA"], {datasource="cfartgallery"});
I am wondering if artistid is queried as if were
<cfqueryparam cfsqltype="CF_SQL_VARCHAR" value="1">
From
https://wikidocs.adobe.com/wiki/display/coldfusionen/QueryExecute

If you need to provide additional attribute as a Query parameter (like
CFSQLType, list, and separator), you can pass these as struct against
that column name.
Example 2
QueryExecute("select from Employee where country=:country
and citizenship=:country",
{country={value='USA', CFSQLType='CF_SQL_CLOB', list=true}});

Cfquery causing XSS and SQL Injection issues

I ran an application scan (IBM) recently and now I'm trying to fix the issues that came up. A good majority of my issues stem from a cfquery (see below). I'm trying to get it so that Stored XSS and SQL injections issues don't show up on my scans. Any help would be greatly appreciated, as this is my first time doing something of the sort.
Thanks!
<cfquery name="enter_question" datasource="#dsn#">
INSERT INTO xx_questions(q_id,
q_name,
q_narrative,
q_used,
q_type)
VALUES( #variables.new_q_id#,
'#form.q_name#',
'#form.q_narrative#',
'n',
#form.q_type#)
</cfquery>
Each query that contains user inputs should have cfqueryparam like so:
<cfquery name="enter_question" datasource="#dsn#">
INSERT INTO xx_questions(q_id,
q_name,
q_narrative,
q_used,
q_type)
VALUES(
<cfqueryparam cfsqltype="CF_SQL_INTEGER" value="#variables.new_q_id#"/>,
<cfqueryparam cfsqltype="CF_SQL_CHAR" value="#form.q_name#"/>,
<cfqueryparam cfsqltype="CF_SQL_CHAR" value="#form.q_narrative#"/>,
<cfqueryparam cfsqltype="CF_SQL_CHAR" value="n"/>,
<cfqueryparam cfsqltype="CF_SQL_INTEGER" value="#form.q_type#"/>)
</cfquery>
The cfsqltype will need to reflect the data type in the xx_questions table for the cooresponding column - but you get the idea.
Binding the variable to a type in this manner automatically protects you against SQLi injection. XSS injection is something else. That's when user input is output onto the page. If a user pushes something (say a script tag) into a column in the DB and then it is output onto the page you haven't really suffered from injection (they gave you a character column, you put in a character column, they did not change the nature of the query). But in a forum app or any other area where user input from one user is shown to another you have the potential for malicious code infections.
For that each of your character types needs to be vetted for malicious code. Using something like Foundeo as a Web application Firewall can do this. You can also protect your page at a server level using the CF admin or at an application level using the scriptprotect attribute of the cfapplication tag or props in the application.cfc.
You can also manually protect within your DB inserts using HTMLEditformat like so:
<cfqueryparam cfsqltype="CF_SQL_CHAR" value="#htmleditformat(form.q_narrative)#"/>,
... or you can check each user input against a list of known allowed inputs (if the data is predictable). These techniques should be part of your "best practice" list if possible. :)
You need to use <cfqueryparam>. Check the documentation at: https://wikidocs.adobe.com/wiki/display/coldfusionen/cfqueryparam
Try something like this (you should change the CFSQLType to match whatever your DB columns are):
<cfquery name="enter_question" datasource="#dsn#">
INSERT INTO xx_questions(q_id,
q_name,
q_narrative,
q_used,
q_type)
VALUES(
<cfqueryparam value="#variables.new_q_id#" CFSQLType="CF_SQL_INTEGER">,
<cfqueryparam value="#form.q_name#" CFSQLType="CF_SQL_VARCHAR">,
<cfqueryparam value="#form.q_narrative#" CFSQLType="CF_SQL_VARCHAR">,
<cfqueryparam value="n" CFSQLType="CF_SQL_CHAR">,
<cfqueryparam value="#form.q_type#" CFSQLType="CF_SQL_INTEGER">
)
</cfquery>

Tackling Null Values while Inserting data in data base

I have the following cfquery:
<cfquery name="CQuery" datasource="XX.X.X.XXX">
INSERT INTO DatabaseName
(PhoneNumber_vch,
Company_vch,
date_dt)
VALUES(#PhoneNumber#,
#Company#,
#Date# )
</cfquery>
There are null values in case Company name doesnt' exist and I believe becasue of that Iam getting the following error:
Error Executing Database Query.
[Macromedia][SQLServer JDBC Driver][SQLServer]Incorrect syntax near ','.
The comma , pointed in the error message is after #Company# field. Please let me know is it's because of null values and best approach to fix it?
The values in the PhoneNumber, company and Date are extracted from a XML SOAP response with proper usage of trim function as discussed in my previous post.
Using cfif in coldfusion
Thanks
If you use CFQueryParam like you should on any database SQL that accepts dynamic parameters you can kill two birds with one stone. First and most important, prevent SQL Injection Attacks and second you can use the attribute of the null="" to insert a NULL value into your record.
<cfquery name="CQuery" datasource="XX.X.X.XXX">
INSERT INTO DatabaseName (PhoneNumber_vch, Company_vch, date_dt)
VALUES(
<cfqueryparam cfsqltype="cf_sql_varchar" value="#trim(PhoneNumber)#" null="#NOT len(trim(PhoneNumber))#" />
,<cfqueryparam cfsqltype="cf_sql_varchar" value="#trim(Company)#" null="#NOT len(trim(Company))#" />
,<cfqueryparam cfsqltype="cf_sql_timestamp" value="#Date#" null="#NOT len(trim(Date))#" />
)
</cfquery>
You will want to use <cfqueryparam> to take care of nulls (and injection attacks)
Try
<cfquery name="CQuery" datasource="XX.X.X.XXX">
INSERT INTO DatabaseName
(PhoneNumber_vch,
Company_vch,
date_dt)
VALUES(
<cfqueryparam value = "#PhoneNumber#" cfsqltype = "CF_SQL_VARCHAR">,
<cfqueryparam value = "#Company#" cfsqltype = "CF_SQL_VARCHAR"
null = "#IIF(Company EQ "", 1, 0)#">,
<cfqueryparam value = "#Date#" cfsqltype = "CF_SQL_TimeStamp"
null = "#IIF(Date EQ "", 1, 0)#" >
)
</cfquery>
Also see: cfqueryparam
You either need to qualify your varchar entries (surround all varchar entries with single quotes, or, better would be change them to cfqueryparams;
<cfquery name="CQuery" datasource="XX.X.X.XXX">
INSERT INTO DatabaseName
(PhoneNumber_vch,
Company_vch,
date_dt)
VALUES(<cfqueryparam value="#PhoneNumber#" cfsqltype="CF_SQL_VARCHAR">,
<cfqueryparam value="#Company#" cfsqltype="CF_SQL_VARCHAR">,
<cfqueryparam value="#Date#" cfsqltype="CF_SQL_TIMESTAMP"> )
</cfquery>

form data into database: preventing SQL injection

It has recently been mentioned to be that our method of inserting data into our SQL database via form submission is subject to SQL injection attacks, and want some advice to harden our security.
Here's the code that inserts form data into the DB:
<cfquery name="InsRegistrant" datasource="#application.Datasource#" dbtype="odbc">
INSERT INTO Schedule_Registrations(
schedule_id,
first_name,
last_name,
phone_number,
email,
guest,
list_type,
datetime_registered
)
VALUES(
#url.schedule_id#,
'#FORM.first_name#',
'#FORM.last_name#',
'#CleanPhoneNumber#',
'#FORM.email#',
#attendee.guest#,
<!--- Values for list types
0 = NEVER USE Will cause many many problems
1 = Main List
2 = Waiting List --->
#attendee.list_type#,
#createodbcdatetime(now())#
)
</cfquery>
CleanPhoneNumber is set this way:
<cfset CleanPhoneNumber = REReplace(form.phone_number, "[^0-9]", "", "ALL") />
I've been told to use, for instance,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#form.phone_number#" />
but I'm not sure what to replace and where. When I replace the values with such I get an error.
Any direction would be helpful..
You should wrap all form and url variables in cfqueryparam
Your query would look like this:
<cfquery name="InsRegistrant" datasource="#application.Datasource#" dbtype="odbc">
INSERT INTO Schedule_Registrations(
schedule_id,
first_name,
last_name,
phone_number,
email,
guest,
list_type,
datetime_registered
)
VALUES(
<cfqueryparam cfsqltype="cf_sql_integer" value="#url.schedule_id#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#FORM.first_name#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#FORM.last_name#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#CleanPhoneNumber#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#FORM.email#">,
<cfqueryparam cfsqltype="cf_sql_integer" value="#attendee.guest#">,
<!--- Values for list types
0 = NEVER USE Will cause many many problems
1 = Main List
2 = Waiting List --->
<cfqueryparam cfsqltype="cf_sql_integer" value="#attendee.list_type#">,
#createodbcdatetime(now())#
)
</cfquery>
I'm not sure I got all the data types correct, see the full documentation of cfqueryparam for all the data types.
There are several good practices you can do.
For the insert code you have provided one of the things you can do is explicitly check the input of the Form Fields before inserting the data.Check for things like spaces and "'". You also want to ensure that the user does not see your error messages from bad data entered. This is useful to somebody wanting to know your table structure.
Otherwise place the insert in a stored procedure and validate the input parameters before calling the stored procedure for the insert or update.
Here is a good list of things you can do to prevent SQL injection attacks. It is related to asp.net but the concepts still apply no matter what language you are using.
How To: Protect From Injection Attacks in ASP.NET

Using array data to drill a query

I am learning about arrays and structs, and putting together a shopping cart as a project. I am currently creating a recently viewed products module for the cart. When a user views a product i collect the product id into an array,
What is the best way to use this info to query my database, my query would be
<cfquery name="getRecent" datasource="#application.dsn#">
SELECT uid_product,txt_product_name
FROM tbl_products
</cfquery>
I thought of outputting the array as a list and using the IN operator, but not sure if that is the right way of doing it, seems a bit cumbersome? Can I use a query of queries using the array data? If so any pointers?
If you just maintain a list of productIDs then you don't need to use arrays or structs, you can just store them as a simple list and query them as follows:
<cfset recentProducts = "4,5" />
<cfquery name="getRecent" datasource="#application.dsn#">
SELECT uid_product,txt_product_name
FROM tbl_products
where productID IN (<cfqueryparam cfsqltype="cf_sql_integer" value="#recentProducts#" list="true" />)
</cfquery>
Firstly, unless you're going to put additional things into the struct, I'd say having a struct just to hold ProductID seems excessive. I'd just have the Array with the productID as each element, no struct.
So your array is structured like:
[
{ ProductID= 4 },
{ ProductID= 5 },
...
]
I'd suggest you just do:
[4,5]
This will make the next step easier. Right now I'd say you have to loop over your array, adding each productID into a list that you can then use in your query. Then modify your original query to use that list (remember and use cfqueryparam).
<cfset lstIDs = "">
<cfloop index="productStruct" array="#productsArray#">
<cfset lstIDs = listAppend(lstIDs, productStruct.ProductID)>
</cfloop>
<cfquery name="getRecent" datasource="#application.dsn#">
SELECT uid_product,txt_product_name
FROM tbl_products
WHERE productID IN <cfqueryparam value="#lstIDs#" cfsqltype="CF_SQL_INTEGER" list="yes">
</cfquery>
Or, if you simplify your array, just do ArrayToList to achieve the same thing.
<cfquery name="getRecent" datasource="#application.dsn#">
SELECT uid_product,txt_product_name
FROM tbl_products
WHERE productID IN <cfqueryparam value="#ArrayToList(productsArray)#" cfsqltype="CF_SQL_INTEGER" list="yes">
</cfquery>

can't define id ColdFusion

here is my ColdFusion code:
Example1:
<cfquery name="GET_BRAND" datasource="#dsn1#">
SELECT PRODUCT_CATID
FROM PRODUCT_CAT
WHERE PRODUCT_CATID = PRODUCT_CATID
</cfquery>
#get_brand.product_catid#
But it shows all the time number 1, i just can't understand why, and how do i make it work properly, this code should have defined the brand_id, but instead shows 1.
The system is Workcube.
Here is my example for getting from the static product's id, its dynamic price:
Example 2:
<cfset product_id = 630>
<cfquery name="price_standart" datasource="#dsn3#">
SELECT
PRICE_STANDART.PRICE PRICE
FROM
PRICE_STANDART
WHERE
PRICE_STANDART.PRODUCT_ID =
<cfqueryparam value="#product_id#" cfsqltype="cf_sql_integer">
</cfquery>
But this time i need to get from dynamic product's ID its dynamic brand id.
This script works the same way as the Example 1:
<cfquery name="GET_BRAND" datasource="#dsn1#">
SELECT BRAND_ID
FROM PRODUCT_BRANDS
WHERE BRAND_ID = BRAND_ID
</cfquery>
#get_brand.BRAND_ID#
As Andreas shows in his code, your query isn't going to work as written. The statement WHERE PRODUCT_CATID = PRODUCT_CATID doesn't actually pass a value - it would actually just be self-referential within the table values. In this case, it would return everything in the table.
You should instead have:
WHERE PRODUCT_CATID = #PRODUCT_CATID#
Where #PRODUCT_CATID# represents a variable. Better yet, use cfqueryparam as Andreas shows (this prevents SQL injection and improves query performance). However, I am not even sure that is what you intend since if you have the product ID why do you need to get it from the database? Instead, I assume you probably want to get the brands from the product in a particular category. Not knowing your table structure, it's hard to write that query for you but it might look something like:
<cfquery name="GET_BRAND" datasource="#dsn1#">
SELECT PRODUCT.BRAND_ID
FROM PRODUCT
INNER JOIN PRODUCT_CAT
ON PRODUCT.PRODUCT_CATID = PRODUCT_CAT.PRODUCT_CATID
WHERE PRODUCT_CATID = <cfqueryparam cfsqltype="cf_sql_integer" value="#product_catid#">
</cfquery>
Lastly, as both comments indicate, you would need to loop through the results to see all the records returned.
You need to wrap the statement in tags like this.
<cfquery name="GET_BRAND" datasource="#dsn1#">
SELECT PRODUCT_CATID FROM PRODUCT_CAT WHERE PRODUCT_CATID = PRODUCT_CATID
</cfquery>
<cfoutput query =GET_Brand">
#get_brand.product_catid#
</cfoutput>
It's not very clear what your question really is about, but let me guess:
<cfquery name="GET_BRAND" datasource="#dsn1#">
SELECT PRODUCT_CATID
FROM PRODUCT_CAT
WHERE PRODUCT_CATID = <cfqueryparam cfsqltype="cf_sql_integer" value="#product_catid#">
</cfquery>
where #product_catid# refers to a variable you defined earlier in your code or received via form or url scope.
<cfloop query="GET_BRAND">
#get_brand.product_catid#<br />
</cfloop>
will show a list of all the product_catid's returned by the query.
It's not too clear what you are after here, but in the queries there are at least 2 problems. First your WHERE clause
WHERE PRODUCT_CATID = PRODUCT_CATID
is like saying
WHERE 1=1
This will return the full recordset. You can see this by adding
<cfdump var="#GET_BRAND#">
under your code to see the query output. I'm guessing this will show all records in the table.
To match just one record you need your WHERE clause to be like
WHERE PRODUCT_CATID = 3
or have the #...# wrapped around the variable you are trying to match to make it dynamic.
Secondly to the query result may be more than one record, and to see any more than the first record you need to loop over the output. One way is to use
<cfoutput query="GET_BRAND">
#BRAND_ID# <br>
</cfoutput>
My guess of what you are after is
<cfset ID_TO_MATCH=3>
<cfquery name="GET_BRAND" datasource="#dsn1#">
SELECT BRAND_ID
FROM PRODUCT_CAT
WHERE PRODUCT_CATID = #ID_TO_MATCH#
</cfquery>
<cfoutput query="GET_BRAND">
#BRAND_ID# <br>
</cfoutput>
