update_sql_injection_match_set
(**kwargs)¶Note
This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.
For the latest version of AWS WAF , use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.
Inserts or deletes SqlInjectionMatchTuple objects (filters) in a SqlInjectionMatchSet. For each SqlInjectionMatchTuple
object, you specify the following values:
Action
: Whether to insert the object into or delete the object from the array. To change a SqlInjectionMatchTuple
, you delete the existing object and add a new one.FieldToMatch
: The part of web requests that you want AWS WAF to inspect and, if you want AWS WAF to inspect a header or custom query parameter, the name of the header or parameter.TextTransformation
: Which text transformation, if any, to perform on the web request before inspecting the request for snippets of malicious SQL code. You can only specify a single type of TextTransformation.You use SqlInjectionMatchSet
objects to specify which CloudFront requests that you want to allow, block, or count. For example, if you're receiving requests that contain snippets of SQL code in the query string and you want to block the requests, you can create a SqlInjectionMatchSet
with the applicable settings, and then configure AWS WAF to block the requests.
To create and configure a SqlInjectionMatchSet
, perform the following steps:
ChangeToken
parameter of an UpdateIPSet request.UpdateSqlInjectionMatchSet
request to specify the parts of web requests that you want AWS WAF to inspect for snippets of SQL code.For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

[REQUIRED]
The SqlInjectionMatchSetId
of the SqlInjectionMatchSet

is returned by CreateSqlInjectionMatchSet and by ListSqlInjectionMatchSets.
[REQUIRED]
The value returned by the most recent call to GetChangeToken.
[REQUIRED]
An array of SqlInjectionMatchSetUpdate
objects that you want to insert into or delete from a SqlInjectionMatchSet. For more information, see the applicable data types:

Note
This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.
For the latest version of AWS WAF , use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.
Specifies the part of a web request that you want to inspect for snippets of malicious SQL code and indicates whether you want to add the specification to a SqlInjectionMatchSet or delete it from a SqlInjectionMatchSet
.
Specify INSERT
to add a SqlInjectionMatchSetUpdate to a SqlInjectionMatchSet. Use DELETE
to remove a SqlInjectionMatchSetUpdate
from a SqlInjectionMatchSet
.
Specifies the part of a web request that you want AWS WAF to inspect for snippets of malicious SQL code and, if you want AWS WAF to inspect a header, the name of the header.
Specifies where in a web request to look for snippets of malicious SQL code.
The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:
HEADER
: A specified request header, for example, the value of the User-Agent
or Referer
header. If you choose HEADER
for the type, specify the name of the header in Data
.METHOD
: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE
, GET
, HEAD
, OPTIONS
, PATCH
, POST
, and PUT
.QUERY_STRING
: A query string, which is the part of a URL that appears after a ?
character, if any.URI
: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg
.BODY
: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192
bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.SINGLE_QUERY_ARG
: The parameter in the query string that you will inspect, such as UserName or SalesRegion . The maximum length for SINGLE_QUERY_ARG
is 30 characters.ALL_QUERY_ARGS
: Similar to SINGLE_QUERY_ARG
, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString
.When the value of Type
is HEADER
, enter the name of the header that you want AWS WAF to search, for example, User-Agent
or Referer
. The name of the header is not case sensitive.
When the value of Type
is SINGLE_QUERY_ARG
, enter the name of the parameter that you want AWS WAF to search, for example, UserName
or SalesRegion
. The parameter name is not case sensitive.
If the value of Type
is any other value, omit Data
.
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch
before inspecting it for a match.
You can only specify a single type of TextTransformation.
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
COMPRESS_WHITE_SPACE
also replaces multiple spaces with one space.HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE
performs the following operations:
(ampersand)quot;
with "
(ampersand)nbsp;
with a non-breaking space, decimal 160(ampersand)lt;
with a "less than" symbol(ampersand)gt;
with >
(ampersand)#xhhhh;
, with the corresponding characters(ampersand)#nnnn;
, with the corresponding charactersLOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify NONE
if you don't want to perform any text transformations.
