update-sql-injection-match-set

Description

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:

  • Submit a CreateSqlInjectionMatchSet request.
  • Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.
  • Submit an 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 .

(structure)

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 .

Action -> (string)

Specify INSERT to add a SqlInjectionMatchSetUpdate to a SqlInjectionMatchSet . Use DELETE to remove a SqlInjectionMatchSetUpdate from a SqlInjectionMatchSet .

SqlInjectionMatchTuple -> (structure)

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.

FieldToMatch -> (structure)

Specifies where in a web request to look for snippets of malicious SQL code.

Type -> (string)

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 .

Data -> (string)

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 .

TextTransformation -> (string)

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:

  • Delete the following characters: " ' ^
  • Delete spaces before the following characters: / (
  • Replace the following characters with a space: , ;
  • Replace multiple spaces with one space
  • Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE

Use this option to replace the following characters with a space character (decimal 32):

  • f, formfeed, decimal 12
  • t, tab, decimal 9
  • n, newline, decimal 10
  • r, carriage return, decimal 13
  • v, vertical tab, decimal 11
  • non-breaking space, decimal 160

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:

  • Replaces (ampersand)quot; with "
  • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160
  • Replaces (ampersand)lt; with a "less than" symbol
  • Replaces (ampersand)gt; with >
  • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh; , with the corresponding characters
  • Replaces characters that are represented in decimal format, (ampersand)#nnnn; , with the corresponding characters
LOWERCASE

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.

Shorthand Syntax:

Action=string,SqlInjectionMatchTuple={FieldToMatch={Type=string,Data=string},TextTransformation=string} ...

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To update a SQL Injection Match Set

The following update-sql-injection-match-set command deletes a SqlInjectionMatchTuple object (filters) in a SQL injection match set. Because the updates value contains embedded double quotes, you must surround the entire value in single quotes. :

aws waf-regional update-sql-injection-match-set
--sql-injection-match-set-id a123fae4-b567-8e90-1234-5ab67ac8ca90 --change-token 12cs345-67cd-890b-1cd2-c3a4567d89f1 --updates 'Action="DELETE",SqlInjectionMatchTuple={FieldToMatch={Type="QUERY_STRING"},TextTransformation="URL_DECODE"}'

For more information, see Working with SQL Injection Match Conditions in the AWS WAF Developer Guide.

Output

ChangeToken -> (string)

The ChangeToken that you used to submit the UpdateSqlInjectionMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus .
