This is AWS WAF Classic documentation.

For more information, see AWS WAF Classic in the developer guide.

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.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import * as waf from '@aws-cdk/aws-waf';
const sqlInjectionMatchTupleProperty: waf.CfnSqlInjectionMatchSet.SqlInjectionMatchTupleProperty = {
  fieldToMatch: {
    type: 'type',

    // the properties below are optional
    data: 'data',
  },
  textTransformation: 'textTransformation',
};

fieldToMatch

Type: IResolvable | FieldToMatchProperty

The part of a web request that you want to inspect, such as a specified header or a query string.

textTransformation

Type: 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.
