This How To shows how you can use regular expressions within ASP. Objectives Overview Using a Regular Expression Validator Control Using the Regex Class Common Regular Expressions Additional Resources If you make unfounded assumptions about the type, length, format, or range of input, your application is unlikely to be robust.To validate input captured with server controls, you can use the Regular Expression Validator control. Input validation can become a security issue if an attacker discovers that you have made unfounded assumptions. This a very minimal list of tests to add to your testings: PASS " " " FAIL " " " " " Need testing :) Need to mention I took the idea of validating the possible IP address ranges in the URL while looking at other developers regular expressions I have seen in your tests, especially the one from @scottgonzales. This a very minimal list of tests to add to your testings: PASS " " " FAIL " " " " " Need testing :) I have added simple network ranges validation, the rules I used are: - valid range 1.0.0.0 - 223.255.255.255, network adresses above and including 224.0.0.0 are reserved addresses - first and last IP address of each class is excluded since they are used as network broadcast addresses since I don't think this is worth implementing completely in a regular expression, a following pass should exclude the Intranet address space: 10.0.0.0 - 10.255.255.255 172.16.0.0 - 1.255 192.168.0.0 - 192.168.255.255 the loopback and the automatic configuration address space: 127.0.0.0 - 127.255.255.255 169.254.0.0 - 169.254.255.255 while the local, multicast and and the reserved address spaces: 0.0.0.0 - 0.255.255.255 (SPECIAL-IPV4-LOCAL-ID-IANA-RESERVED) 224.0.0.0 - 239.255.255 (MCAST-NET) 240.0.0.0 - 255.255.255.255 (SPECIAL-IPV4-FUTURE-USE-IANA-RESERVED) should already be excluded by the above regular expression.

To validate other forms of input, such as query strings, cookies, and HTML control input, you can use the System. The attacker can then supply carefully crafted input that compromises your application by attempting SQL injection, cross-site scripting, and other injection attacks.

To avoid such vulnerability, you should validate text fields (such as names, addresses, tax identification numbers, and so on) and use regular expressions to do the following: Regular expression support is available to ASP. If you capture input by using server controls, you can use the Regular Expression Validator control to validate that input.

This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.

This How To shows how you can use regular expressions within ASP. Regular expressions are a good way to validate text fields such as names, addresses, phone numbers, and other user information. It is easy to just remove the unwanted parts of the validation to fit different scopes (length, precision) so I will probably add more options like the list of existing TLD (possibly grouped), the list of existing protocols and/or a fall back for a more generic protocol match too. my Java Script URI parsing library does strict URI validation as per RFC 3986. The second validation block also takes care of excluding IP address terminating with 0 or 255 (non usable network and broadcast addresses of each class C network). Code can be found at: https://github.com/garycourt/uri-js I changed it a little bit so that it's valid in Ruby.
