When we run SQL Injection on a server running IDS system, we often encounter a lot of trouble because our injection statements are filtered out, how to circumvent this kind of detection method has become a new technology. This article puts forward eleven ideas and methods for this technology, and discusses them with everyone.I. Bypass Using encoding technology, such as URLEncode and ASCII code.If or 1 = 1,

is updated gradually. However, when there are so many pages, it is difficult for you to detect vulnerabilities on that page one by one. if you write the following detection code, I did not expect this to be done simply, and you can use this method to optimize your SQL. Step 1 create an SQL log table The code is as follows: Create table [dbo]. [my_sqllog] ( [Id] [bigint] IDENTITY (1, 1) not null, [Hit] [bigint] NULL, [Sqltext] [varchar] (max) COLLATE
