0x01 backgroundThe current Web application's protection against SQL injection is basically to determine if the GPC is turned on, and then use the Addlashes function to escape special characters such as single quotes. But the only use of such protection is a lot of blind spots, such as the most classic integer parameter transfer, which is brought into the database query parameters are integer, the key in the array is not filtered into the query and the
