Attack Android injection 5In Android, almost all IPC communication is through the Binder. It can be said that the Binder occupies a very important position in Android. IPC communication generally involves two parts: client and server. on Android, all the serivce parts of the Binder are collectively referred to as NativeService (which is different from what is usually called the Service component ), A Native
After using 360 to detect a site vulnerability, an article was sent to address the vulnerability, in this. But many children's shoes have some problems, many children's shoes are stuck in the variable name of this step, do not know how to find and add code, indeed, because each of the variable name of the program is not the same, and how to ensure the universality of the code, today we come to the hands of the church everyone, How to find and add code through regular expressions.

In the previous blog: http://blog.csdn.net/suwei19870312/article/details/7579667. This section describes the interaction between client code and server code.
The client code passes a parameter q to the server code user. php through the get method,
In the user. PHP code, use the parameter q to construct an SQL statement for accessing the database:
$ SQL = "select * from user where id = '". $ Q ."'";
$ Result = mysql_query ($ SQL );
If the parameter q = "'or '1' = '1" passed by the client at
It is not particularly difficult to prevent the ASP.net application from being hacked into by SQL injection, as long as you filter all the input before using the contents of the form input to construct the SQL command. Filter input can be done in a variety of ways.
⑴ for dynamically constructing SQL queries, you can use the following techniques:
First: Replace single quotes, that is, to change all individual single quotes into two single quotes, to
In the previous "Java programming" build a simple JDBC connection-drivers, Connection, Statement and PreparedStatement we described how to use the JDBC driver to establish a simple connection, and realize the use of statement and PreparedStatement database query, this blog will continue the previous blog through SQL injection attack comparison statement and PreparedStatement. Of course, there are many other

, if it is used by a malicious user, it will simply "allow" specially designed attacks as required, as we have described earlier.
We will assume that you will not intentionally or even accidentally construct a destructive database query-so we assume the problem is in terms of input from your users. Now, let's take a closer look at the various ways in which users might provide information to your scripts.

This article mainly introduces the command attack in the common attack mode of PHP website. command injection, an order injection attack, is a means by which a hacker changes the dynamically generated content of a Web page by inputting HTML code into an input mechanism, such
variable to maliciously tamper with the original SQL syntax when filling in the command string.
The main reason for SQL injection attacks is due to the following two reasons:
1. The MAGIC_QUOTES_GPC option in the PHP configuration file php.ini is not opened and is set to off;
2. Developers do not check and escape data types.
But in fact, the 2nd is the most important. I think that it is the most basic quality of a web programmer to check the data
the background of SQL is "select field1,field2 from table where id=", at this time the foreground input "5 or 1=1", even single quotation marks can be omitted, more direct injection.2. As you can see, SQL injection is rigged in the conditional statement in where, and the foreground is passed to the matching object in the where, which is the basic principle of SQL injec
