1. Preface

The injection tool under Windows is good and expensive, free Ah D, Ming boy and so on, we don't need to spend

Time to find what cracked havij, pangolin and so on, especially the tool is likely to be tied to the Trojan horse. In fact

The injection tools under Linux are also very powerful, and not too much to say, can completely replace all the injections under Windows

Tools.

As in the backtrack system there is a very rich injection tool, for MSSQL, MYSQL, Oracle and other various

Database, and these tools are free and open source, we can also be used to repair

Replace the appropriate injection tool for your own use.

This article introduces the Sqlmap is an open source penetration testing tool, it can automatically detect and use SQL

Inject the vulnerability to take over the database server. It is equipped with a powerful detection engine that provides the ultimate penetration tester with a

Many wretched features can be dragged to the library, can access the underlying file system, and can also be performed via an out-of-band connection on the operating system

's command.

2. Sqlmap Command Detailed

For ease of use I have translated the Sqlmap options, and there may be some inappropriate places,

Please point out that you can send me an e-mail: [email protected]. If I have time, I will give this tool a Chinese version.

At a minimum, you need to set one of these options to set the destination URL.

-D Direct connects directly to the database.

3. What is OOB?

The Transport Layer protocol uses out-of-band data (OUT-OF-BAND,OOB) to send some important data if the communicating party has

When important data needs to be notified, the protocol can send the data to the other person quickly. In order to send this data, the association

Instead of using the same channel as the normal data, a different channel is used. Socket mechanism support for Linux systems

Low-level protocols send and receive out-of-band data. But the TCP protocol doesn't really have out-of-band data. In order to send important co-

Protocol, TCP provides a mechanism called emergency mode (Urgentmode). The TCP protocol sets the Urg bit in the data segment, indicating

Enter emergency mode. The receiver can take special care of the emergency mode. It's easy to see that data is not easy in this way

is blocked, you can receive the data in a timely manner by capturing the Sigurg signal in our server-side program or using a

The recv function of the OOB flag is accepted.
