0x01 background Today's web programs basically have a global filter for SQL injection, like PHP to open the GPC or on the global file common.php using the Addslashes () function to filter the received parameters, especially single quotes. Two injections is also a more common injection, it involves warehousing and out of the library. Because there is a global esc

); // You can also use the mysqli_real_escape_string function to replace addslashes. This will make the processing safer. Of course, you can further judge the string length to prevent "buffer overflow attacks" such as: $ str = addslashes (sprintf ("% s", $ str )); $ str = substr ($ str,); // The maximum length is 40. Parameterized binding parameterized binding prevents another barrier of

Label:With the development of B/s pattern application development, more and more programmers use this model to write applications. However, due to the lack of entry threshold in this industry, the level and experience of programmers is also uneven, a large part of the programmer in writing code, the user does not judge the legality of input data, so that the application has a security risk. The user can submit a database query code, according to the r

and architecture. The Mole The Mole is an open-source automated SQL injection tool that bypasses IPS/IDS (Intrusion Prevention System/Intrusion Detection System ). You only need to provide a URL and an available keyword to detect and exploit injection points. The Mole can use The union injection technology and The lo

error. So whether or not to prevent SQL injection, you should verify that the ID is not an integer. Verification method, you can use TryParse, you can use regular, you can write function validation. However, it is not recommended to use a try exception because of the efficiency problem. There is also a special case, is for the bulk of the deletion of this kind of will pass over several numbers, such as "1,
