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
The preceding simple SQL injection attack method has been applied.Today, we will continue to study some issues.
In the previous section, we can use some returned information to determine SQL injection. However, not all IIS on each server may return a specific error message to the client. If cint (parameter) is added to

Including the implementation and application of SQL injection, which I wrote, is also an example of this, since no filtering is encountered, so it is fairly easy to inject success, as follows:
Copy Code code as follows:

Let's take a look at the Asprox Trojan, which is mainly spread through a botnet that publishes emails. the entire working process can be described as follows: first, install the Trojan on the computer through Spam Sent by the controlled host. Then, the computer infected with the trojan will download a piece of

This will prevent attempts to secretly inject other SQL expressions (because of ADO. NET knows how to encode the string value of au_id, and avoid other data problems (for example, incorrectly converting the value type ). Note that the Ta

Measurement point positioning weaknessThe weakness of SQL Injection occurs when the program developer constructs a where clause along with user input. For example, a simple ASP program allows users to enter a customer ID and then retrieve the names
