The most common way to attack a system is to enter incorrect data, and then look at the type and context of the error message. Doing so helps attackers gather information about the server to find weaknesses. For example, if an attacker knows the form information on which a page is based, he will attempt to modify the variable:

ClassLoader instance as the parent ClassLoader, and before true DefineClass, This task should be delegated to its parent class loader first . What is the appropriate ClassLoader instance?

Filters act the same as parameters in T-SQL, and can be used as data filtering. The difference between them is that the filter can filter any column in the dataset, and the T-SQL parameter can only be added in the where condition. For example:

If you are familiar with T-SQL, you will know th

Generally, Reporting Services uses the default port 80 of the web site. A recent project has special reasons (for specific reasons, we will not elaborate on it) and cannot use port 80, you need to map ports through the firewall.
As the port changes, you cannot access the report by adding an address and a port. Then, you can modify the configuration file rswebapplication. config to modify the reportserverurl node and append the port number. 1 2 3 4 5 6
