code-injection

问题 Recently, my database experienced an attack from mysql injections. I did not know about injections before this incident. However, I have been studying up on what it is and how to prevent it, but I cannot seem to get anything to work for this script when I try to add sql injection protection (it works fine on it's own). How could a pdo script like this add sql injection protection? <?php $username = $_GET["hits"]; $sq = "something"; $pu = $_GET["something"]; $jjj = "something"; $fff =

问题 I am switching my MVC to use PDO (I know, overdue). My application has, in the past, used the following class hierarchy: Database.class>Main.class>User.class (each one extending the other). But before any object is created, the mysql connection was made (mysql_connect). Once the connection was open I could use Database.class as a wrapper class through which all my queries were performed. Through extention, a query in the User.class could be made simply by calling the "query" function ($this-

I would be happy if someone could suggest a solution. The code i'm thinking about looks something liek this: @Component public class ExampleService implements Service { private PlatformSetting setting1; @Required @Qualifier("setting1") public void setSetting1(PlatformSetting setting1) { this.setting1 = setting1; } public String getMessage() {

问题 I am creating a program that interacts with another program and I would like to "inject" my program into this program as an MDI Child window. Is this even possible, and if so can it be done in VB.NET? What kind of pitfalls are associated with doing this? 回答1: It could be done, in two ways, the first way, by obtaining a copy of Detours, and use pinvoke to inject your process into that parent process with MDI controller, the second way, although more dangerous, is to hook into the MDI

问题 How can I avoid mysql injections? This is the PHP file I have right now <?php include 'config.php'; $Name = $_GET['Name'] ; $sql = "Select * from tables where names =\"$Name\""; try { $dbh = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbuser, $dbpass); $dbh->query('SET CHARACTER SET utf8'); $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $stmt = $dbh->query($sql); $names = $stmt->fetchAll(PDO::FETCH_OBJ); $dbh = null; echo '{"key":'. json_encode($names) .'}'; } catch

问题 I am working with a few .Net 4.0 webforms controls such as the Menu control and while I think it's great that I can now declare the way in which controls are rendered (i.e. as either tables or divs), I can't switch off the automagically-included javascript that manages the hover events for those controls, for example: new Sys.WebForms.Menu({ element: 'NavigationMenu', disappearAfter: 500, orientation: 'horizontal', tabIndex: 0, disabled: false } This appears at the bottom of every page that

Now i want to know how do we inject code within the method ?
