A classification of SQL injection attacking vector as of 2010. In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).
Code injection is the malicious injection or introduction of code into an application. Some web servers have a guestbook script, which accepts small messages from users and typically receives messages such as: Very nice site! However, a malicious person may know of a code injection vulnerability in the guestbook and enter a message such as:
The concept of "Google hacking" dates back to August 2002, when Chris Sullo included the "nikto_google.plugin" in the 1.20 release of the Nikto vulnerability scanner. [4] In December 2002 Johnny Long began to collect Google search queries that uncovered vulnerable systems and/or sensitive information disclosures – labeling them googleDorks.
Injection exploits are computer exploits that use some input or data entry feature to introduce some kind of data or code that subverts the intended operation of the system. Usually these exploits exploit vulnerabilities resulting from insufficient data validation on input and so forth.
Cross-site scripting (XSS) [a] is a type of security vulnerability that can be found in some web applications.XSS attacks enable attackers to inject client-side scripts into web pages viewed by other users.
An example layout of a call stack. The subroutine DrawLine has been called by DrawSquare.Note that the stack is growing upwards in this diagram. Return-oriented programming is an advanced version of a stack smashing attack.
On its own, an arbitrary code execution exploit will give the attacker the same privileges as the target process that is vulnerable. [11] For example, if exploiting a flaw in a web browser, an attacker could act as the user, performing actions such as modifying personal computer files or accessing banking information, but would not be able to perform system-level actions (unless the user in ...
Magic quotes were enabled by default in new installations of PHP 3 and 4, but could be disabled through the magic_quotes_gpc configuration directive. Since the operation of magic quotes was behind the scenes and not immediately obvious, developers may have been unaware of their existence and the potential problems that they could introduce.
