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:
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). [1][2] SQL injection must exploit a security vulnerability in an application's software, for example, when user ...
Dependency injection. Dependency injection is often used alongside specialized frameworks, known as 'containers', to facilitate program composition. In software engineering, dependency injection is a programming technique in which an object or function receives other objects or functions that it requires, as opposed to creating them internally.
Compile-time injection is an injection technique where source code is modified to inject simulated faults into a system. One method is called mutation testing which changes existing lines of code so that they contain faults. A simple example of this technique could be changing a = a + 1 to a = a – 1
DLL injection is often used by external programs to influence the behavior of another program in a way its authors did not anticipate or intend. [1][2][3] For example, the injected code could hook system function calls, [4][5] or read the contents of password textboxes, which cannot be done the usual way. [6]
Defensive programming is an approach to improve software and source code, in terms of: General quality – reducing the number of software bugs and problems. Making the source code comprehensible – the source code should be readable and understandable so it is approved in a code audit. Making the software behave in a predictable manner ...
Prompt injection is a family of related computer security exploits carried out by getting a machine learning model (such as an LLM) which was trained to follow human-given instructions to follow instructions provided by a malicious user. This stands in contrast to the intended operation of instruction-following systems, wherein the ML model is ...
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 ...
