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:
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.
The Lua language has allowed misspelled, or uninitialized, variables to be used in a script which can eventually cause "script error" while giving no other indication of the misspelled name or invalid data.
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 ...
In Ginga-NCL, Lua is integrated as media objects (called NCLua) inside NCL (Nested Context Language) documents. GrafX2, a pixel-art editor, can run Lua scripts for simple picture processing or generative illustration. HAProxy, a reverse proxying software, may be extended with Lua starting from version 1.6.

In video games, an exploit is the use of a bug or glitch, in a way that gives a substantial unfair advantage to players using it. [1] However, whether particular acts constitute an exploit can be controversial, typically involving the argument that the issues are part of the game, and no changes or external programs are needed to take advantage ...
Also, unlike wp:templates which can be run interactively by edit-preview, the Lua script must be tested by show-preview (or run preview) of another page which uses a template which #invokes the Lua module being edited. In general, make one small change at a time, do a run show-preview, and save after a few good changes to have a version to ...
In computer programming, DLL injection is a technique used for running code within the address space of another process by forcing it to load a dynamic-link library. [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.
