Arbitrary code execution. In computer security, arbitrary code execution ( ACE) is an attacker's ability to run any commands or code of the attacker's choice on a target machine or in a target process. [1] An arbitrary code execution vulnerability is a security flaw in software or hardware allowing arbitrary code execution.
RCE - Remote Code Execution is a dystopian science fiction novel by the German-Swiss author Sibylle Berg, published in April 2022 by Kiepenheuer & Witsch. It follows her work GRM. Brainfuck, and features some of the same characters, but stands alone and is not a direct sequel to it.
Log4Shell ( CVE-2021-44228) is a zero-day vulnerability in Log4j, a popular Java logging framework, involving arbitrary code execution. [2] [3] The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud 's security team on 24 ...
Remote procedure call. In distributed computing, a remote procedure call ( RPC) is when a computer program causes a procedure (subroutine) to execute in a different address space (commonly on another computer on a shared computer network ), which is written as if it were a normal (local) procedure call, without the programmer explicitly writing ...
Shellcode. In hacking, a shellcode is a small piece of code used as the payload in the exploitation of a software vulnerability. It is called "shellcode" because it typically starts a command shell from which the attacker can control the compromised machine, but any piece of code that performs a similar task can be called shellcode.

Remote evaluation — A client sends code to a remote machine for execution. Code on demand — A client downloads code from a remote machine to execute locally. Mobile agents — Objects or code with the ability to migrate between machines autonomously. Viruses. Mobile code can also download and execute in the client workstation via email.
Exploit (computer security) An exploit (from the English verb to exploit, meaning "to use something to one’s own advantage") is a piece of software, a chunk of data, or a sequence of commands that takes advantage of a bug or vulnerability to cause unintended or unanticipated behavior to occur on computer software, hardware, or something ...
