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. A program that is designed to exploit such a ...
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 ...
Common Vulnerabilities and Exposures (CVE) is a dictionary of common names (i.e., CVE Identifiers) for publicly known information security vulnerabilities. CVE's common identifiers make it easier to share data across separate network security databases and tools, and provide a baseline for evaluating the coverage of an organization's security ...
PrintNightmare is a critical security vulnerability affecting the Microsoft Windows operating system. [2] [4] The vulnerability occurred within the print spooler service. [5] [6] There were two variants, one permitting remote code execution (CVE-2021-34527), and the other leading to privilege escalation (CVE-2021-1675).

Local file inclusion (LFI) is similar to a remote file inclusion vulnerability except instead of including remote files, only local files i.e. files on the current server can be included for execution. This issue can still lead to remote code execution by including a file that contains attacker-controlled data such as the web server's access logs.
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.
Spectre (security vulnerability) Spectre is one of the two original transient execution CPU vulnerabilities (the other being Meltdown ), which involve microarchitectural side-channel attacks. These affect modern microprocessors that perform branch prediction and other forms of speculation.
