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 November 2021.
BlueKeep (CVE - 2019-0708) is a security vulnerability that was discovered in Microsoft 's Remote Desktop Protocol (RDP) implementation, which allows for the possibility of remote code execution. First reported in May 2019, it is present in all unpatched Windows NT-based versions of Microsoft Windows from Windows 2000 through Windows Server ...
PrintNightmare is a critical security vulnerability affecting the Microsoft Windows operating system. [2][5] The vulnerability occurred within the print spooler service. [6][7] There were two variants, one permitting remote code execution (CVE-2021-34527), and the other leading to privilege escalation (CVE-2021-1675). [7][8] A third ...
On September 3, 2014 iSIGHT Partners (now Mandiant) discovered a spear-phishing campaign exploiting a zero-day vulnerability via weaponized Microsoft Office documents.The vulnerability, dubbed CVE-2014-4114, affected all versions of Windows from Vista to 8.1 and allowed attackers to execute arbitrary code on a target machine.
Follina is the name given to a remote code execution (RCE) vulnerability, a type of arbitrary code execution (ACE) exploit, in the Microsoft Support Diagnostic Tool (MSDT) which was first widely publicized on May 27, 2022, by a security research group called Nao Sec. [5] This exploit allows a remote attacker to use a Microsoft Office document template to execute code via MSDT.
The vulnerability is known to affect Skylake and later processors from Intel and Zen-based processors from AMD. [54] In February 2023, a team of researchers at North Carolina State University uncovered a new code execution vulnerability called Spectre-HD, also known as "Spectre SRV" or "Spectre v6".
Code injection. Code injection is a class of computer security exploits in which a vulnerable computer program is tricked into misinterpreting external data as part of its code. An attacker thereby "injects" code into the program and changes the course of its execution. The result of successful code injection can be disastrous, for example, by ...
