Some of the main types of results of an RCE attack include: The impact of a remote code execution attack can vary between simply gaining access to an application and entirely taking it over. Some other types of remote code execution include CVE-2021-21972. Yet even without more extraordinary privilege, the remote code execution vulnerability has the potential to cause serious harm.
Unfortunately, such elevated privilege also allows attackers to hide the attack more skillfully. For example, if attackers inject code as a user, they will seize user privileges.įor this reason, RCE is frequently followed by attempts to escalate privileges and gain control on an administrative or root level.
Such languages may include PHP, Java, Python, Ruby, etc.ĭepending on the flaw that attackers exploit, they will typically acquire those privileges granted by the process they are targeting upon executing the code. Injected code is usually in the programming language of the targeted application. This can be due to user input not being validated and allowed to pass through the parser of the programming language – a situation often not intended by developers. This attack exploits the possibility of executable code being injected into a string or file and executed or evaluated.
This code can gain access to a web server or application, completely control or compromise it, open backdoors, seize, modify or destroy data, install ransomware, etc. It is a way to remotely inject and execute code in a target machine or system using the internet, local (LAN), or wide area networks (WAN). Here’s what you need to know about this attack, how it works, and how to prevent it.Īlso known as remote code evaluation, RCE is part of the broader group of arbitrary code execution (ACE) attacks. Remote Code Execution (RCE) allows attackers to execute malicious code on systems and devices, regardless of their location.
