Remote Code Execution (RCE) is one of the most serious threats in the field of IT security. It is an attack in which a malicious user manages to execute arbitrary code on a remote computer or system without authorization. Typically, these attacks exploit software weaknesses, such as vulnerabilities in applications or network systems. The consequence of an RCE attack can include gaining access to sensitive data, destroying systems, or even completely compromising an organization. Thus, detecting and addressing these vulnerabilities is critical to ensuring the security of information systems.
