RCE

Remote Code Execution (RCE) is a critical class of vulnerability that allows an attacker to run arbitrary code on a target server or system. RCE vulnerabilities can arise from deserialization flaws, command injection, template injection, or memory corruption bugs. They typically result in full system compromise, allowing attackers to install malware, exfiltrate data, or pivot to internal networks. Log4Shell (CVE-2021-44228) is a famous example of an RCE vulnerability affecting millions of systems.
