Insecure design refers to flaws or omissions at the design stage of application development that lead to vulnerabilities in the system. Unlike implementation bugs, which result from coding errors, insecure design represents a fundamental failure to consider and incorporate security principles during planning and architecture.
Remote Code Execution (RCE) refers to the ability of an attacker to execute malicious code on a target system from a remote location. This can occur through exploiting vulnerabilities in software applications, web servers, or network protocols. RCE vulnerabilities are particularly dangerous because they can allow attackers to bypass traditional security measures, granting them full control over compromised systems. Once an RCE exploit is successful, attackers can run commands, install malware, steal sensitive data, and even alter business-critical applications.
