CWE-223

What is CWE-223 (Omission of Security-relevant Information)?

The product does not record or display information that would be important for identifying the source or nature of an attack.

Vulnerability Insights

Omission of Security-relevant Information (CWE-223) represents a security risk across modern software systems. This weakness enables attackers to exploit logging flaws, potentially leading to unauthorized access, data exfiltration, or system compromise. Organizations should implement defense-in-depth strategies combining static analysis, runtime monitoring, and binary analysis.

Impact on Systems

• Compromise of Application Integrity: Predictable execution flow is disrupted
• Potential Data Exposure: Depending on context, sensitive configurations may leak
• Availability Risks: Unexpected states leading to temporary denial of service

Real-World Attack Scenario

An attacker probes the system interfaces to identify areas where the input or state related to Omission of Security-relevant Information is improperly handled. Once identified, they craft a payload tailored to the specific backend architecture. By exploiting the lack of robust structural validation, the attacker is able to force the application into an unintended state, bypassing standard business logic and achieving unauthorized outcomes.

Code Examples

Vulnerable Implementation

// VULNERABLE: Unvalidated input leading to Omission of Security-relevant Information
function processInput(data) {
    // Missing strict validation or sanitization
    executeOrStoreConfig(data);
}

Secure Alternative

// SECURE: Proper validation mitigating Omission of Security-relevant Information
function processInput(data) {
    if (!isValid(data)) throw new Error('Invalid input');
    const safeData = sanitize(data);
    executeOrStoreConfig(safeData);
}
