CWE-213

What is CWE-213 (Exposure of Sensitive Information Due to Incompatible Policies)?

The product's security policies or configurations are incompatible, inadvertently exposing sensitive information to unauthorized actors.

Vulnerability Insights

Exposure of Sensitive Information Due to Incompatible Policies (CWE-213) represents a security risk across modern software systems. This weakness enables attackers to exploit information exposure 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 Exposure of Sensitive Information Due to Incompatible Policies 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 Exposure of Sensitive Information Due to Incompatible Policies
function processInput(data) {
    // Missing strict validation or sanitization
    executeOrStoreConfig(data);
}

Secure Alternative

// SECURE: Proper validation mitigating Exposure of Sensitive Information Due to Incompatible Policies
function processInput(data) {
    if (!isValid(data)) throw new Error('Invalid input');
    const safeData = sanitize(data);
    executeOrStoreConfig(safeData);
}

Detection with Precogs AI

Precogs AI identifies exposure of sensitive information due to incompatible policies patterns through automated binary and source code analysis, detecting CWE-213 weaknesses before they reach production. Our analysis engine examines compiled artifacts without requiring source code access, identifying CWE-213 patterns in vendor software, containers, firmware, and third-party libraries.

Remediation

Implement proper information exposure controls following secure coding guidelines. Use automated scanning tools like Precogs AI to continuously monitor for CWE-213 vulnerabilities. Apply the principle of least privilege and validate all inputs from untrusted sources.
