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

TL;DR: Exposure of Sensitive Information Due to Incompatible Policies (CWE-213) is a vulnerability where information exposed by the product conflicts with other stakeholders’ security policies, leading to unauthorized data exposure. Fix it by aligning policies and implementing strict access controls.

What is Exposure of Sensitive Information Due to Incompatible Policies?

Exposure of Sensitive Information Due to Incompatible Policies (CWE-213) is a type of security vulnerability where information exposed by the product’s functionality conflicts with other stakeholders’ security policies. As defined by the MITRE Corporation under CWE-213, and classified by the OWASP Foundation without an official mapping.

Quick Summary

Exposure of Sensitive Information Due to Incompatible Policies occurs when a product exposes sensitive information according to its own security policy but this exposure conflicts with other stakeholders’ policies. This mismatch can lead to unauthorized access and misuse of sensitive data, compromising system integrity and confidentiality.

Exposure of Sensitive Information Due to Incompatible Policies Overview

What: Exposure of sensitive information due to incompatible policies occurs when a product’s intended functionality exposes information according to the developer’s security policy, but this exposure is considered sensitive by other stakeholders such as administrators or users.

Why it matters: This mismatch can lead to unauthorized access and misuse of sensitive data, compromising system integrity and confidentiality. It often arises from misaligned security policies across different stakeholder groups within an organization.

Where it occurs: In any application that processes information according to its own internal policy but exposes this information in a way that conflicts with external stakeholders’ expectations or requirements.

Who is affected: Any user, administrator, or other entity whose sensitive data might be exposed due to policy mismatches.

Who is NOT affected: Applications and systems where security policies are aligned across all relevant stakeholder groups, ensuring consistent protection of sensitive information.

How Exposure of Sensitive Information Due to Incompatible Policies Works

Root Cause

The root cause lies in the misalignment between a product’s internal security policy and external stakeholders’ expectations regarding the handling of sensitive data. This mismatch can lead to unintended exposure of sensitive information.

Attack Flow

1. An attacker identifies that certain information is exposed according to the developer’s security policy.
2. The attacker leverages this exposure, knowing it conflicts with other stakeholders’ policies.
3. Unauthorized access or misuse of the exposed information occurs due to the policy mismatch.

Prerequisites to Exploit

• A misalignment between internal and external security policies regarding sensitive data handling.
• Access to a system that exposes sensitive information according to its own policy but is considered sensitive by external stakeholders.

Vulnerable Code

# Example of exposing sensitive data in configuration settings
config['sensitive_data'] = 'secret_key'

This code demonstrates how sensitive data might be exposed based on the product’s internal security policy, which conflicts with other stakeholders’ expectations.

Secure Code

# Ensuring alignment between internal and external policies
if not is_policy_aligned(config):
    raise ValueError("Sensitive information exposure detected")
config['sensitive_data'] = 'secret_key'

The secure code ensures that sensitive data is only exposed if the internal policy aligns with other stakeholders’ requirements.

Business Impact of Exposure of Sensitive Information Due to Incompatible Policies

Confidentiality: Unauthorized access to sensitive data can lead to loss of confidentiality, compromising private or proprietary information.

Integrity: Misuse of exposed data can result in unauthorized modifications, affecting the integrity and trustworthiness of systems.

Availability: Policy mismatches may disrupt normal operations if stakeholders cannot rely on consistent security measures.

Exposure of Sensitive Information Due to Incompatible Policies Attack Scenario

1. An attacker identifies that sensitive information is being exposed according to a product’s internal policy.
2. The attacker leverages this exposure, knowing it conflicts with other stakeholders’ policies.
3. Unauthorized access or misuse occurs due to the policy mismatch.

How to Detect Exposure of Sensitive Information Due to Incompatible Policies

Manual Testing

• Review configuration settings for potential exposures.
• Ensure alignment between internal and external security policies regarding sensitive data handling.

Automated Scanners (SAST / DAST)

Static analysis can detect misaligned configurations, while dynamic testing ensures that exposed information matches stakeholders’ expectations.

PenScan Detection

PenScan’s scanner engines such as ZAP and Wapiti actively test for policy mismatches in configuration settings.

False Positive Guidance

A real finding will show a clear conflict between internal and external policies regarding sensitive data exposure. A false positive might occur if the exposed information is not actually considered sensitive by other stakeholders.

How to Fix Exposure of Sensitive Information Due to Incompatible Policies

• Align security policies across all relevant stakeholder groups.
• Implement robust access control mechanisms to ensure consistent protection of sensitive information.

Framework-Specific Fixes for Exposure of Sensitive Information Due to Incompatible Policies

Python/Django

# Ensuring policy alignment before exposing sensitive data
if not is_policy_aligned(config):
    raise ValueError("Sensitive information exposure detected")
config['sensitive_data'] = 'secret_key'

Java

// Ensure policy alignment before exposing sensitive data
if (!isPolicyAligned(config)) {
    throw new IllegalArgumentException("Sensitive information exposure detected");
}
config.setProperty("sensitive_data", "secret_key");
