Sensitive Data Exposure

high
A02:2021CWE-311Data Protection

What is Data Exposure?

Applications that fail to properly protect sensitive data like financial information, healthcare records, or credentials through encryption and access controls.

How it works

Data is transmitted in cleartext (HTTP instead of HTTPS), stored without encryption, cached in browser history, leaked in error messages, exposed in URLs, or available through misconfigured cloud storage.

Impact

Identity theft, financial fraud, regulatory violations (GDPR, HIPAA, PCI DSS), reputational damage, and legal liability.

How ShieldReport detects this

ShieldReport checks for HTTPS enforcement, TLS configuration quality, exposed sensitive paths, misconfigured cloud storage, and information leakage in headers and responses.

How to fix it

Encrypt all data in transit (TLS 1.2+) and at rest. Classify data by sensitivity. Disable caching for sensitive responses. Remove sensitive data from URLs and error messages.
