# Detecting Information Disclosure

> Detects information disclosure vulnerabilities including sensitive data in logs, error message exposure, and memory leaks. Use when analyzing logging practices, error handling, or investigating data leakage issues. Use when this capability is needed.

# Information Disclosure Detection

## Detection Workflow

1. **Identify sensitive data flows**: Find where sensitive data is handled, trace data through application, identify all output points
2. **Check logging practices**: Analyze log statements, check error messages, review debug output
3. **Assess exposure points**: Identify all user-facing output, check external API responses, review file system artifacts
4. **Evaluate impact**: What information is disclosed? How sensitive is it? Who can access it?

## Key Patterns

- Sensitive data in logs: passwords, keys, stack traces in production logs
- Error message disclosure: detailed errors revealing system info, paths, database queries
- Memory disclosure: uninitialized memory reads, out-of-bounds reads, format string leaks
- Storage disclosure: plaintext storage, weak encryption, insecure file permissions

## Output Format

Report with: id, type, subtype, severity, confidence, location, sensitive data type, disclosure point, vulnerability description, exposure scope, risk, mitigation.

## Severity Guidelines

- **CRITICAL**: Disclosure of cryptographic keys or passwords
- **HIGH**: Disclosure of sensitive user data
- **MEDIUM**: Disclosure of system information
- **LOW**: Disclosure of minor debug information
