CVE-2024-30269

What is this vulnerability?

CVE-2024-30269 is categorized as a medium Information Exposure flaw with a CVSS base score of 5.3. Based on our vulnerability intelligence, this issue occurs when the application fails to securely handle untrusted data boundaries.

DataEase, an open source data visualization and analysis tool, has a database configuration information exposure vulnerability prior to version 2.5.0. Visiting the /de2api/engine/getEngine;.js path via a browser reveals that the platform's database configuration is returned. The vulnerability has been fixed in v2.5.0. No known workarounds are available aside from upgrading.

This architectural defect enables adversaries to bypass intended security controls, directly manipulating the application's execution state or data layer. Immediate strategic intervention is required.

Risk Assessment

Impact on Systems

✅ Credential Theft: Exposed secrets enable unauthorized access to infrastructure, cloud services, and third-party integrations.

✅ Compliance Violation: Leaking PII or credentials may violate GDPR, HIPAA, PCI-DSS, and SOC 2 requirements.

✅ Supply Chain Risk: Compromised credentials in public repositories can propagate to downstream consumers.

How to Fix and Mitigate CVE-2024-30269

1. Apply Vendor Patches: Upgrade affected components to their latest, non-vulnerable versions immediately.
2. Implement Input Validation: Ensure all user-supplied data is validated, sanitized, and type-checked before processing.
3. Deploy Runtime Protection: Use Precogs continuous monitoring to detect exploitation attempts in real time.
4. Audit Dependencies: Review and update all third-party libraries and transitive dependencies.

Defending with Precogs AI

DataEase contains an information exposure vulnerability that leaks database configuration details.

Vulnerability Code Signature

Attack Data Flow

Vulnerable Code Pattern

# ❌ VULNERABLE: Information Exposure
@app.errorhandler(500)
def internal_error(error):
    # Taint sink: returns stack trace to user
    return f"Internal Server Error: {error}", 500

Secure Code Pattern

# ✅ SECURE: Generic error message
@app.errorhandler(500)
def internal_error(error):
    # Log the detailed error internally
    app.logger.error(f"Server Error: {error}")
    # Return a generic message to the user
    return "An internal server error occurred.", 500
