Sensitive Key Exposure via HTTP Transmission

Executive Summary

This vulnerability involves transmitting a sensitive key in the URL over an unencrypted HTTP connection. The request is sent via HTTP instead of HTTPS, exposing the key in plaintext across the network. Attackers monitoring network traffic could intercept and obtain the key.

Detection Guidance

To detect this vulnerability, monitor network traffic for HTTP requests containing sensitive keys in URLs. Use tools like tcpdump or Wireshark to capture and inspect packets for plaintext transmission of keys. Check web server logs for HTTP (not HTTPS) requests with key parameters.

Impact Analysis

An attacker could intercept the sensitive key, leading to unauthorized access to systems or data protected by that key. This could result in data breaches, account takeovers, or further exploitation of connected services.

Compliance Impact

This vulnerability likely violates requirements for secure data transmission in GDPR and HIPAA. GDPR mandates encryption for personal data, while HIPAA requires protection of sensitive health information. Non-compliance could result in legal penalties and reputational damage.

Mitigation Strategies

Ensure all sensitive data transmissions use HTTPS instead of HTTP to encrypt traffic. Inspect application code and configurations to identify any instances where keys or sensitive data are sent via unencrypted connections. Update or modify systems to enforce HTTPS for all relevant endpoints.
