Fixes https://github.com/Benjamin-Stefan/uqmi-client/security/code-scanning/1

To fix the problem, we need to ensure that sensitive information such as passwords is not logged. This can be achieved by sanitizing the messages before logging them. Specifically, we should avoid including the password field in any debug messages.

  1. Modify the logDebug function to sanitize the message before logging it.
  2. Ensure that any sensitive information is either removed or masked in the debug messages.

Clear-text logging of sensitive information High

This logs sensitive data returned by
an access to password
as clear text.

Copilot Autofix AI 5 months ago

To fix the problem, we need to ensure that no sensitive information is logged. This can be achieved by enhancing the sanitizeSensitiveData function to cover more patterns and by modifying the logDebug function to avoid logging any potentially sensitive information directly. Instead, we can log a generic message indicating that sensitive information was omitted.

  1. Enhance the sanitizeSensitiveData function to cover more patterns of sensitive data.
  2. Modify the logDebug function to log a generic message if any sensitive information is detected, regardless of the sanitization result.
