Credentials exposed in logs

Risk: medium

Description

While logging all information may be helpful during development stages, it is important that logging levels be set appropriately before a product ships so that sensitive user data and system information are not accidentally exposed to potential attackers.

Recommendation

To avoid leaking credentials in application logs, consider the following:

• Ensure that your logging framework or system does not include sensitive information like passwords or API keys in logs. Review your code for any sensitive data being logged.
• Set logging levels to debug to avoid having sensitive information logged in production app.
• Remove debug log files before deploying the application into production.
• Adjust configurations appropriately when software is transitioned from a debug state to production.
• Remove any test credentials or hardcoded credentials before deploying the application.
