AI-suggested
- Upgrade affected Checkmk installations to the latest patched versions (2.4.0p13, 2.3.0p38, 2.2.0p46, or later) as soon as possible to eliminate the vulnerability.
- Review and audit web server and proxy logs to ensure sensitive data is not inadvertently stored in URL query strings.
- Implement strict access controls on logs and browser histories to prevent unauthorized access.
- Educate users and administrators about the risks of transmitting sensitive data via GET requests and encourage the use of POST methods or other secure transmission mechanisms.
- Monitor network traffic for unusual access patterns that might indicate attempts to capture URL data.
- If upgrading is not immediately feasible, consider deploying web application firewalls or reverse proxies that can rewrite or block sensitive query parameters.
- Regularly review Checkmk configuration and custom scripts to avoid embedding sensitive information in URLs.
- Conduct internal penetration testing focusing on information leakage through logs and histories.
Description
Potential use of sensitive information in GET requests in Checkmk GmbH's Checkmk versions <2.4.0p13, <2.3.0p38, <2.2.0p46, and 2.1.0 (EOL) may cause sensitive form data to be included in URL query parameters, which may be logged in various places such as browser history or web server logs.
