CVE-2023-6287

Password disclosure via logged backup GET parameters

Published Nov 27, 2023 · Updated Aug 26, 2024

Sensitive data exposure in Webconf in Checkmk Appliance before 1.6.8 allows local users to retrieve passwords from log files. Webconf places backup passwords in GET query parameters, and the appliance records those request URLs in logs readable by a low-privileged account. A local low-privileged session is required, and the reported consequence is password disclosure without integrity or availability impact.
