CVE-2024-38862Network attack vector

Administrator credential disclosure via unmasked audit logging

Published Oct 14, 2024 · Updated Oct 14, 2024

Sensitive-data exposure in affected Checkmk releases allows remote authenticated users to read SNMP and IPMI credentials from WATO audit logs. Adding, changing, or removing host or folder credentials writes the unmasked values into the audit log instead of masking them. Administrator access to WATO or the site filesystem exposes the stored credentials without enabling configuration changes or service interruption.
