Technical Description
Monitorix 3.13.0 allows remote attackers to bypass Basic Authentication in a default installation (i.e., an installation without a hosts_deny option). This issue occurred because a new access-control feature was introduced without considering that some exiting installations became unsafe, upon an update to 3.13.0, unless the new feature was immediately configured.
Remediation
Check the references section for vendor advisories and patches from fibranet. Update monitorix to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
