CVSS 3.1
9.8 criticalCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVE-2021-3325
Critical (9.8). EPSS 2.3% chance of exploitation in the next 30 days.
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.
