High (7.2) in nexxtsolutions nebula300plus firmware. EPSS 0.1% chance of exploitation in the next 30 days.
Nexxt Solutions Nebula 300+ firmware through version 12.01.01.37 does not implement CSRF protections on state-changing endpoints such as /goform/setSysTools and other administrative interfaces. As a result, an attacker can craft malicious web requests that are executed in the context of an authenticated administrator’s browser, leading to unauthorized configuration changes, including enabling services or modifying system settings.
