Nozomi Networks Smart Polling: improper access control
Fix: upgrade to Guardian 26.3.0 or later (2 fixed versions below)
An access control vulnerability was discovered in the Smart Polling configuration functionality due to insufficient validation of user privileges. An authenticated user with limited privileges can remotely bypass the intended access control of the web management interface and modify the Smart Polling discovery configuration. This allows the attacker to disrupt the visibility of assets in the monitored network.
