High (7.2) in weidmueller. EPSS 1.1% chance of exploitation in the next 30 days.
In Weidmueller Industrial WLAN devices in multiple versions an exploitable authentication bypass vulnerability exists in the hostname processing.

An attacker can send authenticated SNMP requests to trigger this vulnerability.
