Missing authentication allows remote PLC influence in Welker OdorEyes EcoSystem Pulse Bypass System (XL4 Controller)
Insufficient/missing authentication for a critical function in the Welker OdorEyes EcoSystem Pulse Bypass System with an XL4 Controller allows a remote attacker to influence/manipulate the device’s underlying PLC without proper safeguards or authentication. The issue is remotely reachable over the network with low attack complexity and requires no privileges or user interaction (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L).
