HIGH 8.0EPSS 0.34%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.34%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Multiple Wiesemann&Theis products of the ComServer Series are prone to an authentication bypass through IP spoofing. After a user logged in to the WBM of the Com-Server an unauthenticated attacker in the same subnet can obtain the session ID and through IP spoofing change arbitrary settings by crafting modified HTTP Get requests. This may result in a complete takeover of the device.
