Vulnerability Title
Wiesemann & Theis: Multiple products prone to missing authentication through spoofing
Source: NVD (National Vulnerability Database)
Vulnerability 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.
