The Adaptec Maxview application shipped with affected SIMATIC IPCs contains a hard coded, non-unique certificate to secure HTTPS connections between the browser and the local Maxview configuration application. A local attacker may use this key to decrypt intercepted local traffic between the browser and the application and could perform a man-in-the-middle attack in order to modify data in transit. Adaptec has released updates for the affected products and recommends to update to the latest versions. Siemens recommends countermeasures for products where updates are not, or not yet available.
