Technical details

A vulnerability (CWE-295) exists in the Siemens Analytics Toolkit used across several Siemens products. The affected applications do not properly validate client certificates when establishing a connection to the Analytics Service endpoint. An unauthenticated remote attacker positioned between the client and the service could exploit this to perform a man-in-the-middle (MitM) attack. This could lead to the disclosure of information transmitted to the analytics service. Siemens has released updates for all affected product lines to address this validation failure.
