CWE 346: Origin Validation Error
Origin validation errors could lead to information disclosure. The underlying feedback mechanism of FactoryTalk System Services that transfers the FactoryTalk Policy Manager rules to relevant devices on the network does not verify that the origin of the communication is from a legitimate local client device. This could allow a threat actor to craft a malicious website that, when visited, would send a malicious script to connect to the local WebSocket endpoint and wait for events as if it was a valid client device. If successfully exploited, this could allow a threat actor to receive information, including whether FactoryTalk Policy Manager is installed or the entire security policy. User interaction is required for successful vulnerability exploitation.
