Official description
Cognex In-Sight Explorer and In-Sight Camera Firmware expose a service implementing a proprietary protocol on TCP port 1069 to allow the client-side software, such as the In-Sight Explorer tool, to perform management operations such as changing network settings or modifying users' access to the device.

The underlying weakness: Client-Side Enforcement of Server-Side Security
The product includes a server that relies on the client to implement a protection mechanism that is intended to protect the server.
How developers prevent this class of flaw
- If some degree of trust is required between the two entities, then use integrity checking and strong authentication to ensure that the inputs are coming from a trusted source. Design the product so that this trust is managed in a centralized fashion, especially if there are complex or numerous communication channels, in order to reduce the risks that the implementer will mistakenly omit a check in a single code path.
