What is CVE-2025-52873?

Cognex In-Sight Explorer and In-Sight Camera Firmware expose a telnet-based management service on port 23. This service allows for management operations, such as firmware upgrades and device reboots, which are intended to be accessed only with authentication. However, a user with secured privileges can exploit this service to access the SetSystemConfig functionality, enabling them to modify crucial device properties, including network settings. This undermines the security model outlined in the user manual, posing a risk to device integrity.

In-Sight 7000 series 5.x <= 6.5.1
