AI-suggested

1. Restrict network access to port 23 (telnet) on Cognex In-Sight 2000 series devices using network segmentation and firewall rules, allowing only trusted management hosts to connect. 2. Enforce strong authentication policies and credential management to prevent unauthorized access by limiting the risk of credential compromise. 3. Monitor device logs and network traffic for unusual telnet activity or unauthorized attempts to invoke SetSerialPort or other management commands. 4. Where possible, disable telnet services in favor of more secure management protocols such as SSH, or isolate telnet management interfaces on dedicated management networks. 5. Apply principle of least privilege by reviewing and restricting user roles and permissions on the devices to ensure only necessary users have protected privileges. 6. 7. Implement compensating controls such as intrusion detection systems (IDS) tailored to detect exploitation attempts targeting this vulnerability. 8. Conduct regular security audits and penetration testing on OT environments to identify and remediate similar permission and access control weaknesses.

Description

Cognex In-Sight Explorer and In-Sight Camera Firmware expose a telnet-based service on port 23 to allow management operations such as firmware upgrades and device reboots, which require authentication. A user with protected privileges can successfully invoke the SetSerialPort functionality to modify relevant device properties (such as serial interface settings), contradicting the security model proposed in the user manual.
