CVE-2025-54497
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCognex 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceCognex In-Sight Explorer and In-Sight Camera Firmware expose a telnet service on port 23 for management operations. A vulnerability in the authorization mechanism allows users with protected privileges to invoke the SetSerialPort functionality to modify serial interface settings, contradicting the documented security model. This represents a privilege escalation/authorization bypass issue.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Detect if telnet service is runningScan the device for open port 23 using 'nmap -p 23 <device_ip>' or 'netstat -an | grep :23'Affected if Port 23 is open and accepting telnet connections
-
Identify users with protected privilege levelReview user account configurations in In-Sight Explorer or the camera web interface to list all users and their assigned privilege levelsAffected if Any user account is assigned the 'protected' privilege level
-
Verify SetSerialPort function accessibilityLog into the telnet management interface with a protected-privilege account and attempt to invoke or enumerate the SetSerialPort commandAffected if The SetSerialPort functionality is accessible and allows modification beyond documented limits
-
Confirm network accessibility of telnetDetermine whether port 23 is reachable from outside the trusted management network segmentAffected if Port 23 is accessible from untrusted network segments
You are affected if telnet service is running on port 23 AND at least one user has protected privilege level AND the SetSerialPort function is accessible to that user, allowing unauthorized serial interface modifications.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict network access to the telnet service via firewall rules or network segmentation. Apply vendor firmware updates when available and disable telnet if not required for operations.
