CVE-2025-54818
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 proprietary protocol on TCP port 1069 to perform management operations such as modifying system properties. The user management functionality handles sensitive data such as registered usernames and passwords over an unencrypted channel, allowing an adjacent attacker to intercept valid credentials to gain access to the device.
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 · high confidenceCognex In-Sight Explorer and In-Sight Camera Firmware expose a proprietary management protocol on TCP port 1069 that transmits usernames and passwords in plaintext, allowing an adjacent attacker on the same network segment to intercept credentials and gain unauthorized access to the device.

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.
-
Identify the device modelAccess the device web interface, check the system information page, or use the Cognex In-Sight Explorer software to confirm the device is a Cognex In-Sight Camera or In-Sight Explorer system. Note the firmware version if displayed.Affected if The device is a Cognex In-Sight product (camera or In-Sight Explorer software) running any firmware version.
-
Verify TCP port 1069 is openUse a network scanner (such as nmap) or netstat command to check if TCP port 1069 is listening on the device. Example: nmap -p 1069 <device-ip> or nc -zv <device-ip> 1069.Affected if TCP port 1069 is open and accepting connections on the device.
-
Confirm network accessibility of port 1069Attempt to connect to the device on TCP port 1069 from a system on the same network segment, or review firewall rules and network segmentation to determine if an adjacent attacker could reach port 1069.Affected if Port 1069 is reachable from network segments other than trusted management networks.
-
Check if protocol encryption is disabledReview the device configuration settings in In-Sight Explorer or the web interface for the proprietary management protocol on port 1069. Look for encryption settings or security options related to the protocol.Affected if Encryption is not enabled for the proprietary protocol on port 1069, or the device configuration shows plaintext transmission is in use.
The environment is affected if a Cognex In-Sight device has TCP port 1069 exposed and accessible on the network with encryption disabled for the proprietary management protocol.

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 dataEnable encryption for the proprietary protocol or implement a secure tunnel (TLS/SSL) around communications on port 1069; alternatively, apply available firmware patches from Cognex and restrict network access through segmentation to minimize adjacent attack surface.
