In-Sight 2000 series: Use of Hard-coded Password
CVE-2025-54754 is a high-severity use of hard-coded password vulnerability in In-Sight 2000 series from Cognex, with a CVSS 3.1 base score of 8.0 out of 10. It can be exploited from the same local network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected In-Sight 2000 series versions: 5.x through 6.5.1. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of In-Sight 2000 series you run against the affected versions below, and install the vendor's latest release.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
An attacker with adjacent access, without authentication, can exploit this vulnerability to retrieve a hard-coded password embedded in publicly available software. This password can then be used to decrypt sensitive network traffic, affecting the Cognex device.

The underlying weakness: Use of Hard-coded Password
The product contains a hard-coded password, which it uses for its own inbound authentication or for outbound authentication to external components.
How developers prevent this class of flaw
- For outbound authentication: store passwords outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible.
- For inbound authentication: Rather than hard-code a default username and password for first time logins, utilize a first login mode that requires the user to enter a unique strong password.
- Perform access control checks and limit which entities can access the feature that requires the hard-coded password. For example, a feature might only be enabled through the system console instead of through a network connection.
