In-Sight 2000 series: Cleartext Transmission of Sensitive Information
CVE-2025-47698 is a high-severity cleartext transmission of sensitive information vulnerability in In-Sight 2000 series from Cognex, with a CVSS 4.0 base score of 8.6 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 0.14% 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 adjacent attacker without authentication can exploit this vulnerability to retrieve a set of user-privileged credentials. These credentials are present during the firmware upgrade procedure.

The underlying weakness: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How developers prevent this class of flaw
- Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
