CVE-2020-4935Network attack vector

Credential disclosure via modified input-field JavaScript

Published Jul 1, 2021 · Updated Sep 16, 2024

Cross-site scripting in IBM Datacap Navigator 9.1.7 allows remote authenticated users to run JavaScript through modified Web UI input fields. The Web UI accepts embedded JavaScript in modified input fields and executes it when that content is processed in a trusted session. A valid low-privilege session and subsequent user interaction are required, and successful exploitation can expose credentials or alter UI behavior.
