CVE-2019-17333Network attack vector

Authenticated stored XSS

Published Feb 19, 2020 · Updated Sep 17, 2024

Cross-site scripting in the TIBCO EBX web server allows remote authenticated users to execute stored scripts through crafted input. The vendor identifies the web server component but does not disclose the specific input field, endpoint, or encoding operation that permits persistence. An authenticated user must submit the stored content and another user must load the affected web interface; the reported consequence is potential administrative access through script execution.
