CVE-2023-3140Network attack vector

Clickjacking via missing anti-framing headers

Published Jun 7, 2023 · Updated Jan 6, 2025

Clickjacking in KNIME Business Hub before 1.4.0 allows remote attackers to redirect user clicks through a transparent iframe. The web application omits X-Frame-Options and Content-Security-Policy framing restrictions, allowing an attacker-controlled page to overlay the Hub interface. Exploitation requires a user to visit the attacker's page and interact with the concealed interface, after which the unintended action runs with that user's Hub permissions.
