CVE-2025-27455Network attack vector

User action manipulation via unrestricted frame embedding

Published Jul 3, 2025 · Updated Jul 3, 2025

Clickjacking in Endress+Hauser MEAC300 FNADE4 firmware 0 through 0.16.0 allows remote attackers to induce unintended actions through a crafted frame. The web application permits its pages to be embedded by another site instead of enforcing browser anti-framing restrictions, so visible decoy content can conceal actionable controls. Exploitation requires a user to open the attacker-controlled page and click the disguised interface; the consequence is limited to low-integrity modification, with no confidentiality or availability impact.
